Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Remove Brake Components

Inspect Brake Pads:
- Check pads for uneven wear; replace if thickness is below 3mm.
Remove Brake Caliper:
- Unscrew the caliper bolts using a socket wrench.
- Carefully lift the caliper off the rotor, support it with a wire hanger to avoid strain on the brake line.
Remove Brake Pads:
- Slide the pads out of the caliper bracket.

4. Inspect and Replace Brake Rotor (if necessary)

Check Rotor Condition:
- Inspect for grooves or warping; replace if damaged.
Remove Rotor:
- Unscrew any retaining screws (if equipped) and slide the rotor off the hub.
Install New Rotor:
- Place the new rotor onto the hub, ensuring it is seated properly.

5. Install New Brake Pads

Apply brake grease to the back of the new pads to prevent noise.
Slide the new pads into the caliper bracket.

6. Reinstall Brake Caliper

Position the caliper over the new pads and secure it with the bolts.
Torque the caliper bolts to the manufacturer’s specifications (typically around 20-30 ft-lbs).

7. Reassemble Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specification (typically around 80-100 ft-lbs).
