Solution

1. Preparation

Gather tools such as a socket set, torque wrench, brake cleaner, and a brake pad spreader.
Ensure the vehicle is parked on a flat surface with the parking brake applied.

2. Inspect and Clean Brake Components

Sub-steps:
1. Remove the wheel covering the affected brake.
2. Clean the brake components with brake cleaner to remove dust and debris.
3. Inspect the brake pads for uneven wear; replace if necessary.
4. Check the rotors for warping or scoring.

3. Replace Brake Pads (if necessary)

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper off the rotor and support it; do not let it hang on the brake line.
3. Remove the old brake pads and install new pads, ensuring they are properly seated.
4. Compress the caliper piston using a brake pad spreader before re-installing the caliper.
5. Reattach the caliper and torque the bolts to manufacturer's specifications.

4. Brake Caliper Inspection

Sub-steps:
1. Inspect the caliper for any signs of leakage or damage.
2. Ensure the caliper slides freely on its mounting bracket; lubricate if necessary.
3. Reassemble any components that were removed during inspection.

5. Test Drive

Sub-steps:
1. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.
2. Lower the vehicle and perform a test drive to assess the braking performance.
3. Monitor for any dragging sensations or abnormal noises.
