Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cooled down.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect and Replace Worn Belts

Tools Required: Socket set, belt tension gauge
Inspect the serpentine belt for cracks or fraying.
If damaged, loosen the tensioner using a socket and remove the belt.
Install a new serpentine belt, ensuring it is properly routed and tensioned according to the manufacturer's specifications.

3. Brake Component Check

Tools Required: Jack, jack stands, lug wrench
Lift the vehicle and remove the wheels to access the brake assembly.
Inspect brake pads and rotors for signs of wear or overheating. Look for discoloration or excessive dust.
If the brake pads are worn or if there is evidence of overheating, replace them with quality OEM parts.
Reassemble the brake components and wheels, ensuring lug nuts are torqued to the manufacturer's specification.

4. Inspect for Foreign Objects

Tools Required: Flashlight, inspection mirror
Visually inspect the engine bay and undercarriage for any foreign objects that may be in contact with belts or other moving parts.
Remove any identified objects carefully to prevent further damage.
