Solution

1. Preparation

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

2. Inspect and Repair Brake Components

Remove the Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel lug nuts using a socket set and take off the wheel.
Examine Brake Pads and Rotors:
- Check the brake pads for excessive wear; replace if below recommended thickness (usually 3mm).
- Inspect the brake rotors for signs of warping or overheating; replace if necessary.
Clean and Lubricate:
- Clean the caliper and pads with brake cleaner.
- Apply brake grease to the back of the pads and on the caliper pins.
Reassemble:
- Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
- Lower the vehicle.

3. Address Engine or Electrical Issues

Inspect Wiring and Connectors:
- Visually examine all wiring harnesses for signs of burning or damage.
- Replace any burnt wires or connectors.
Check Fluid Levels:
- Ensure engine oil, coolant, and transmission fluid levels are adequate; top off if low.
- Inspect for any leaks that could be causing burning smells.
Reattach Battery:
- Reconnect the battery terminals securely.
