Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is in gear or has the parking brake engaged.
Disconnect the battery to prevent accidental electrical shorts during inspection.

2. Inspect and Replace Belts

Tools Required: Socket set, torque wrench
Locate the serpentine belt and perform a visual inspection for any cracks, fraying, or glazing.
If the belt is damaged, remove it by loosening the tensioner pulley and sliding the belt off.
Install the new belt following the diagram usually located on the engine compartment.
Ensure proper tension is achieved and torque the tensioner according to manufacturer specifications.

3. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, lug wrench
Inspect each tire for uneven wear patterns or visible damage.
If tires are worn, remove the affected tire by loosening the lug nuts with a lug wrench.
Replace with a new tire, ensuring to mount it correctly and tighten lug nuts to the specified torque.
Check tire pressures and adjust them to the recommended PSI.

4. Brake System Check

Tools Required: Brake cleaner, socket set
Inspect brake pads and calipers for wear. If pads are worn below manufacturer specifications, replace them.
Check caliper movement; if it appears stuck, lubricate or replace as necessary.
Reassemble the brake components and test for proper function.
