Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, socket set, multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Inspect and Repair Fluid Leaks

Sub-steps:
- Check for oil or coolant leaks around the engine and transmission.
- If leaks are found, clean the affected area and replace the faulty seals or gaskets.
- Top off any low fluid levels with the appropriate type of oil or coolant.

3. Replace Worn Belts and Hoses

Sub-steps:
- Inspect belts for fraying or cracking and hoses for leaks or bulges.
- If any damage is found, remove the old belt or hose using a socket set.
- Install new components, ensuring proper tension on belts and secure connections on hoses.

4. Address Brake Issues

Sub-steps:
- Inspect brake pads and rotors for excessive wear.
- If the brake pads are worn, replace them according to manufacturer specifications.
- Ensure that calipers are functioning correctly and not sticking.
