2
Check the brake rotors for scoring, warping, or uneven wear.

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts before lifting the vehicle.
Remove the lug nuts completely and take off the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Inspect Pads: Check the brake pads for wear indicators; if they are less than 3mm thick, they need replacement.
Remove Caliper: Use a socket to unbolt the caliper from the bracket; support it with a bungee cord to avoid strain on the brake line.
Replace Pads: Slide out the old pads and replace them with new ones. Ensure they are seated properly in the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Check Rotors: Measure rotor thickness using a micrometer; if below manufacturer specifications or if they are scored, they should be resurfaced or replaced.
Remove Rotors: Unbolt the rotor from the hub; if stuck, gently tap with a rubber mallet.
Resurface/Replace: If resurfacing, ensure the rotor is within specifications. If replacing, install the new rotor, ensuring it is clean and free from grease.

5. Reassemble and Test

Reattach the caliper over the new pads and torque the bolts to the manufacturer's specifications (usually around 20 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a star pattern to the specified torque (typically 80-100 ft-lbs).
Test drive the vehicle to ensure the noise is resolved and brakes are functioning properly.
