ok i have an 89 crx si, a few months back like Nov. i put in an LS motor and right after that i have had nothing but problems with my brakes. when i go to slow down i have to stand on the brakes literally just to slow down. and when i am at a light the pedal slowly goes to the floor. also i got a new BMS put it on bled front and rear and the problem still persists. I have no leaks anywhere and no air in the lines.

so my question is could my LS swap possibly of screwed the BMS up? ( i have asked others and they have said no)

and also should i change out the brake booster just incase, if so the bolt on the top left side i cannot get to it to loosen it ( i have tried everything i myself can do)

so can anyone offer me some assistance please.

 

Its not your motor. I had the same problem with mine a while back of the pedal sinking to the floor. That usaully mean syour BMS is out and you need a new one. Its weird you got a new one and the problem still presist. I say take it to honda or something and have them check it out. Maybe have them bleed the brakes just in case.

 

ok well hopefully i can have this crap fixed here soon

 

buy a one man bleeder kit from autozone, 6$ and it will make bleeding breaks so much easier for you.

after i changed my mc the breaks would still go to the floor till i bought the bleeder kit at after that they worked great
