Possible Civic Brake Swaps.

[ronjdm36]

i will try to post this info as accurately as before, i am really tired right now,so i might forget a couple thing. if anyone wants to correct or add something just post it up. i am going to include cars other than coupes, for information purposed only. these are all ones that i have done personally or know correct info on.enjoy.

REAR BRAKE SWAPS: WHAT YOU NEED.......

FOR 88-91 CIVIC:

88-91 CRX-any rear disc equipped model
88-98 Civic-any rear disc equipped model
90-01 Integra-any rear disc equipped model.
99-00 Civic Si

you will use the complete setup from any car, but you must use your stock lca's for it to work correctly. you may want to upgrade your master cylinder to something bigger and add a proprtioning valve from a vehicle equipped with 4-wheel disc.


FOR 92-95 CIVIC:

88-98 Civic-any rear disc equipped model.
90-01 Integra- any rear disc equipped model.
99-00 Civic Si


you will use the complete setup also, but you may use your stock lca's, Integra ones, or even ITR ones, if you want to use the ITR spec rear struts.
you may also want to upgrade the master cylinder and prop valve.


FOR 96-98 CIVIC:

88-98 Civic- any rear disc equipped model.
90-01 Integra- any rear disc equipped model.
99-00 Civic Si

you will again use the entire setup. EXCEPT!! you have to use your stock lca's or aftermarket ones for a 96-00 civic! the Integra or previous year Civic ones are way too short. you will end up with extreme positive camber if you try. so please don't. also, it is not necessary to upgrade your master cylinder or prop valve. they are exactly the same as 99-00 Civic Si( same part number also) you can upgrade the master cylinder if you would like to get some extra braking force,but it is not necessary.


FOR 99-00 CIVIC:

88-98 Civic-any rear disc equipped model
90-01 Integra- any rear disc equipped model
99-00 Civic Si

the above info for 96-98 goes true for you also.





FRONT BRAKE SWAPS: WHAT YOU NEED..........

FOR 88-91 CIVIC:

88-00 Civic- any model
90-01 Integra- any model
91- present NSX- any model (requires some significant modding)


FOR 92-95 CIVIC:

88-00 Civic-any model
90-01 Integra- any model
91-present NSX-any model (requires some modding also)

FOR 96-00 CIVIC:

88-00 Civic-any model
90-01 Integra-any model
91- present NSX-any model (once again requires modding)



that's pretty much everything that i have ever messed with or know something about. i have also been told that you can use newer EP and RSX brakes also, i don't really know much about it,so if someone can confirm it, go ahead. once again, i'm tired today, so if something is incorrect correct me. thanks for looking.


96-00 civic cx prop valve is the same as the si one.


the other ones are different. :)

[Volume 8]

found this on G2IC, due to the usual honda interchangeability i'm pretty sure this will also work on civics.

[crazyxzer0]

has anyone talked about the differences in Ebrake cables.. I'm curious what ebrake cables can I use (93 ex coupe)

[ronjdm36]

i used the stock gsr cables on mine, there were two mounting tabs that came up a little short, but other than that they worked fine.

which two mounting points were short?

[angrychicken]

When swapping out the master cylinder should you also swap out your brake booster? I'm trying to work out a deal with a friend right now for the rear disc swap myself. My car is an Ex, is the GS-R booster larger?

[crazyxzer0]

We have a 7/8th master cylinder. In the event of swapping out a master cylinder for a integra MC, you need to swap the integra brake booster too. I believe if you do swap you need Non-ABS MC and BB because of the brake lines do not line up correctly.


The other option is to get a 1991 Civic EX 15/16th Master Cylinder. that will match up with our booster and fit perfectly.


Hope that helps man.

[jdm93EJ1]

for the front Integra calipers on a 93 EX do I need a whole new knuckle for the caliper? or can I use my stock one?

Adam

[angrychicken]

Back to to Booster and M/C, can this be taken off any Teg, or is the GS-R preferred? There are plenty of DAs @ the local wrecking yard, but no newer tegs.

