Two problems related to brake disc pads have been reported for the 2002 Audi S4. The most recently reported issues are listed below.
I purchased my audo S4 avant new on Nov. 10, 2001. It has 26,000 miles on it. There have been at least 6 repairs performed to correct brake pulsation or vibration. Pads and/or front and/or rear rotors have been replaced. The car leaves the dealership service facility operating normally, but within a few thousand miles the condition returns. Is there a real fix for this?.
Consumer stated while driving at 30 mph and when depressing brakes they vibrated/ pulsated. Vehicle was serviced, and dealer replaced front brake rotors and pads.
