aight guys before you start with the "use the search button comments"...i already did sereral searches and still havent found the solution to my problem.

well here it goes...
i have a 93 CX hb (non-abs of couse) and i did an upgrade to a 97 integra master cylindar and brake booster. i already re-aligned and flared the brake lines that lead to the MC. everything seemed to work out pretty well and line up pretty good. so i take it for a test drive and everything seems okay. then all of a sudded it feels like the brakes locking up. so i turn off the car for a quick 5 seconds and its back to normal again...then after a little bit it feels like it locks up again.

I DID A SEARCH and read up on several different posts that seemed to be similar to my problem but im not sure about some of them. i know there have been people that have done the same swap successfully w/o having to do any modifications. there were posts about shortening some push rod but how would you go about doing this??

if anyone has done this successfully please give input on what all you did

 

Are all four brakes locking up?

What brakes do you have on the car?

If all else fails, I'd try to reseat the calipers (or whatever you want to call pushing the pucks in so they "reset" so to speak) and then try it agian.

EDIT: You can adjust the brake pedal up, that may be part of the problem as well.

 

sounds to me like you upgraded the mc/booster *WITHOUT* actually upgrading the brakes. Are you still on the stock rotor/drum setup? If so, thats your problem...

 

I think it has to do with the booster. Did you adjust the brake rod that connects to the the booster? (the one the passes through the fire wall) Sometimes you will have to adjust the rod. I thing you have too much preload. check in a service manual.

BINGO! I'll put my money on that as a solution.

it sounds like this is the problem.

if you upgrade the m/c and booster which is a 1 in setup i believe and still have the stock CX brakes that is why you are locking up. too much fluid pressure for the puny calipers and drums in the rear. you need to at least upgrade the rears to discs and possibly the fronts to gss brakes as well.

 

i have integra brakes all they way around...what moron would upgrade MC and BB without upgrading brakes first ...for some reason i have a feeling there are some that have done that before. well i just went back to stock MC/BB setup for now til i figure out what the hell is best for me

 

i think i might have a faulty master cylindar beause when i pulled the brake liines off nothing drained out of the cup

 

my prelude does that too. its the booster.
