Solution

1. Preparation

Gather tools and necessary parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical short circuits.

2. Inspect and Address Brake Components

Check Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Inspect brake pads for excessive wear; replace if less than 1/8 inch thick.
- Inspect rotors for signs of scoring or overheating; machine or replace as needed.
Replace Brake Pads:
- If pads need replacing, remove the caliper bolts and slide the caliper off.
- Remove old pads and install new ones, ensuring they are seated properly.
- Reattach the caliper and ensure bolts are torqued to manufacturer specifications.

3. Inspect Electrical Components

Check Wiring and Connectors:
- Inspect wiring harnesses for damaged insulation or burnt areas.
- Repair or replace any damaged wiring and ensure connections are secure.

4. Fluid Check and Replacement

Check and Replace Engine Oil & Coolant:
- Check the engine oil level and condition; replace if it appears burnt or low.
- Inspect the coolant reservoir; replace coolant if it’s low or discolored.

5. Final Assembly

Reassemble any components removed during inspection.
Reconnect the battery and ensure all connections are secure.
Conduct a visual inspection for any leftover tools or parts.
