Solution

1. Preparation

Gather Tools: Gather necessary tools including a jack, jack stands, lug wrench, caliper tool, torque wrench, and a brake cleaner.
Safety First: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses and gloves.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use the 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 Caliper:
- Locate the caliper mounting bolts and remove them using a socket.
- Carefully lift the caliper off the rotor without disconnecting the brake line. Support it with a bungee cord or similar to avoid stress on the brake line.
Check Brake Pads:
- Inspect the pads for uneven wear. If one side is significantly thinner, it may need replacement.
- Measure the remaining thickness to determine if they are within acceptable limits.
Replace Brake Pads:
- If uneven wear is confirmed, remove the old brake pads from the caliper bracket.
- Apply brake grease to the backing of the new pads to prevent noise and aid installation.
- Install the new pads into the caliper bracket ensuring proper positioning.

4. Reassemble Braking System

Reinstall Caliper:
- Compress the caliper piston using a caliper tool to accommodate the new pads.
- Carefully slide the caliper back over the new pads and secure it with mounting bolts.
- Torque the caliper bolts to the manufacturer’s specifications (consult the service manual).
Reinstall Wheel:
- Place the wheel back on the hub and hand-tighten the lug nuts.
- Lower the vehicle from the jack stands and torque the lug nuts to the recommended specifications.

5. Final Checks

Pump the brake pedal a few times to ensure the caliper pistons are seated properly.
Check the brake fluid level and top off as necessary.
