Solution

1. Preparation

Tools Needed: Jack, jack stands, lug wrench, OBD-II scanner, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues while working on the brakes.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle.
Secure the vehicle on jack stands to ensure safety.

3. Remove Rear Wheel

Use a lug wrench to remove the lug nuts from the rear wheel.
Take off the rear wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the brake rotor; support it using a bungee cord or similar to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper for any signs of damage or sticking.
- If worn, install new brake pads, ensuring they are properly aligned and seated.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for scoring or damage.
If replacement is needed, remove the caliper bracket bolts and take off the rotor.
Install the new rotor, ensuring it is seated properly on the hub.

6. Reassemble Brake Components

Reattach the caliper over the new brake pads and tighten the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

7. Lower the Vehicle and Conduct Final Checks

Remove jack stands and carefully lower the vehicle.
Tighten the lug nuts to the specified torque (usually 75-100 ft-lbs).
Reconnect the battery.
