i had a problem a while a go that when i press on the brake the pedal goes to the floor and the brakes hold a little bit and when you are in traffic the pedal does the same thing and the car keeps moving foward and u have to use the handbrake so the car won't move foward. so i decided to get some new brakes i got some new rotors cause they were due for a change i got some drilled and slotted brembos and some ceramic pads, i also drained out all the brake fluid and cleaned the master cylinder container with some brake cleaner and let it dry and refilled it and bleed the brakes and it worked good for the rest of the day then i drove it. i aint drive it much between then and now but my aunt drove it quite often and she said it started doin the same thing again. can some one tell me how to fix this. please

 

You got a leeky wheel cylinder....

 

ok so does that mean that i have to get new calipers

 

We had the same problem in our tl, took it in got the master cylinder replaced, and then it workd and then didnt. it is still on the verge of not working we have no clue what to do..... it is a great car when it works...

 

hey im starting to have that same trouble since i was drivingfast and hardbraking to often you know i was taking some corners at hihg speed like if i where racing and braking strong too often so my brakes overheated and i was unable to break gently but to brake harsh almost locking the wheel, since this im havig that problem that when i step on the brake it touches the floor i think it could be the brake pump or something, mty car stops normally so i dont have tyo use the handbrak but it is not stoping as good as it used to

 

Check all wheels' calipers. if one or more are leaking - you found the problem. If not - check all brake lines for leaking. If not, than only the master cylinder left

Good luck, Misha
