Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Gently slide the caliper off the brake rotor.
- Inspect brake pads for uneven wear; replace if necessary.
Replacement:
- If pads are worn unevenly, remove old pads and install new ones.
- Ensure the friction material is oriented correctly.

4. Inspect and Service Calipers

Check the caliper pistons for proper movement by pushing them back gently.
If calipers are sticking, consider cleaning or replacing them.
Lubricate caliper slide pins with high-temperature grease.

5. Check Brake Rotors

Measure rotor thickness with a micrometer.
If rotors are warped or below the minimum thickness, replace them.
Resurface rotors if they are within specifications and not damaged.

6. Reassemble and Test

Reinstall the caliper and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Put the wheel back on and torque lug nuts in a star pattern to manufacturer specifications.
Lower the vehicle and pump the brake pedal to ensure proper caliper engagement.