[Dina]

Ok so I am getting a 93 si rear disk brakes complete with everything will all this fit my coupe with no problems? cables lines ect.

[Volume 8]

yeah edwin, it should bolt right up. if you need help with any of it let me know, i'd be glad to help.

angrychicken:the DA master cylinder and booster will work.the gs-r MC may have a larger piston but i'm not sure on that.

[crazyxzer0]

Back to to Booster and M/C, can this be taken off any Teg, or is the GS-R preferred? There are plenty of DAs @ the local wrecking yard, but no newer tegs.



M, you need a NON ABS mastercylinder/Brake Booster... so that means if you are running an integra one it will be from the Integra RS.

if not and you want a bigger M/C and keep your stock booser, 91 Civic EX MC will work. I've HEARD that the 89 accord M/C will work as it is 15/16th too but I can't find the confirm information anymore. I'll research more.



As for ebrake cables. I found a nice discovery.


4door Integra cables will work perfectly with the coupes.

As for the ebrake cables from Civic and Integras, they will both be too short but it can work if it is not in the stock location (ie. some bolts wont line up)

[havok]

Is 91 Civic EX the one with d16a6 engine? Chassis code ED4? If yes - is it possible to get MC form other 4th gen Civics with the same engine, like ED7 or EE5?

What is EJ2 MC size?

[crazyxzer0]

The master cylinder needs to be the 91 civic EX as it is the only Civic with integra size's brakes and rear disc brakes.

Stock EJ2 M/C is 13/16th.

Stock EJ1 M/C is 7/8th.

[black93si]

OKay. its called a platform for a reason. meaning that its all the same from the front wheels the back wheels all civics and integras are the same track and wheel base. ex for the harware like spindles control arms and so forth. wich are only chaged to make up for weight difference or trim.

gsr booster wont fit

[Dina]

Ok so a buddy of mine at work gave me some 95 integra Rear trailing arms with everything except the brake lines and ebrake cables which ones do I have to get to make this work for me?

[Volume 8]

99-00 Si cables and lines should work, also 94-01 integra cables may work.

[Volume 8]

Ok, so today I found out that DA front knuckles will not fit on an EJ2. There's too much of a bend in the upright so it hits the spring.

[SLVREJ8]

On 96 to 00 civics you have to change the proportioning valve not matter what if you are swapping to disc. The amount of fluid sent to the back is different for drums than discs. As for the master cylinder it is only the same for EX and SI's.

[JdmRevelations]

ummm not really on the prop valve... im running mine with the stock EX one and brake without any problems...

[crazyxzer0]

ummm not really on the prop valve... im running mine with the stock EX one and brake without any problems...


for daily driving, its fines.. when you start road racing or what not, the stock drum propvalve forces the fluid to go to the drum first which results in the rear locking up before the front..


Swapping to a 96-99 CX or 99-00 Si prop. valve when installing rear discs.

The 99-00 Civic Si comes with the same shaped proportioning valve as any 96-00 Civic, so swapping the proportioning valve is a bolt on job, which can be done with a few offset brake line wrenches. The stock drum proportioning valve, when the brake pedal is applied, sends fluid to the rear drums only. This is because the drum shoes are a few millimeters from the drum, so the fluid initially moves the pads to touch the drum, whereas with a pad and rotor, the pad is so close that it brushes along the rotor while driving. After the shoe touches the drum, the proportioning valve sends fluid to the front calipers as well, and then acts as a hub for the fluid. So a rear drum intended prop. valve in a car with four wheel discs is not the end of the world.





this will help those w/ EKs... and there is some information that can be transfered to the EG too.

[SLVREJ8]

The last thing I want to have to think about is if my brakes work propoerly. So when I did my swap I changed it to factory specs so that I don't have to worry about the wrong end locking up at the wrong time and getting me into trouble. It's not that I'm right or you're wrong or vice versa, I just think about it as a safety issue.

