Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper gauge, brake cleaner, clean rags.
Park the vehicle on a flat surface and engage the parking brake.
Gather all necessary tools and safety equipment (gloves, safety glasses).

2. Lift the Vehicle

Use a lug wrench to loosen the lug nuts on the front or rear wheels.
Lift the vehicle using a jack and support it securely with jack stands.
Remove the wheels to access the brake assembly.

3. Inspect the Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and suspend it using a wire or bungee cord (do not let it dangle on the brake line).
- Remove the brake pads from the caliper bracket.
- Inspect each pad for uneven wear; look for significant differences in thickness between inner and outer pads.

4. Replace Worn Brake Pads

Sub-steps:
- If uneven wear is detected, replace the brake pads with new ones. Ensure to use OEM or high-quality aftermarket pads.
- Apply brake grease to the backing of the new pads to reduce noise and ensure smooth operation.
- Reinstall the brake pads into the caliper bracket.

5. Reassemble and Test

Sub-steps:
- Reposition the caliper over the new brake pads and secure it with the caliper bolts. Torque to manufacturer specifications (typically around 25-35 ft-lbs).
- Reinstall the wheels and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specification (typically around 76-83 ft-lbs).

6. Final Checks

Press the brake pedal a few times to seat the pads against the rotor.
Test drive the vehicle to ensure proper braking performance and listen for any unusual noises.
