2006 Audi A4 Quattro Q&A
2006 Audi A4 Quattro Question: My brakes are at 50% - what does this mean?
Barbara, Brake pads should be replaced when they are at 15-20% remaining. Depending on where you live, what you drive and how you drive determines how long it will take to get to that point, so it's important to have them checked regularly. - lawrenceg
50% left on your brakes means that after driving 35,000 miles you used 50% of you brake pad lining so you should be able to go about 25,000 miles on whats left of your brake pads, You don't want to go too far with whats left because you take a chance of the pad backing hitting the Brake Rotor and that could be very expensive. - hemicuda
audi brake pads should be replaced when their is <4mm pad material remaining. there is a tool to measure the wear without pulling the wheels. incidentally 4mm is the maximum thickness at which audi warranty will cover brake pad replacement - spyder
