Always measure rotor thickness during service to ensure it meets the minimum specified thickness of 28 mm (front) and 18 mm (rear).
Q2 What type of brake fluid is recommended for the Audi S6?
What type of brake fluid is recommended for the Audi S6?
The 1994-1997 Audi S6 requires DOT 4 brake fluid with a minimum dry boiling point of 230°C (446°F) and a wet boiling point of 155°C (311°F). Audi recommends using genuine or equivalent high-performance brake fluid to ensure optimal braking performance and system longevity.
Q3 How often should the brake pads be replaced on the Audi S6?
How often should the brake pads be replaced on the Audi S6?
Brake pad replacement intervals vary based on driving conditions, but Audi recommends inspecting the brake pads every 10,000 miles. The minimum pad thickness is 3 mm, including the backing plate. Aggressive driving or track use may require more frequent inspections and replacements.
Q4 What is the proper procedure for bleeding the brake system on the Audi S6?
What is the proper procedure for bleeding the brake system on the Audi S6?
The brake system should be bled using a pressure bleeder to ensure air is completely removed. Start with the wheel farthest from the master cylinder (rear right), followed by rear left, front right, and front left. Use only DOT 4 brake fluid and ensure the reservoir does not run dry during the process.
Q5 Can I upgrade the brake system on my 1994-1997 Audi S6?
Can I upgrade the brake system on my 1994-1997 Audi S6?
Yes, the brake system can be upgraded with larger rotors, high-performance calipers, and upgraded pads.
