i fixed my brakes, but they dont want to grasp hard at the end... when i want to brakes fast/hard, i press the pedal down but it just slows me down a lot and keeps rolling and finally stops.. the pedal isn't going all the way down either, if i drive too fast and try to brake quickly, my car wont stop and i will hit the car in front of me... so i've had to brake like 7 feet before the car in front of me in order to stop on time.. what do you guys think is wrong? please help me out as soon as possible because this is dangerous, specially since its raining a lot right now in SoCal.. thank you

 

sounds like your sliders are siezed to me. that or rebleed the system there could be air/water/dirt in the lines.

 

ok so rebleed it the whole system? including brake lines on the master cylinder?

 

Why don't you break it down some more and tell us EXACTLY what you did?

 

I think he meant just rebleed your brakes at the calipers/drums in the proper order. Do this with the reservoir cap off.

 

Check the brake booster:

 

well i recently replaced the master cylinder, bench bled the master cylinder, bled the wheels in order, then bled the lines that connect to the master cylinder... then they didn't feel right, so i bled the wheels once again and they still feel the same... so that's where im at right now.... and well i haven't done thew check valve test on the booster.. but im pretty sure that its good.. i mean while the car is off and i press the brakes about 3 times, they get very hard... so its working, and when i keep my foot on it and turn on the car, the pedal sinks in.... so what do you guys think? because if it is the booster... how much is that gonna costs me? because im on a very tight budget right now... thanks for the replies

 

when you said turn the car on are you starting the car or just keying it on??
