Ok So I searched found some help... but Just would like a lil more Ill thank ANYone who responds in advance..

Ok I have a crx si 89... I just swapped the motor from a zc SOHC to a zc SOHC VTEC... basically a jdm z6... anyways... After the swap my breaks were FUCKED!!!!!
So I bled all four of em and NOTHING.... We never touched the brakes during the swap... but at one point I was pressing the pedal hard...
I also filled the fluid... bled it filled again.... didnt help... I read that maybe my rotors are warped? But I dont see why if they were FINE before... thats all I can think to say right now but thanks for looking

 

Bump for some help

 

Just a guess but since they are vaccum assisted then maybe you have a vaccum leak or the booster is not connected right?? I really can't think of another reason they would be hard to press (I assume the car is running when the brakes are hard to press?)

 

yeah of course...
hmmm Ill look into the booster and the leaks thanks...
can warped rotors do this?

 

you probably messed up the vacuum to the booster somehow. (did you reverse the checkvalve???)

has nothing to do with warped rotors...

Brake booster uses engine vacuum to assist the pedal. Warped rotors would make the steering wheel shake under braking. So like said above, either the line going to the booster is bad, or the booster itself is bad. Most likely the line or check valve is bad.

 

Sweet thanks guys ill check that soon

 

Sounds like the booster, mine was bad and it did the exact same thing along with giving me an idle surge. if you swap it out go with a DA brake booster and MC.

 

im with him^

 

okai thanks alot but what exactly is an MC?

 

als what year integra? I think ill get it from autozone... it is a direct fit right?

 

MC = master cylinder

THe thing that is bolt onto the booster and that the brake lines go to.

DO NOT buy an integra booster/mc unless you have some sort of bigger brakes or are planning to get bigger brakes, there would be no point.

However, if you do have bigger brakes than that of stock, by all means, get the integra booster/mc.

90-93 Acura Integra I believe. GSRs were from 92-93. I think the LS has the 15/16'' MC as well.

 

ooooh lol master cylinder haha Im not familiar with all the abrv's yet thanks though

 

bump I fixed it yesterday turns out when we swapped the engine... we changed a tube that goes from the IM to the booster to a steel braided one... and the little off white adapter piece that goes into each tube... was backwards... its the little piece that you can only blow air through one side.... Im sure I just confused the hell outta every one but thanks for all your guy's help

PS heres a non detailed pic it is where the two tubes connect right above the master cylinder

Like i said earlier, the one way check valve. Glad you fixed it.
