Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery for safety.

2. Inspect and Replace Damaged Rubber Components

Inspect Serpentine Belt:
- Remove the belt by loosening the tensioner pulley using a socket and ratchet.
- Check for cracks, fraying, or glazing on the belt surface.
- If damaged, replace with a new serpentine belt (OEM recommended).
Inspect Other Rubber Components:
- Check for worn or melted rubber hoses and grommets.
- Replace any damaged hoses with OEM parts.

3. Brake Inspection and Maintenance

Inspect Brake Components:
- Remove the wheel to access brake components.
- Look for signs of excessive wear on brake pads and rotors.
- If pads are worn down to the metal or rotors are damaged, replace them.
Brake Pad and Rotor Replacement:
- Remove old brake pads and rotors using a socket set.
- Install new rotors and brake pads ensuring correct orientation and fit.
- Torque bolts to the manufacturer's specifications (typically around 75-85 ft-lbs for caliper bolts).

4. Reassemble and Test

Reattach the wheel and lower the vehicle back to the ground.
Reconnect the battery.
Start the engine and allow it to idle while monitoring for any abnormal smells or noises.
Test drive the vehicle to ensure the issue is resolved.
