My Brakes
|
Sign In

So, I have this 1980 Audi 4000. The brakes recently started acting up. Like, when I was stopped at a light I would have to push down so far to stop but then it would get farther and farther as I was stopped. Then they stopped stopping. Its like...I have to push REALLY hard to make the car stop. All the way to the floor. All the pressure seems to be gone.
We drained the brakes and my brake pads are fine, as is my brake fluid.
Has this happened to anybody else? and any suggestions on what else to check?

Hi
Has the entire system been checked for any leaks?
Definitely sounds like a hydraulic problem.
Why were the brakes "drained"?...I assume you mean bled.....was it for this problem?
CAn you pump up the pedal ?
What I mean is,if there is no leaks at all and the linings are ok,try pumping up the brake pedal and see if it firms up,if so,let off and reapply,it will probably start to go lower again...
Sounds like the master cylinder is faulty...has the symptoms of that....from what you describe..
CAUTION: DON'T CONTINUE TO DRIVE IT IN THIS CONDITION...IT IS UNSAFE ...

Yeah, I totally meant bled! :)
I don't know about the leak..i'll have to get that all checked out.
But if I pump the brakes they firm up for a few seconds. However, they go right
back down. Thanks for the caution. I was kind of hoping for more of a "Oh! All you gotta do is kick the car and it'll work!" but, thank you! I'll get all that checked out. :)

Yep
Sounds like a bad master cylinder. But get it checked to verify no other leaks...
"So all you have to do is replace the master cylinder, bleed the system and THEN KICK THE CAR...LOL "
Let us know...
