Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if working on electrical components).

2. Wheel Removal

Loosen the lug nuts on the wheel with uneven brake wear.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Brake Pad Inspection and Replacement

Inspect the brake pads for uneven wear and measure their thickness.
If replacing, remove the caliper bolts using a socket set.
Carefully lift the caliper off the brake rotor and support it to avoid stressing the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads, ensuring they are seated properly.

4. Caliper and Rotor Check

Inspect the brake rotor for wear or warping; replace if necessary.
If the caliper is sticking, check the caliper slides for lubrication and movement.
Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.

5. Wheel Reinstallation

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specification.

6. Final Checks

Reconnect the battery if it was disconnected.
Pump the brake pedal to ensure proper brake pad contact before driving.
