Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake cleaner
C-clamp or brake caliper tool
Socket set

2. Remove Wheel

Loosen the lug nuts on the wheel where the uneven brake pad wear is observed.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket using the appropriate socket.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper pins and bushings for wear; replace if necessary.
Use a C-clamp to compress the caliper piston back into the caliper housing to make space for the new pads.
Install the new brake pads, ensuring they are seated correctly in the caliper bracket.
Reattach the caliper and torque the bolts to the manufacturer’s specifications.

4. Inspect and Replace Rotors (if necessary)

Check the rotors for signs of warping or excessive wear.
If the rotors are below the minimum thickness specification, remove them by unbolting the rotor from the hub.
Replace with new rotors, ensuring they are clean and free of debris.
Torque the rotor bolts to the specified values.

5. Reassemble and Repeat for Other Wheels

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer’s specifications.
