Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel covering the brakes using a socket set.
2. Inspect the brake pads for thickness; replace them if they are below the manufacturer's specifications (typically less than 3mm).
3. Check brake rotors for scoring; if necessary, resurface or replace them.
4. Reinstall the wheel and torque it to the manufacturer’s specifications (usually around 80-100 ft-lbs).

3. Check and Repair Wiring

Sub-steps:
1. Inspect all visible wiring for fraying or damage.
2. Look for any burnt connectors or melted insulation.
3. Replace any damaged wires with the appropriate gauge wire and reconnect securely.
4. Apply electrical tape or heat shrink tubing to secure connections.

4. Battery Inspection and Maintenance

Sub-steps:
1. Inspect the battery terminals for corrosion.
2. Clean terminals with a mixture of baking soda and water if corrosion is present.
3. Ensure battery connections are tight and secure.
4. If overheating is suspected, replace the battery if necessary.
