Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool, flashlight.
Steps:
1. Remove the engine cover (if applicable) by unscrewing any fasteners holding it in place.
2. Locate the serpentine belt and use the belt tensioner tool to relieve tension on the belt.
3. Remove the old serpentine belt from the pulleys.
4. Inspect each pulley for damage or wear, replacing any faulty components.
5. Install the new serpentine belt following the routing diagram (usually found on a sticker under the hood).
6. Recheck the tension and ensure the belt is properly seated on all pulleys.

3. Inspect and Replace Brake Components

Tools Required: Jack, jack stands, socket set, torque wrench, brake cleaner.
Steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect the brake pads for thickness; replace if worn down (less than 3mm).
4. Check the brake rotors for grooves or warping; resurfacing may be needed if damaged.
5. Clean the brake components with brake cleaner before reassembly.
6. Reassemble the brakes and wheel, ensuring all bolts are torqued to the manufacturer's specifications.
