B18C5-EH2

Here's the order I'd take if I wanted greatly improved braking:

1. 94-01 Integra front brakes- get the entire knuckles and just swap them over. Knuckles include the spindles, calipers, brake lines, brake pads (change them), and I guess that's it. Simply undo the upper and lower balljoints and the steering tie rod end joint, and pop in the Integra spindles. Make sure to realign your car though since you are undoing the sterring tie rod end - this controls your toe in your alignment.

2. Add this 1991 Civic EX 4-door master cylinder that I'm talking about and you're set.

3. Add whatever brake pads you want to. I won't recommend any in particular because there's just too many and different people need different things out of their brake pads.

By simply changing the front brakes to Integra-spec and adding a bigger m/c you will notice a huge difference over stock brakes.

4-wheel discs are nice, but they are not mandatory if you want to stop better. If all you did to your car was add the rear discs w/o changing the front discs you'd be sorely dissappointed - it wouldn't stop any better really. 4-wheel discs are for those who have bigger brakes up front and want a better braking balance - I'd even say it's more for those who enjoy hard driving in corners.

If you do end up adding the rear discs, then I'd also say you must add a prop valve from a 4-wheel discs car to. The proportion valve controls the bias in terms of fluid to the front and rear brakes respectively. Why would you want rear discs and not get a prop valve meant for rear discs?

Anyways as usual I'm ranting...

B18C5-EH2

I'm pretty sure there is, but I'm not sure enough to even take a guess. I try not to talk about stuff i'm not sure of, so as not to contribute to any misinfo around here.

acura_typer

I must say this is great info. Much better than the meaningless bickering that goes on here usually.

I would like to add that if you do decide to upgrade the booster and M/C to integra ones, get 98 and up. On the older m/c you have to cut the line and install a larger fitting, and reflare the end. With the 98 and up, you just have to bend the line around a bit (make sure you use a pipe bender or you will crimp the line), and bolt it in. Good luck doing anything with the booster if the motor is installed. You may have to remove the intake manifold to get the booster out.

Hooch'n

Yep, going to junk yard down the road and getting some goodies off a 98 Integra LS.

B18C5-EH2

Hey man, the LS is also ABS, meaning that you will go through the trouble of having to double flare that line closest to the firewall.

Why go through that trouble if you don't have to?

hondaeg5

do the vx and si have the same booster? i know the m/c are different.

shawnhayes

If you don't have the calipers to need the bigger fluid movement, why would you want to upgrade to a larger master cylinder that would DECREASE the amount of hydraulic fluid pressure you can generate?

This is something we frequently forget. The ONLY reason to upgrade to a bigger MC is to get more fluid volume supplied to those bigger calipers we all like to install.

The 1" master cylinder may be needed for ITR calipers (and the do it yourself Accord Wagon ITR spec upgrade), but is overkill for the GSR, LS, or ex calipers.

why not use a 89 prelude master...its 15/16 and fits 88-91 civ/crx without changeing the booster,won't it fit 92+

B18C5-EH2

Well then buy one and fit it up and tell us how it works out for you.

I'd like to know for sure that someone has done it and it works. I just told everyone that I've personally done the 1991 EX one, so we know it works now.

89civicdx

I use a 89 prelude master cylinder on my 89 civic its 15/16 and fit fine.I originaly bought a 91 teg cylinder but found out that the bracket didn't line up with the booster. The prelude master cylinder fits my 89 with no mods to the brake lines. I don't know if 92-95 civics use the same master cylinder bolt pattern as the 88-91 civ/rex but if they do then it will fit.

Check the EF forum I'm sure there are more people then I that are using the prelude master cylinder.

How does it work...on the track it worked good but I couldn't really tell the diff between a new 13/16 and a new 15/16 >with teg brakes.

I changed it a while ago so I unfortunately don't remember the exact year but I believe its a 89 or 90MC.

i'm doing GS-R brakes on my 1992 CX (the front & rears). i'm very interested in doing this M/C swap from the 1991 Civic EX because there's no pipe bending involved. so what about the proportioning valve? what prop valve out of what car would you (Tom) recommend for use with the 1991 Civic EX M/C?

thanks very much for the info from this thread

BROOD

91 EX MC installed........now tried. Very good investment of $85 for me.

stevel

Good info B18C5-EH2. It just blows my mind how people are like "wow, thanks for telling all of us!" Every time I see a big brake post I tell people to use the 91 EX MC and it's a straight bolt on and it just gets passed right over. The very next post someone will put, "Use the Integra RS MC and booster and you're set!" and then someone responds to that one and says thanks. Just amazing. Brian from Fastbrakes told me which one to get when I ordered his 11" civic upgrade kit. I've had mine on for almost 8 months and that MC and big brake kit is the best ~ $350 i've spent on that car. In fact I think I've posted in a few threads that you (B18C5-EH2) have also posted in on the topic of bigger brakes and MC upgrades.

