Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, OBD-II scanner, infrared thermometer, fluid catch pan.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Addressing Fluid Leaks

Sub-steps:
1. Identify the source of any fluid leaks (oil, coolant, brake fluid).
2. For oil leaks, replace gaskets or seals as necessary.
3. If coolant is leaking, replace the radiator or hoses if damaged.
4. For brake fluid leaks, replace damaged brake lines or fittings.

3. Brake Inspection and Repair

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if they are less than 3mm thick.
3. Check rotors for overheating signs; replace if warped or damaged.
4. Reassemble the brake components and ensure proper torque on bolts (manufacturer specifications).

4. Electrical Wiring Repair

Sub-steps:
1. Locate any damaged wiring and disconnect the affected circuit.
2. Use electrical tape or heat shrink tubing to repair minor damage, or replace the wire completely if severely damaged.
3. Ensure all connections are secure and insulated.

5. Engine Coolant and Oil Maintenance

Sub-steps:
1. Drain any contaminated coolant and replace with fresh coolant (use manufacturer-recommended type).
2. Change the engine oil and oil filter if oil is low or contaminated.
3. Monitor for any signs of leaks after refilling fluids.