[ronjdm36]

agreed, i have even been told by a reliable source, that the standard civic prop valve is the exact same part number and part as the EM1's

[SLVREJ8]

when I did the swap I looked up the part numbers to be sure and they are different that's why I swapped the prop. valve

[crazyxzer0]

agreed, i have even been told by a reliable source, that the standard civic prop valve is the exact same part number and part as the EM1's


96-00 civic cx prop valve is the same as the si one.


the other ones are different. :)

[smo_ej2]

i have a question conserning my future EK.

(i'm getting a -00 ek, 1.4 liters)
it has ABS and i'm guessing it has rear drums?
so in order to get it passed on the tests (after putting in a new engine) i have to swap the brakes.
i'm thinking about getting 'em from an integra with all 4 discs and with ABS.

what do i need, will the ABS work?
actually ANY info on this would be great :TU:
i dont know sh1t about ABS.

[Dina]

it would only have abs in the front as long as you keep the same axles and the knucles you will be ok the knucles have the sensor and the axles have the ring on them for the sensor!

[smo_ej2]

ok, so why wouldn't the rear work?
if i take everything from the integra?

[crazyxzer0]

abs is not implemented in your car for the rear. as drums dont have abs.

[smo_ej2]

ok.. that means i just have to tear everything off of the car, and start installing them from scratch. it can't be that hard, can it ;)

[STN_DX]

So for me to swap it is recommended to switch out the proportioning valve if I am putting an Si rear discs on my 97 DX coupe right? I can use the one that the guy is running currently? This swap is coming off a wrecked EK hatch. Goin to try and attempt this swap this weekend.

[mphscivic]

Does anyone have or know of a write up in swapping 99ex drums to disks?

[Volume 8]

So after hearing about being able to use a 15/16th master cylinder from an 89 Accord or Prelude Si and looking at pictures and comparing part numbers, I was finally able to get my hands on one. Just like I thought, it bolts right up with only a minor issue with one of the lines. The fitting in the front is straight out the side instead of being at an angle. So I just bolted that line on first, bolted up the master cylinder and then bolted up the other line.

[Dina]

Not sure if this has been posted but I know this thread is very helpful so here it is. I found this in an article on Honda Tuning June 05.

Ok this is what I found from the magazine. Any 88 and up civic and 90 and up integra can do this. You will need the knuckles from any dc2 integra or an eg/ek ex or si model.The calipers are from a 93-95 legend coupe also the ones from a 94 95 legend 4 door gs will work. The legend calipers are the same as the nsx caliper with the difference of the nsx being made out of aluminum. Both calipers have the same bolt pattern and share the bolt pattern with those from the 98-00 Accord v6, 97-00 Prelude vtec and ITR. The 11in rotors and calipers need more space under the wheel than the stock ones, so 15 inch wheels will be needed.

[Dina]

Will 95 civic ex coupe with rear disc brake ebrake cable work for on a 93 civic coupe ex with 95 integra rear trailing arms?

[GarageBuilt]

anyone kno what modifications need to be done to use nsx calipers?

[GarageBuilt]

Will 95 civic ex coupe with rear disc brake ebrake cable work for on a 93 civic coupe ex with 95 integra rear trailing arms?

i thought the ex rear rear trailing arms and the 95 integra rear trailing arms were the same? im going by hear say but i thought coupe ebrake cables fit coupes but hatches were to short. coupe cables will fit hatches but u have to run them different because there longer. im not 100 percent positive but yea!

[mARTYR]

alright...im reading a lot of mixed info so i want to get a few things straight before i attempt it this week... so i have a 96 dx and i already got the trailing arms,cables and all that.
so do i need a si 15/16 master cylinder and booster right??? on the first page it says their the same part number but is that for the ex model only?
and the also ill need si valveing...50/50 right?
can i still mount everything up and be fine to drive until i get the m/c and vavleing? o yea and also will the drum set up hardware fit right over or will i need new bolts and all that?

[mphscivic]

I would definitely change the prop valve to an SI. I didn't change my M/C and I'm just fine. You can reuse all the bolts with no problem. They are all the same. Be sure you have e-cables and rear brake lines for an SI. What year and model did the trailing arms come from?

