Solution

1. Preparation

Tools Required: Jack stands, lug wrench, socket set, torque wrench, C-clamp, brake cleaner, wire brush, and safety glasses.
Sub-steps:
1. Park the vehicle on a flat surface and engage the parking brake.
2. Loosen the lug nuts on the rear wheels slightly while the vehicle is on the ground.
3. Use a jack to lift the rear of the vehicle and secure it with jack stands.
4. Remove the rear wheels to access the brake components.

2. Inspect and Clean

Sub-steps:
1. Remove the brake caliper bolts with a socket set and carefully slide the caliper off the rotor.
2. Hang the caliper using a bungee cord or similar to avoid stressing the brake line.
3. Take out the brake pads from the caliper bracket.
4. Clean the caliper bracket and the rotor surface with brake cleaner.
5. Use a wire brush to clean any rust or debris from the caliper bracket.

3. Replace Brake Pads (if necessary)

Sub-steps:
1. Check the condition of the brake pads; if they are worn beyond the manufacturer's specifications, replace them.
2. Install new brake pads in the caliper bracket, ensuring they are correctly oriented.
3. Use a C-clamp to compress the caliper piston back into the caliper housing to accommodate the new pads.

4. Reassemble

Sub-steps:
1. Reposition the caliper over the new brake pads and align it with the bracket.
2. Tighten the caliper bolts to the manufacturer’s torque specifications (typically around 25-30 ft-lbs).
3. Reinstall the rear wheels and hand-tighten the lug nuts.

5. Final Checks

Sub-steps:
1. Lower the vehicle back to the ground and completely tighten the lug nuts in a star pattern to the manufacturer’s specifications (typically around 76 ft-lbs).
2. Pump the brake pedal several times to ensure proper engagement of the brake pads and caliper.
3. Test drive the vehicle to confirm that the squeaking noise has ceased.
