Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake cleaner, safety goggles, gloves.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before performing any inspections.

2. Addressing Brake Issues

Lift the Vehicle: Use a jack and jack stands to elevate the vehicle safely.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect Brake Components:
- Check brake pads for wear; replace if they are worn down to 3mm or less.
- Inspect rotors for scoring; replace if damaged.
Clean Components: Use brake cleaner to remove dust and debris from pads and rotors.
Reassemble: Reinstall the wheel and torque the lug nuts to the manufacturer's specification (typically 100-120 ft-lbs).

3. Addressing Engine Issues

Check for Leaks: Inspect the engine bay for oil or coolant leaks that may cause burning.
Replace Affected Components:
- If oil is leaking, replace damaged gaskets or seals.
- If coolant is leaking, replace hoses or the water pump as needed.
Inspect Belts and Hoses: Look for cracks or wear. Replace any damaged components.
Clean Electrical Connections: Ensure all electrical connections are tight and free from corrosion.
