Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Lift Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the front or rear wheels, depending on where the uneven wear is observed.

3. Inspect Brake Components

Caliper Check:
- Remove the caliper by unscrewing the mounting bolts.
- Inspect the caliper slides and ensure they are lubricated and not seized.
- If the caliper is malfunctioning, replace it with a new one.
Brake Pad Inspection:
- Remove the brake pads and measure their thickness.
- Replace any pads that are below the manufacturer’s recommended thickness.
Rotor Inspection:
- Check brake rotors for thickness and warping using a micrometer.
- Resurface or replace the rotors if they are out of spec.

4. Reassembly

Reinstall the brake pads ensuring they are properly seated.
Reattach the caliper and torque the bolts to the manufacturer’s specifications (typically around 30-50 ft-lbs).
Reinstall the wheels and lower the vehicle.

5. Brake System Bleeding (if applicable)

If any brake fluid was lost, bleed the brake lines to remove air bubbles.
Use a brake bleeder kit and have an assistant pump the brake pedal.

6. Final Checks

Reconnect the battery and test the brake pedal feel before driving.
Check for any unusual noises during initial braking.
