What type of brake system does the 2012-2018 Audi S7 use?
The 2012-2018 Audi S7 is equipped with a high-performance hydraulic brake system, featuring ventilated disc brakes on both the front and rear axles. The front brakes are 365mm in diameter with 6-piston fixed calipers, while the rear brakes are 330mm in diameter with single-piston floating calipers. The system includes ABS, EBD, and ESC for enhanced safety and performance.
Q2 What is the recommended brake pad replacement interval for the Audi S7?
What is the recommended brake pad replacement interval for the Audi S7?
The recommended brake pad replacement interval for the Audi S7 is typically between 30,000 to 70,000 miles, depending on driving conditions and habits. Aggressive driving, frequent braking, or driving in hilly areas may reduce this interval. Always inspect brake pads during routine maintenance and replace them if the thickness is less than 3mm.
Q3 Can I use aftermarket brake pads on my Audi S7?
Can I use aftermarket brake pads on my Audi S7?
While aftermarket brake pads can be used, it is highly recommended to use genuine Audi brake pads or OEM-equivalent parts. Genuine parts are specifically designed for the vehicle's braking system, ensuring optimal performance, safety, and compatibility. Using non-genuine parts may affect braking efficiency and could void the vehicle's warranty.
Q4 How do I check the brake fluid level in my Audi S7?
How do I check the brake fluid level in my Audi S7?
To check the brake fluid level, locate the brake fluid reservoir under the hood. The reservoir has minimum and maximum level markings. Ensure the fluid level is between these marks. Use only DOT 4 brake fluid, as specified in the owner's manual. If the level is low, top it up and inspect the system for leaks. Brake fluid should be replaced every 2 years or 30,000 miles, whichever comes first.
Q5 What is the procedure for bleeding the brake system on an Audi S7?
What is the procedure for bleeding the brake system on an Audi S7?
Bleeding the brake system on an Audi S7 requires a two-person procedure or a pressure bleeder. Start with the wheel farthest from the master cylinder (rear right) and work towards the closest (front left). Open the bleeder valve, pump the brake pedal, and close the valve before releasing the pedal. Repeat until no air bubbles are visible in the fluid. Use only DOT 4 brake fluid and ensure the reservoir does not run dry during the process.
