Just wondering what everyone thinks about this issue. During some spirited driving the other week in my RS3 (61 reg 6000 miles). I was caught up behind a tractor and noticed my brakes felt " Spongy - not right ", I continued on with care @ 15 mph for another mile or so @ good distance from the tractor, it braked and turned off, at this point,I realised my brake pedal had lost all pressure, i just pushed the pedal to the floor, only the sound of slight grinding & no stopping. Thankfully I used the traditional handbrake and slowed the car without any problems or heart attacks. I limped the car home 50 odd miles using the handbrake and dropped the car into Audi the next morning, that was 10 days ago. The mechanic's have said they have found nothing wrong in diagnostics and test drives,They agreed the brakes where slightly spongy, so bleed the brakes as a precaution. They have invited me in to test drive the car tomorrow, but am slightly concerned that, had the pedal failed 5 minutes earlier, I wouldn't be writing this. If the brakes where goosed then I could understand, but how can they completely malfunction, no waring lights or senors & then miraculously be ok again ? FYI the car has been an absolute beauty, in every other aspect of the 6000 miles, I have refrained from posting just incase i jinx my own car, but.... here i am.
