Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and use wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a lug wrench.
2. Lift the vehicle with a jack and secure it on jack stands.
3. Remove lug nuts completely and take off the wheel.

3. Inspect Brake Components

Sub-steps:
1. Check brake pads for uneven wear; replace if necessary.
2. Inspect rotors for any warping or damage; machine or replace as needed.
3. Examine caliper slides and ensure they move freely; clean and lubricate if sticking.

4. Replace Brake Pads (if needed)

Sub-steps:
1. Remove the caliper by unscrewing the mounting bolts and lifting it off the rotor.
2. Remove old brake pads from the caliper bracket.
3. Compress the caliper piston using a brake caliper tool to make space for new pads.
4. Install new brake pads into the caliper bracket.
5. Reattach the caliper and secure it with the mounting bolts to the specified torque (typically 20-30 ft-lbs, verify with service manual).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 76-80 ft-lbs).
3. Reconnect the battery and test brake operation without driving.
