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

2. Brake Inspection and Replacement

Inspect Brake Components:
- Remove the wheel using a lug wrench.
- Inspect the brake pads for wear; replace if less than 3mm thick.
- Check the rotors for scoring or discoloration due to overheating; replace if necessary.
Replace Brake Pads:
- Remove the caliper bolts and lift the caliper away from the rotor.
- Remove old brake pads and install new ones, ensuring they are seated correctly.
- Reattach the caliper and torque the bolts to manufacturer specifications (typically around 25-35 Nm).

3. Electrical Inspection and Repair

Inspect Wiring:
- Look for damaged or burnt wiring under the hood and around the battery.
- Repair or replace damaged wiring as necessary.
Check Fuses:
- Locate and inspect fuses related to the affected systems (e.g., lighting, engine management).
- Replace any blown fuses with the correct amperage.

4. Engine Inspection

Check for Oil/Coolant Leaks:
- Inspect the engine for signs of oil or coolant leaks that could cause burning.
- Clean any spilled fluids and replace damaged gaskets if needed.
Check Engine Cooling:
- Ensure that the cooling system is functioning properly, including the water pump, thermostat, and radiator.
