Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent vehicle movement.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.

2. Remove Wheel

Loosen the lug nuts on the wheel with the brake issue while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Check the brake pads for wear; replace if less than 3mm thickness remains.
If they are worn, remove the caliper by unscrewing the caliper bolts and sliding it off the rotor.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket with brake cleaner and ensure the surface is free of debris.
Install new brake pads in the caliper bracket, ensuring they are properly aligned.

4. Inspect and Resurface/Replace Rotors

Check rotors for scoring or uneven wear. If grooves are present, consider resurfacing or replacing them.
If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new or resurfaced rotors, ensuring they are clean and free of oil or grease.

5. Reassemble Braking System

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque (typically around 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle back to the ground and tighten the lug nuts to the manufacturer's specified torque (typically around 76 lb-ft).
Pump the brakes several times to seat the pads against the rotor.
Perform a test drive to ensure the noise is resolved and the braking system is functioning properly.
