Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the rear of the vehicle using a jack and secure it with jack stands.

2. Remove Rear Wheel

Using a lug wrench, loosen the lug nuts on the rear wheel.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully lift the caliper off the rotor and support it using a bungee cord.
- Remove the old brake pads from the caliper bracket.
- Check the caliper piston; compress it if necessary using a brake caliper tool.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.
Tools Required: Socket set, brake caliper tool.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Remove the caliper bracket by unscrewing the bolts.
- Slide the rotor off the hub; inspect for any signs of warping or scoring.
- If the rotor is damaged, replace it with a new one.
- Clean the hub surface and install the new rotor, ensuring it sits flush.
Tools Required: Socket set, brake cleaner.

5. Reassemble and Lubricate

Sub-steps:
- Reattach the caliper bracket and torque the bolts to the manufacturer’s specifications.
- Apply brake grease to the backing plate of the brake pads and any contact areas.
- Reinstall the caliper over the new brake pads and secure it with bolts.
Torque Values: Refer to manufacturer specifications for caliper bracket bolts.

6. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.
Torque Values: Typically 80-100 ft-lbs; confirm with manufacturer specifications.
