Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues during repairs.

2. Address Fluid Leaks

If oil or coolant leaks are found:
1. Identify the source of the leak (e.g., gasket, seal).
2. Replace the faulty gasket or seal using appropriate tools (socket set, torque wrench).
3. Refill the fluid to the correct level.

3. Replace Damaged Components

If burnt wiring or components are identified:
1. Remove any damaged wiring or components by disconnecting connectors and unbolting.
2. Install new wiring or components as per manufacturer specifications, ensuring proper connections.
3. Use electrical tape or heat shrink to secure connections and prevent future issues.

4. Brake Inspection and Replacement (if necessary)

If brake components are worn:
1. Remove the wheel to access the brake assembly.
2. Inspect pads and rotors; replace if worn down (new brake pads and rotors may be required).
3. Reassemble the brake assembly and wheel.

5. Final Checks

Reconnect the battery and start the vehicle.
Monitor for any persistent smells or warning lights.