[mARTYR]

its all came off a 94 coupe si..i think..that wat the guy told me

[TwoToes]

I noticed it wasnt listed in the original list on the front page. What has the same front calipers as a 00 si?

[Speedy]

a 96+ ex...i have 97 ex brakes, same as si

[spadam]

a 93+ ex...i have 97 ex brakes, same as si


and dc/db (non R) tegs, and dohc del sols

91 ex's and da's also had 10.2" fronts, can't remember which caliper they used though

integra and civic calipers are different.


Si will be classified as Civic calipers. Also oddly enough my 93 civic calipers pads do not match the 94-00 civic ex/si front calipers and it doesnt match integra ones either.


All rear calipers are identical from 92-00 civics and 94-00 integras.confirmed. not sure on 90-93 integras though and 88-91 civics.

Interesting. I'm running front calipers/brackets from a DA on EJ1 knuckles. Obviously they bolt up but I'm also using pads, lines, and rotors for a DA.

I meant that they are not same caliper.. mounting points are identical though.

Pads are different on the calipers. sorry if i was confusing haha.

Oh man, i had alot of issues when it comes to brakes...i didnt want to get stuck with brake pads for the wrong car.


I researched ALOT on brakes before buying :). I used a honda parts catalog to verify part numbers as well as brembo part numbers for selective calipers on different cars to come up with what I needed.

[lastresort576]

Well i am going to add to this a lil bit.

if you get the 15/16'th master cylinder to mount up to you existing brake booster, where the master cylinder is coming off a 88-91? prelude or 4-dr civic with 4-whl. disc's(lionel jump in on year facts)

so this means that the 15/16th MC will fit/mount onto a 13/16th booster.

BUT, unless you have the upgraded brakes from 9.44" to 10.xx" you will not want to do it.

today i swaped to a 15/16th MC while still utilizing the 9.44" brakes and i shit you not, as hard as i pushed on the brake pedal i could not get the car to stop in a timely manner, nor lock up. Sure the pedal feel was great, but i just couldnt get the car to stop.

so until you switch over to some bigger brakes just stick to the 13/16'th if that is what you are currently rocking.

i now have in my collection of MC's/Booster's

2- 13/16 MC's/Boosters (although i believe 1 is junk though...)
1- 15/16th MC
1- 1" MC/Booster

yup my parst collection grows!

[crazyxzer0]

did you bench bleed the master cylinder?

Also do you have a 40/40 prop valve?


My car felt like ass until I removed my master cylinder and bench bled it as well as adding the 40/40 valve. Now it stops damn well :)

Course i do have.. an 93 EX booster + 15/16th from 91 Civic EX MC.

[naman]

With my brakes I went from 9.xx to 10.xx
The willwoods are 11.75" and are designed to work with a 15/16" or 1" mc.
I swapped boosters to fit the new mc. Pedal is good and I can lock all 4.
Haven't tried a 15/16 yet but feel is supposed to be better.
Prop is the same on drum ej7's as on em1's so no need to swap it.

[spadam]

Lastresort, that doesn't sound right. You should have a harder pedal with the bigger master cylinder. Did you also check the linkage adjustment between the booster and the mc?

The only other possibility I can think of is that your booster is smaller and isn't giving you enough assist....

[naman]

Yeah the teggy booster I is way deeper than my stock booster. And I had to adjust the pedal rod out some.

