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
