What are the maintenance requirements for the brake system?
Regular maintenance includes inspecting brake pads every 10,000 miles, replacing them when worn below 1.5mm, and checking rotors for warping or excessive wear. Brake fluid should be replaced every 2 years or 24,000 miles. Ensure proper cleaning of brake components and lubrication of moving parts. Always use Audi-approved materials to maintain system integrity and performance.
Q3 How do I install or replace brake components on the Audi A6?
How do I install or replace brake components on the Audi A6?
To replace brake pads, jack up the vehicle, remove the wheels, and caliper. Slide out the old pads, insert the new ones, and reinstall the caliper. For rotors, remove the caliper and rotor, install the new rotor, and reinstall the caliper. Bleed the brake system if air enters the lines. Always follow proper safety procedures and consult a professional if unsure.
Q4 How do I troubleshoot common brake issues?
How do I troubleshoot common brake issues?
If the brake warning light illuminates, check the brake fluid level and connections. For spongy brakes, bleed the system to remove air. Grinding noises may indicate worn pads or warped rotors. Vibrations during braking could signal uneven rotor wear. Consult a professional for comprehensive diagnostics and repairs.
