Solution

1. Preparation

Gather tools and parts before starting.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves for protection.

2. Remove Rear Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts on the rear wheel while on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the rear wheel.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, socket set, brake cleaner
Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor, suspending it with a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or leaks.
5. Clean the caliper and bracket with brake cleaner.
6. Insert new brake pads into the caliper bracket, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotor (if necessary)

Tools Required: Rotor puller (if rotor is stuck), torque wrench
Sub-steps:
1. If the rotor is damaged, remove it from the hub by unscrewing the retaining screws (if applicable).
2. Clean the hub surface where the rotor sits.
3. Install the new rotor onto the hub and secure it.
4. Torque the rotor retaining screws to the manufacturer's specifications (typically 80-100 in-lbs).

5. Reassemble Brake Components

Tools Required: Torque wrench
Sub-steps:
1. Reposition the caliper over the new brake pads and rotor.
2. Reinstall the caliper bolts and torque them to the manufacturer's specifications (typically 20-25 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Tools Required: Torque wrench
Sub-steps:
1. Lower the vehicle back to the ground.
2. Torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
3. Pump the brake pedal a few times to seat the brake pads.
