Repair Instructions

Replace Brake Pads and Rotors (if necessary):
- Remove Caliper: Unbolt the caliper and suspend it with a wire to avoid stress on the brake hose.
- Remove Old Pads: Slide the old pads out of the caliper bracket.
- Replace Rotors: If replacing, remove the caliper bracket and rotor (may require a mallet if seized).
- Install New Rotors: Clean new rotors with brake cleaner to remove protective coating before installation.
- Install New Pads: Apply brake grease to the back of new pads and install them into the caliper bracket.
Reinstall Caliper:
- Compress the caliper piston using a brake caliper tool or C-clamp.
- Reinstall the caliper over the new pads and secure with bolts.
Check and Reinstall Wheel:
- Ensure all components are correctly installed and torqued to specifications.
- Reinstall the wheel and torque the lug nuts to the manufacturer’s specification.
Test Drive:
- Perform a test drive to ensure the noise is resolved.
- Listen for any abnormal noises and check for proper braking performance.
Bed-in New Brakes:
- Follow the bed-in procedure recommended by the brake pad manufacturer to ensure optimal performance and longevity.

Additional Tips

Always replace brake pads in pairs (front or rear) to ensure balanced braking.
Consider replacing hardware components such as clips and shims with new parts during brake service.
Regularly inspect brakes as part of routine maintenance to prevent noise and ensure safety.

By following these detailed steps, you should resolve the brake noise issue in your Audi Q5 effectively. If the noise persists after these repairs, further inspection by a professional may be necessary to rule out other potential issues such as wheel bearings or suspension components.
