sounds like m/c. The spring in there may have crapped out. Also check the
brake pedal spring. Check the distance between the brake servo flange and
clevis hole in connecting rod end, it should be 9.8 in. Rebuilt m/c's are
cheap...new OE units are better and aren't too much...around $100....at
least cheaper than rear calipers...[Audi says m/c's can't be rebuilt].
Also you might have some issues w/ the power brakes. After you shut off the
car, the pedal shouldn't get hard until you've got 10-20 pumps out of it.
The bombs often go bad and the servo can too, but no power brakes just
requires more effort to stop the car, but the pedal shouldn't go all the
way down or not return all the way. good luck.
