Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Wheel Removal

Tools Required: Socket set, jack, jack stands
Loosen the lug nuts on the wheel with the uneven brake wear.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Pad and Rotor Inspection

Inspect the brake pads for uneven wear.
Check the brake rotors for signs of warping or scoring.
If the rotor is damaged, it should be resurfaced or replaced.

4. Caliper and Hardware Inspection

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it without stressing the brake line.
Inspect caliper slides and pins for rust or debris; clean and lubricate if needed.

5. Replace Brake Pads

If wear is uneven, replace all brake pads on that axle.
Tools Required: Torque wrench
Remove the old brake pads and install new ones, ensuring they fit correctly.
Torque caliper bolts to manufacturer's specifications.

6. Reassemble and Test

Reattach the caliper over the new pads.
Replace the wheel and hand-tighten the lug nuts.
