Repair Instructions

Repair or Replace Faulty Components:
- Brake Lines: If a line is cracked or corroded, replace it. Use a brake line wrench to avoid rounding the fittings.
- Hoses: Replace any hoses that show signs of cracking or leakage.
- Calipers/Wheel Cylinders: Rebuild or replace if leaking. Ensure all seals are in good condition.
Reassembly:
- Reassemble any components that were removed during inspection.
- Ensure all connections are tight and secure.
Bleeding the Brake System:
- After repairs, bleed the brake system to remove any air. Start with the wheel farthest from the master cylinder, typically the right rear.
- Use the following bleeding sequence: right rear, left rear, right front, left front.
- Have an assistant press the brake pedal while you open the bleed screw, allowing fluid and air to escape. Close the screw before the pedal is released.
Refill and Test:
- Refill the brake fluid reservoir with DOT 4 brake fluid.
- Check for leaks by pressing the brake pedal several times, ensuring it feels firm.
- Test drive the vehicle at low speed to ensure braking performance is restored.
Final Checks:
- Re-inspect all areas for any sign of new leaks.
- Ensure the brake fluid level remains constant after the test drive.

Safety Precautions

Always wear safety glasses and gloves when working with brake fluid.
Dispose of used brake fluid responsibly; it is hazardous to the environment.

By following these steps, you can effectively diagnose and repair a brake fluid leak in an Audi Q5 8R, ensuring the vehicle’s braking system is safe and functional.
