Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, flashlight, safety gloves.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery before starting work on any electrical components.

2. Inspect and Replace Worn Belts

Inspect the Serpentine Belt:
- Remove the belt from the engine by loosening the tensioner pulley using a socket wrench.
- Check the belt for cracks or signs of wear.
Replace if Necessary:
- If the belt shows damage, replace it with a new one, ensuring it matches the manufacturer specifications.
- Reinstall the belt and ensure proper tension.

3. Check and Replace Damaged Hoses

Inspect Hoses:
- Visually examine all rubber hoses for cracks or bulges.
Replace if Necessary:
- If any hoses are damaged, remove the clamps and replace with new hoses. Ensure they are secured with clamps to prevent leaks.

4. Brake Inspection and Replacement

Inspect Brake Components:
- Remove the wheel to access brake pads and rotors.
- Check for excessive wear on pads and signs of overheating on rotors.
Replace if Necessary:
- If brake pads are worn thin, replace them with new pads.
- Resurface or replace the rotors if they show signs of heat damage.

5. Test and Reassemble

Reassemble all components, ensuring all fasteners are torqued to manufacturer specifications.
Reconnect the battery and start the vehicle.
Verify that no burning rubber smell persists and that all components function correctly.
