Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before beginning any work.

2. Inspect and Replace Brake Components

Remove Wheel
- Use a lug wrench to loosen lug nuts.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the wheel completely.
Inspect Brake Pads and Rotors
- Check brake pads for wear; replace if thickness is below 3mm.
- Inspect rotors for scoring or warping; replace if necessary.
- Tools required: Socket set, torque wrench.
Replace Brake Pads/Rotors if Needed
- If replacement is necessary, remove the caliper by unbolting it.
- Slide the old pads out and replace with new pads.
- Reattach caliper and torque bolts to manufacturer specifications (typically around 25-30 Nm).
- If rotor replacement is needed, remove the rotor and install the new one, making sure to clean the hub surface.

3. Inspect and Replace Wheel Bearings (if applicable)

Remove Hub Assembly
- Remove the brake caliper and rotor as previously described.
- Unbolt and remove the hub assembly from the steering knuckle.
Replace Wheel Bearings
- Use a bearing puller to remove the old bearing.
- Press in the new bearing using a hydraulic press or suitable tool.
- Reassemble the hub assembly and ensure proper torque settings.

4. Inspect and Repair Drivetrain Components

Check Driveshaft and CV Joints
- Inspect the driveshaft for any signs of damage or wear.
- Check CV joints for any tears or leaks in the boot.
- Replace any damaged components as needed.
