Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness; replace if worn down (less than 3mm).
3. Check rotors for scoring or warping; replace if necessary.
4. Reassemble the wheel and torque lug nuts to manufacturer specifications (usually 80-100 ft-lbs).

3. Check Electrical Systems

Sub-steps:
1. Inspect wiring harnesses for signs of damage, fraying, or melting.
2. Tighten any loose connections and replace damaged wiring.
3. Test all electrical components to ensure they are functioning correctly.

4. Examine Drive Belt

Sub-steps:
1. Locate the drive belt and inspect for cracks, fraying, or signs of melting.
2. If damaged, remove the old belt and install a new one, ensuring proper routing.
3. Check tensioner and pulleys for proper operation and replace if necessary.
