Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, caliper tool.
Safely lift the vehicle and remove the rear wheels.
Ensure the vehicle is on a flat, stable surface and secure it with wheel chocks.

2. Remove Brake Components

Remove Caliper Bolts:
- Use a socket wrench to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
Remove Brake Pads:
- Slide the brake pads out of the caliper bracket.
- Inspect them for uneven wear or damage.

3. Inspect and Clean

Inspect Rotors:
- Check the rotors for signs of scoring or warping.
- Measure rotor thickness to ensure it meets the manufacturer's specifications.
Clean Components:
- Use brake cleaner to remove dust and debris from the brake pads, calipers, and rotors.
- Wipe down all components to ensure a clean surface.

4. Reassemble and Adjust

Reinstall Brake Pads:
- If the pads are in good condition, reinstall them into the caliper bracket.
- If worn, replace them with new pads.
Reinstall Caliper:
- Position the caliper over the new or cleaned pads.
- Tighten the caliper bolts to the manufacturer’s specified torque.

5. Final Checks

Reinstall the wheels and lower the vehicle.
Torque the lug nuts to the manufacturer’s specification.
Pump the brake pedal a few times to seat the pads against the rotors.
