Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear appropriate safety gear (gloves, safety glasses).

2. Inspect and Replace Brake Components

Remove Wheel
- Use a jack and jack stands to lift the vehicle securely.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Brake Components
- Check the brake pads for thickness; replace if below specifications (generally below 3mm).
- Inspect the brake rotor for scoring or warping; replace if necessary.
- Clean the caliper and inspect the pistons for proper movement.
Replace Parts
- If brake pads are worn, remove the caliper bolts and slide the caliper off.
- Replace the brake pads and reassemble the caliper.
- If the rotor is damaged, remove the rotor, install the new one, and secure it with the appropriate torque specifications (typically 80-100 Nm for rotor bolts).

3. Inspect Wheel Bearings

Check Wheel Bearing
- With the wheel removed, grasp the hub and try to move it side to side.
- If there is play, the wheel bearing may need replacement.
Replace Wheel Bearing (if necessary)
- Remove the axle nut and any components securing the bearing.
- Use a bearing puller to remove the old bearing.
- Install the new bearing and reassemble, ensuring all components are torqued to specification.
