Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to eliminate any electrical hazards.

2. Remove Rear Wheel

Use a jack to lift the rear of the vehicle and place jack stands for safety.
Remove the lug nuts using a socket set and take off the rear wheel.

3. Inspect and Replace Brake Pads

Check the condition of the brake pads:
- If worn below specifications (typically 3mm), replace them.
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.

4. Resurface or Replace Rotors

Inspect the brake rotors for damage; if they are scored, consider resurfacing or replacing them:
- If resurfacing, follow manufacturer specifications for thickness.
- If replacing, remove the caliper bracket bolts and slide off the rotor.
- Install the new or resurfaced rotor, ensuring it is properly seated.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor, ensuring to torque the caliper bolts to the manufacturer’s specifications.
Reinstall the rear wheel and torque the lug nuts in a crisscross pattern.

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper brake pad seating.
Test the brake system for functionality.
