Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Visually inspect the brake pads for wear; replace if less than 1/8 inch remaining.
- Check the rotor for scoring or overheating discoloration.
Replace Brake Pads (if necessary):
- Remove the caliper bolts using a wrench.
- Slide the caliper off and replace the pads.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 25-30 Nm).

3. Address Engine Issues

Inspect Belts and Hoses:
- Check for fraying or cracks in belts and replace if found.
- Inspect hoses for leaks or bulges; replace any that are damaged.
Check for Oil Leaks:
- Clean any oil residue around the engine.
- Tighten oil pan bolts or replace gaskets if necessary.

4. Electrical System Check

Inspect Wiring and Connectors:
- Look for melted or frayed wires in the engine compartment.
- Replace any damaged wiring or connectors.

5. Final Assembly

Reconnect the battery.
Replace the wheel and lower the vehicle.
Ensure all components are securely fastened.
