Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely jack up the rear of the vehicle.
Remove the rear wheels to access the brake assembly.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Check the condition of the brake rotor; if it is scored or damaged, consider resurfacing or replacing it.
- Install new brake pads, ensuring they are correctly oriented and seated in the caliper bracket.

3. Reinstall Caliper

Sub-steps:
- Slide the caliper back over the new brake pads.
- Tighten the caliper bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs).

4. Brake Hardware Inspection

Sub-steps:
- Inspect shims and clips for damage; replace if necessary.
- Apply brake grease to the backing of the pads and contact points to reduce noise.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and tighten lug nuts to the manufacturer’s specifications.
- Lower the vehicle and pump the brake pedal a few times to seat the brake pads.
- Test drive the vehicle to check for noise and proper brake function.
