Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety goggles and gloves.

2. Brake Inspection and Replacement

Lift the Vehicle
- Use a jack to raise the vehicle and secure it with jack stands.
- Remove the wheel using a socket set.
Inspect Brake Components
- Check brake pads for thickness; if less than 3mm, replace them.
- Inspect rotors for grooving or scoring; if damaged, replace the rotors.
Replace Brake Pads and Rotors
- Remove the caliper bolts and gently slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- If replacing rotors, remove the retaining screws and take off the rotor.
- Install new rotors (if applicable) and torque screws to manufacturer specifications.
- Insert new brake pads into the caliper bracket and apply brake grease on contact points.
- Reattach the caliper, ensuring bolts are torqued to specification.

3. Wheel Bearing Inspection and Replacement

Check Wheel Bearings
- Spin the wheel by hand and listen for roughness or grinding.
- If noise is present, proceed to replace the wheel bearing.
Remove Wheel Hub
- Remove the brake caliper and rotor as previously described.
- Disconnect the axle nut using a socket set.
- Remove the wheel hub assembly by unbolting the hub from the steering knuckle.
Install New Wheel Bearing
- Press or install the new wheel bearing into the hub assembly.
- Reassemble the hub onto the steering knuckle and secure with bolts.

4. Reassembly and Lowering Vehicle

Reattach All Components
