Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle and secure it on jack stands.
Remove the rear wheels using a lug wrench.

3. Remove Brake Components

Brake Caliper Removal:
- Locate the caliper mounting bolts on the back of the caliper.
- Use a socket set to remove the bolts and slide the caliper off the rotor.
- Support the caliper with a bungee cord or rope to avoid straining the brake line.
Brake Pad Removal:
- Remove the retaining clips or pins holding the brake pads in place.
- Slide out the old brake pads from the caliper bracket.
Rotor Removal (if necessary):
- Check for any screws or retaining clips holding the rotor in place and remove them.
- Slide the rotor off the hub.

4. Inspect and Replace Components

Brake Pad Replacement:
- Compare new brake pads with old pads to ensure correct size.
- Apply brake grease to the back of the new pads (avoid contact with the friction material).
- Install new brake pads into the caliper bracket.
Rotor Replacement:
- Inspect the new or resurfaced rotor for any protective oil; clean it with brake cleaner if necessary.
- Install the new rotor onto the hub, securing it if needed.

5. Reassemble Braking System

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (typically around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle off the jack stands using the jack.
Torque the lug nuts to the specified manufacturer’s value (usually around 76 ft-lbs).
