  - Check brake calipers for leaks or overheating.
  - Reassemble the wheel and lower the vehicle.
- Belts and Hoses:
  - Inspect serpentine belts and hoses for cracks or deterioration.
  - Replace any damaged belts or hoses using the manufacturer’s specifications for torque and positioning.

3. Electrical System Check

Sub-steps:
- Use a multimeter to test the battery and alternator voltage.
- Inspect wiring harnesses for damage or fraying. Replace any damaged wires.
- Reconnect the battery after all inspections and repairs are done.

4. Fluid Replacement

Sub-steps:
- If transmission fluid is burnt, drain and replace it with the manufacturer-recommended fluid.
- Inspect other fluids (engine oil, coolant) and top up or replace as needed according to the service manual.

5. Final Checks

Perform a visual inspection of all repaired areas.
Reconnect any components or covers that were removed during repairs.
