I'm having a problem w/ my brakes the pedal goes all the way down when I try and stop. I knowit is somthing to do with bleeding the brakes. But I don't know how to bleed them on the S4. from what I hear it is different from the A4. It's not the normal way to bleed them. ( pumping the pedal ) please help!!

 

Idk you mgiht be right , however when i re did my brakes about 3 months ago all we did was bleed them regularly with the pumping method and i have no hicups yet.

 

Just the normal brake bleeding procedure works fine.

They don't just go to the floor. You might have a bigger problem. Your master cylinder might be going out, or you might have a leak in the system.
How much fluid is in the reservoir?

 

I'm pretty sure there's a right up about it on audiworld. That's what I used a while back and it solved the problem when my fliud went too low because of a bad rear caliper.

 

2k's right sounds more like a master cylinder piston seal issue if it just happened all of a sudden

 

If it has to do with bleeding your brakes, get your hand on a power bleeder.
you'll be able to do it all by yourself. Check on ECS tuning .
Good luck

 

took it to the mechanic and he couldn't bleed it at all he tried like 3 different ways. He said it's the master cylinder. So I ordered it off ECS today. W/ over night shipping it is still $40 cheaper then audi!
