Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel to access the brake components.

3. Inspect Brake Pads and Calipers

Remove the brake caliper bolts using a socket set.
Carefully slide the caliper off the rotor, supporting it with a bungee cord to avoid strain on the brake line.
Inspect the brake pads for uneven wear; replace if necessary.
Check that the caliper piston moves freely and is not stuck.

4. Replace Brake Pads (if uneven wear is found)

Remove old brake pads and clean the caliper bracket and rotor surface with brake cleaner.
Install new brake pads, ensuring they are aligned correctly.
Reinstall the caliper and torque the bolts to manufacturer's specifications (typically 20-25 ft-lbs).

5. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the jack.
Torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
