What are the technical specifications of the brakes on a 2009-2016 Audi S4?
The 2009-2016 Audi S4 features ventilated disc brakes with 14.4-inch front rotors and 13-inch rear rotors. The front brakes utilize 6-piston calipers, while the rear uses 2-piston calipers. These specifications ensure optimal stopping power and heat dissipation, compatible with other B8 platform models.
Q2 What maintenance is required for the brakes on a 2009-2016 Audi S4?
What maintenance is required for the brakes on a 2009-2016 Audi S4?
Brake maintenance should include inspecting pads and rotors every 15,000 miles, replacing pads every 30-50,000 miles, and rotors every 60-80,000 miles. Regular brake fluid changes (every 30,000 miles) and cleaning brake components are also recommended. Use Audi-approved parts for compatibility.
Q3 How do I replace the brakes on my 2009-2016 Audi S4?
How do I replace the brakes on my 2009-2016 Audi S4?
Replace brakes by jacking the car, removing wheels, and taking off calipers. Remove old rotors and install new ones, then reattach calipers with new pads. Bleed the brake system to remove air and test drive to ensure proper function.
Q4 How can I troubleshoot common brake issues in my 2009-2016 Audi S4?
How can I troubleshoot common brake issues in my 2009-2016 Audi S4?
Squeaking may indicate worn pads. Vibration could mean warped rotors. A spongy pedal suggests air in lines or bad fluid. Solutions include replacing pads, resurfacing rotors, or bleeding the system.
Q5 How can I optimize the performance of my brakes?
How can I optimize the performance of my brakes?
Upgrade to high-performance pads (e.g., Pagid) and rotors, use DOT 4 fluid, and clean components regularly. For track use, consider more frequent system bleeding.
