Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Worn Belts

Sub-steps:
1. Remove any engine covers or components obstructing access to the serpentine belt.
2. Inspect the serpentine belt for cracks, fraying, or signs of wear.
3. If the belt is damaged, use a socket set to loosen the tensioner and remove the old belt.
4. Install a new serpentine belt, ensuring it is properly routed through all pulleys.
5. Reattach any engine covers removed during inspection.

3. Check and Replace Damaged Hoses

Sub-steps:
1. Inspect all rubber hoses leading to and from the engine for cracks or leaks.
2. If any hoses are damaged, use a hose clamp or pliers to remove the old hose, and replace it with a new one.
3. Ensure all connections are secure and there are no leaks after replacement.

4. Brake Component Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect brake pads for wear; if they are worn down to the backing plate, they need replacement.
4. Check rotors for overheating signs; if they are warped or excessively worn, they should be resurfaced or replaced.
5. Reassemble the wheel and lower the vehicle.