By the way, the 91 EX 4 door has the same engine as the Si. I got a rebuilt MC for $55 from an Autozone.

ok... i need brakes really bad. so im gonna get a 15/16th m/c from a lude or 91 civic (should be same bolt pattern).... look into gsr/ls front brakes.....

would i need a '40/40 prop valve'?? if so, what car? model, etcc..... TIA

EG*MonKEY

if i wanna change my brakes t larger brake what items would i need someone please give me a detailed list........i have a 92 civic hatch dx thank you

I have a 93 Civic EX Coupe and i'm looking to swap in GSR brakes soon. i heard the GSR brakes will bolt right up and the 91 Civic EX 4-Door 15/16 M/C will bolt right in too. is this all i need in order for it to work properly, meaning no unneccessary lockups and such?

ace1875

This is for just rear conversion

nice work

Kev95lx

True, but I personally prefer having my 1" MC and the booster that goes with it from that car..the way I see if, is that if Honda put it there..you should use it.

Thus, the 1" GSR M/C & Booster, 92 Civic Si Prop Valve (4040) with my FastBrakes kit setup in my car..

deviant94ex

so my 94 ex coupe with rear drums and no abs has the 7/8" master cylinder stock. will this 15/16" 91 civic ex one work for this as well, or will i still run into problems. for that matter, is it necessary to even upgrade since i am slightly larger than the 13/16" ones already? all i would then need is the 40-40 prop valve.

speaking of the 40-40 prop valve, which one would i get so that there is no rebending or flaring of lines for that either?

finally, for gsr rear brakes on my 94 ex coupe, what paring brake cables would i get? i need to email larry at import auto salvage for them but need to know which ones to ask for first. thanks for all the help.

For Shawnhayes and Todd, or anyone else who knows.

Here is a question that is often ignored. Boosters. The MC decides the volume of brake fluid, the proportion valve decides how much goes where, the booster does ?

I am currently running this set-up on my 92 CX hatch:

94 Integra RS Master Cylinder (third MC I've used)
94 Integra RS Booster (third booster I've used)
4040 prop valve
Fastbrakes 11" Wilwood Dynalite calipers, two piece rotors
ITR rear calipers and redrilled disks

Problems are, rear passenger brake locks up all the time. (may need to be rebuilt, slide pins are good)
This is the problem I'm asking about, the brakes fully engage within the first 2" of travel. Not very good for modulation on a track, there is pretty much no room for error, brakes are on/off. Bumps in a braking zone make for exciting times

So, if I go back to the STOCK CX booster, but with the 91 EX 4 door MC, will I get more pedal travel? Would the brakes be more progressive? Lastly, will the booster be enough to supply boost for the above set-up?

I've went through three set-ups (booster and MC) on this car. Stock was too small, ITR set-up was way too much...on the test drive the brakes got tighter and tighter till I came to a stop right in the middle of the road! My current set-up is described above. I'm getting sick of these brakes! Any help would be greatly appreciated!

Hi, guys another master cylinder that will fit 88-95 civic, CRX, del sol without modifications is the 88-89 Integra master cylinder, 90-91 ex master cylinder will fit with no mods either. As for using a 2000 si master. It won't bolt up. You would have to change the booster to the Si one. As for putting on GSR master+booster, you don't need to reflare anything just bend the lines with caution and it will bolt right in. It's really easy. And it gives you great braking power. As for the guy with the 93 EX that wants to upgrade his brake to GSR. The front brakes on your EX are already GSR brakes. So it really won't do anything to do that on your civic. I would get the GSR master+booster. In my opion this would be a great brake set up

GSR brakes (front)
rear disk
steel braided lines
GSR booster
maybe cross drilled rotors
EBC pads

Just my 2 cents

i found them for 51 bux re-man'd

Anyone have any ideas on this?
