Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen the lug nuts of the wheel where you will inspect the brake pads.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads for uneven wear.
- Sub-steps:
  - Compare the thickness of all pads.
  - Look for signs of scoring or cracking on the rotors.
Check calipers for proper operation.
- Sub-steps:
  - Ensure caliper slides are clean and lubricated.
  - Check for any signs of rust or corrosion on the caliper housing.

4. Replace or Adjust Components

If brake pads are worn unevenly, replace them with new brake pads.
- Sub-steps:
  - Remove the caliper by unscrewing the mounting bolts.
  - Slide off the old brake pads.
  - Clean the caliper bracket and install new brake pads.
  - Reinstall the caliper and torque bolts to manufacturer specifications (usually around 20-30 ft-lbs).
If caliper issues are found, consider replacing the caliper.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the recommended torque (typically 80-100 ft-lbs).
Test drive the vehicle to ensure proper brake function.
