Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Use wheel chocks for extra safety.

2. Inspect and Replace Brake Components

Lift the Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheels for access to the brake components.
Inspect Brake Pads:
- Examine the brake pads for thickness; replace if below 3mm.
- Check for uneven wear or cracking.
Inspect Brake Rotors:
- Check the rotors for scoring or warping; replace if necessary.
- Clean the rotor surface with brake cleaner if still usable.
Replace Brake Pads and Rotors (if needed):
- Remove the caliper bolts and lift the caliper off the rotor.
- Replace the pads and reinstall the caliper.
- If rotors are replaced, remove the old rotors and install new ones, ensuring they are torqued to specifications.

3. Check and Replace Serpentine Belt (if applicable)

Inspect the Serpentine Belt:
- Look for cracks, fraying, or glazing.
- If damaged, remove the belt by releasing tension from the tensioner pulley.
Install New Serpentine Belt:
- Route the new belt according to the diagram on the vehicle.
- Reapply tension and ensure proper alignment.

4. Inspect and Replace Wheel Bearings (if applicable)

Check Wheel Bearings:
- Spin the wheel and listen for any grinding noises.
- If needed, remove the wheel and hub assembly.
Replace Wheel Bearings:
- Remove the old bearings and install new ones, ensuring they are properly greased and seated.
- Reassemble the hub and wheel assembly.