[lastresort576]

i did bench bleed it and i do have a 40/40 prop valve. ever since i did my rear disc. conv. a few years ago ive never had the greatest pedal they always need to be pumped at least once b4 its pretty firm also the pedal is firm in the higher rpms...since then ive bleed the brakes numerous times. but no matter how many times i bleed the brakes it still feels like air is in the system. however i do not leak any fluid. i think i need to get a vacuum bleeder and have it on stands at all fours to get it right...just a thought though.

spadam, when i put on the 15/16th MC the pedal feel was hard. harder infact. prior to me installing it, as a result of me doin the wheel bearings and not disconnecting the calipers the pedal went straight to the floor...? so i bench bled the 15/16th mc installed it and the pedal was so firm i didnt even have to bleed the brakes. took for a spin and from about 15mph'ish slam on the brakes as hard as i could, it should stop instantly it still took like 15-20 or so feet.

so i pulled off the 15/16th, threw on another 13/16th i had from my parts car and i can at least press the pedal now w/o it goin to the floor and stop the car to an extent, but still feels mushy and wont lock up...and i dont really trust them too to much right now if i was on a 'fun' road. normal roads w/o playing its fine but still...

pads: hawk hps or + (the box said hp+, the pad shim said hps...w/e)
rotors: Brembo blanks.

[naman]

Try a new booster sounds like your has had it, more vaccum at higher rpm so the pedal is better.
What front calipers?
Rears?

[lastresort576]

rears are nissin's from an eg6

fronts are the..akabota's? stock s/si sol ones.

so possibly the booster? i was wondering this b4...if i swap the booster to a good 13/16th one, will i be able to utilize the 15/16th MC? or not.

[spadam]

As long as the bolt pattern is the same, you should be able to swap it. If the boosters are different sizes, there will be a difference in the amount of power assist they provide, but it should be rather negligible. Technically a booster that offers less assist may cause you to interpret a softer pedal, but its really just that your foot is picking up the slack that the vacuum normally does.

The reason your pedal initially went to the floor after you put your car back together is because you had to spread the calipers to get them off and, more than likely, you stretched your lines around and what not working on the car. That was just everything returning to its default position in the whole system. It doesn't take too much extra clearance at the caliper to send the pedal to the floor, especially if you consider the motion ratio between the pedal and the caliper under normal conditions. When you stop the car you push the pedal through a range of about, say, 2 inches to get a total motion in all four calipers of maybe 1/4 inch. Thats an 8x ratio, so imagine if you actually have 1/4 inch of clearance at each wheel... the pedal is gonna move 8 inches now, which equals floorboard.

[lastresort576]

alright ill see if changing the booster will work. and yea the bolt pattern's are the same. i would have thought that the boosters would be the same but they do have diff. color tags on em. the one on the car is yellow, and the one i have kicking around is green.. idk if this means anything or not..

[naman]

Idk my 1" mc used a different booster for a mid 90's odyssey or 98+ teg w/abs. The bolt pattern is wider than the 13/16 I had. I think you can get 15/16 in the narrower or wider bolt pattern on honda boosters like the one you have.

[lastresort576]

the 15/16th MC's on tegs use a dif booster like one of the 1" mc

the 15/16th's from the old preludes and old 4dr. civics with 4-whl. abs have a MC that fits on the 13/16th Booster and does not require changing of brake lines like the tegs 15/16th and 1"

ive got the 1" MC and Booster as well but i dont really feel like re-doing the lines atm. which is why i opted for the prelude 15/16th MC originally.

[naman]

Yeah and one of the front line has a different size fitting too. I cut and reflared the front line a rebent it a little, the rear threads in but I had to re-bend it too much or bending on the rear because the exit on the mc is on the divers side not on top but all togeather it only took me like 20 min. I got lucky no leaks and the old line reflared ok.

[B18C Inside]

I'm wanting to attempt this conversion. How difficult is this swap? I have a 98 EJ8.

[spadam]

Its real easy, only a few nuts and a couple of flare nuts, get yourself a couple of double ended flare wrenches from sears (10mm/12mm and 13mm/14mm or something like that) and you'll be set to do any lines on your car. You alsoneed a buddy to pumpthe pedal for you when you bleed your lines at the end.

The master cylinder probably isn't gonna fit. I'll figure it out and put some pics up in a bit.

Btw the honda p/n for the 46100-SH4-A11

[B18C Inside]

Thanks. PM me if you can.

[ej1MD94]

I recently bought a wrecked em1 and I pulled the whole braking system off the car front rear MC and prop valve...anything that I need to know before doing the swap would be appreciated.
