strange brake problem
Can anyone suggest a cure for my UK Audi 80, I am at my wits end.
When pressing the brake pedal, the pedal was occasionally going nearly to
the floor, when pumped twice it would be OK and the brake pedal pressure
would be fine for days, I replaced the master cylinder with a new one from
Europarts UK and everything has been OK for a week, now the original problem
has happened again, brake pedal will go to the floor and pumped twice it
will have a good brake pedal and the brake pedal pressure
would be OK, brake pedal pressure is good and when braking car does not veer
from a straight line,
can anyone diagnose this problem as to why
brake pedal pressure keeps dropping from time to time? can't see any leaks,
master cyl reservoir fluid level is not dropping
Ps my audi 80 1.9TDI avant has got ABS discs brakes all round, 1994 model.
Thanks

The brake circuit is simple and there seems to be nothing wrong.
Keep in mind that also the clutch is getting it's fluid from the reservoir.
Maybe there is something wrong?
Just my 2 cents...

Re: strange brake problem
Yes the clutch is fed from the reservoir too, nothing wrong with the clutch
operation, could this fault be caused by a sticking brake calliper?, the
brakes are ok when the brake pedal pressure is fine, does not pull from side
to side, just a thought? I will jack up the car and check each wheel, it's
annoying you want to know that you have good brakes all the time

Your new M/C is likely junk. Especially if it was a "rebuilt" rather
than "new" piece.
