Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Wear safety goggles and gloves for protection.
- Loosen the lug nuts on the rear wheels slightly without removing them.

2. Lift the Vehicle

Sub-steps:
- Use a jack to lift the rear of the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the rear wheels to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Check the brake pads for wear. If the pads are worn below the minimum thickness (usually 3mm), replace them.
- Remove the old brake pads and install new ones, ensuring they are properly seated.
- Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).

4. Inspect and Resurface or Replace Rotors

Sub-steps:
- Check the rotor surface for grooves or discoloration. If damaged, consider resurfacing or replacing the rotors.
- If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install a new rotor and torque the retaining screws to specification.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheels and hand-tighten the lug nuts.
- Lower the vehicle from the jack stands.
- Torque the lug nuts to the recommended specification (usually 75-80 ft-lbs).
- Test the brake pedal and ensure it feels firm before driving.
