Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool before starting any inspection.
Gather tools and parts for potential repairs.

2. Inspect and Clean Brake Components

Tools Required: Jack, jack stands, lug wrench, brake cleaner, socket set.
Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the brake components.
- Inspect brake pads for wear. If they are worn down to the indicator or below specifications, replace them.
- Check the rotors for warping or damage. Replace if necessary.
- Clean any debris from the caliper and rotor surfaces with brake cleaner.
- Reassemble the brake components and wheel, ensuring all fasteners are torqued to manufacturer specifications (typically 80-100 ft-lbs).

3. Inspect Electrical Connections

Tools Required: Multimeter, electrical cleaner, wire brush.
Inspect all visible wiring for insulation damage or burnt connections.
- Use a multimeter to check for continuity in damaged wires.
- Clean any corroded connections with electrical cleaner and a wire brush.
- Repair or replace damaged wiring and connectors as necessary.

4. Check Cooling System

Tools Required: Coolant tester, funnel.
Inspect coolant levels in the reservoir. If low, top off with the manufacturer-recommended coolant.
- Check for leaks in hoses or at the water pump. Repair or replace leaking components.
