Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear tires for added safety.

2. Remove Wheel

Use a lug wrench to loosen the wheel lugs slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel completely.

3. Inspect Brake Components

Brake Pads and Rotors:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and secure it with a bungee cord to avoid stressing the brake line.
- Measure rotor thickness with a micrometer; replace if below specifications or if warping is visible.
- Check brake pads for even wear; replace if they are worn unevenly.
Brake Calipers:
- Ensure the caliper piston is functioning properly; push it back gently and check for resistance.
- Inspect the caliper slides and lubricate if necessary.

4. Reassemble Components

Reinstall the caliper over the rotor and tighten the caliper bolts to the manufacturer's torque specifications.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

5. Test Drive

Conduct a test drive to check for any vibrations or noises during braking.
Monitor the braking performance and address any remaining issues.
