Solution

1. Preparation

Tools Required: Wheel chocks, jack and jack stands, socket set, brake cleaner, torque wrench.
Lift the rear of the vehicle using a jack and secure it on jack stands.
Remove the rear wheels to access the brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the brake pads and suspend it using a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads ensuring they are aligned properly in the caliper bracket.
5. Apply brake grease to the back of the pads to prevent noise.

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Remove the caliper bracket bolts and take off the bracket.
2. Inspect the rotor surface for scoring; if damaged, replace the rotor.
3. If the rotor is suitable for resurfacing, use a brake lathe to smooth the surface.
4. Clean the rotor surface with brake cleaner to remove any dust or debris.
5. Reinstall the rotor and torque it to the manufacturer's specifications.

4. Reassemble Brake Components

Sub-steps:
1. Reattach the caliper bracket over the new rotor and torque to specifications.
2. Slide the caliper back over the new pads and secure with caliper bolts.
3. Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Test Brakes

Sub-steps:
1. Lower the vehicle off the jack stands.
2. Tighten the lug nuts to the specified torque.
3. Pump the brake pedal several times to seat the brake pads properly.
4. Test drive the vehicle to ensure the noise has been resolved.
