Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using a socket set.

3. Remove Brake Components

3.1 Remove the brake caliper:
- Use a socket to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it using a hook or bungee cord.
3.2 Remove the brake pads:
- Slide the pads out of the caliper bracket.
3.3 Remove the rotor (if necessary):
- If the rotor is stuck, tap it gently with a hammer to loosen it.

4. Inspect and Replace Parts

4.1 Inspect brake pads:
- Replace if the material is below the minimum thickness (usually 3mm).
4.2 Inspect brake rotors:
- Replace if they are worn beyond service limits or have deep grooves.
4.3 Replace hardware:
- Replace any damaged or worn shims, clips, or caliper bushings.

5. Reassemble Components

5.1 Install new brake pads:
- Slide the new pads into the caliper bracket.
5.2 Reinstall the brake caliper:
- Position the caliper over the new pads and secure it with the mounting bolts. Torque to manufacturer specifications (typically around 30 Nm).
5.3 Reinstall the rotor (if removed):
- Place the rotor back onto the hub.

6. Final Checks

Reinstall the wheels and lower the vehicle.
Tighten the lug nuts to the specified torque (usually around 100 Nm).
Pump the brake pedal a few times to ensure proper pad seating.
