Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, socket set, brake cleaner, coolant, jack stands, and safety gloves.
Park the vehicle on a flat surface and engage the parking brake. Allow the engine to cool down before proceeding.

2. Address Fluid Leaks

Inspect and Clean: Clean any spilled fluids with brake cleaner and determine their source.
Repair Leaks: Replace any damaged gaskets, seals, or components that are leaking.

3. Brake Inspection and Maintenance

Remove Wheels: Jack up the vehicle and remove the wheel covers/tires to access brake components.
Inspect Brake Pads and Rotors: Check thickness of brake pads; replace if they are worn down to the minimum thickness. Evaluate rotors for overheating or warping.
Replace Brake Components: If worn or damaged, replace brake pads and rotors. Ensure to torque bolts to manufacturer specifications (typically around 80-100 ft-lbs for brake caliper bolts).

4. Electrical Inspection

Check Wiring: Inspect wiring for any signs of damage or burning. Repair or replace any frayed wires.
Re-secure Loose Connections: Ensure all electrical connections are tight and secure.

5. Final Assembly and Fluid Check

Reinstall Wheels: Replace wheels and ensure they are tightened to the correct torque specifications.
Check Fluid Levels: Ensure engine oil, coolant, and brake fluid levels are adequate. Top off if necessary.
