Solution

1. Preparation

Gather Tools and Parts: Ensure you have the necessary tools and replacement parts available.
Safety Precautions: Disconnect the battery to prevent electrical shorts and allow the vehicle to cool down if it has been running.

2. Brake Inspection and Replacement

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads. Replace if less than 3 mm.
- Inspect the rotors for grooves or scoring. Resurface or replace if necessary.
Replace Brake Pads:
- Remove caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang).
- Remove old pads and install new ones, ensuring proper alignment.
- Reinstall the caliper and torque the bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).

3. Wheel Bearing Inspection and Replacement

Check for Play:
- With the vehicle lifted, grasp the wheel and check for lateral movement.
Remove Hub Assembly (if necessary):
- Remove the wheel and brake caliper as described above.
- Unbolt the hub assembly from the steering knuckle and remove it.
Replace Bearing:
- Press out the old bearing and press in the new one using a bearing press.
- Reinstall the hub assembly and torque the bolts to the manufacturer's specifications.

4. Reassembly

Reinstall the wheel and lug nuts, lowering the vehicle back to the ground.
Torque lug nuts to 76-83 ft-lbs in a crisscross pattern.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Brake cleaner
Bearing press (if replacing wheel bearings)

Parts Required:

New brake pads
New brake rotors (if necessary)
New wheel bearings (if necessary)

Estimated Repair Time: 2-4 hours

Safety Warnings:

Always use jack stands when working under a vehicle.
Allow the vehicle to cool before working on brakes to avoid burns.
