Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as required.
Secure the vehicle on jack stands to ensure stability.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store the lug nuts in a safe place.

4. Inspect and Replace Brake Pads

Inspect:
- Examine the brake pads and calipers for uneven wear.
- Check the brake rotor surface for any signs of damage or warping.
Replace:
- If uneven wear is due to worn pads, remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.
- Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 25-35 ft-lbs).

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).

6. Test Brakes

Pump the brake pedal several times to seat the pads before road testing.
Conduct a test drive to ensure proper braking function and check for any abnormal noises.
