Ok here is my dilemma. When i was going home yesterday
i noticed that after i stopped at the light my brake
pedal was slowly but surely going lower and lower.
I can still get the pedal back up if i pump it, but
again it will go down very slowly. Can someone please
help me with my problem. How do i fix it?

 

Sounds like the master cylinder is going

 

Do you think it could be the brake booster?? or is the
Master Cylinder that makes the pedal do that when it
goes out? Also could i just go and purchase one from
the junk yard and stap it on? Any help is really
appreciated, becuase I hate the way my brakes feel.

 

I second that. DEFINATLY the master cylinder. I know because i just replaced mine about month ago. You can get one from a junk yard, just press the pedel and test it beforehand. I got mine from Pepboys, and it cost me $50 + $15 core charge. Actually, they didn't have one for an SI model, so i took a chance and bought the non-si one. Turns out the only difference is that the SI one uses a bigger cylinder for better stopping power. Either one will work though.

 

most likley its the seal in between the booster and M/C....but since you are doing it, its best to upgrade to a bigger M/C ie. 90-1 prelude Si or CRX Si (90-1)....they are bigger....so it might help a little also....

 

So do you guys think it's the brake booster at all? Or
just forget about the brake booster and replace the
M/C. Would i need to get a seal like (eg6ajk) said?
Sorry for all the questions, but i want to make sure to
do it right.

 

Like i said, its almost definatly your master cylinder. Real simple way to find out. Press the brakes with the engine OFF. If the pedel still goes down slowly, its the master cylinder.
