Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety: Engage the parking brake and wear appropriate personal protective equipment (PPE).

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Use a socket set to remove the caliper bolts.
3. Carefully lift the caliper off the rotor and support it without hanging by the brake line.
4. Remove the old brake pads from the caliper bracket.
5. Inspect the caliper for any signs of damage or corrosion.
6. Insert new brake pads, ensuring they are seated properly in the caliper bracket.
7. Reinstall the caliper and torque the bolts to manufacturer specifications (usually around 25-30 Nm).
8. Reinstall the wheel and torque the lug nuts to the specified value (usually 100-120 Nm).

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are scored or warped, remove them by unscrewing the rotor screws (if equipped) and pulling them off the hub.
2. Clean the hub surface to ensure a smooth fit for the new rotor.
3. Install new rotors, ensuring they are correctly oriented and seated.
4. Reinstall any retaining screws and torque them to the specified value.

4. Check Drive Belts

Sub-steps:
1. Inspect the serpentine belt for cracks, fraying, or glazing.
2. Use a belt tension gauge to check the tension; adjust if necessary.
3. Replace the belt if any signs of wear are present.

5. Inspect Wheel Bearings

Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Spin the wheel by hand and listen for noise; check for excessive play by wiggling the wheel.
3. If the bearings are noisy or loose, they will need to be replaced.
