  2. Inspect brake pads and rotors for wear or damage.
  3. If necessary, replace the brake pads and resurface or replace the rotors.
  4. Reinstall wheels and lower the vehicle.
  5. Pump the brake pedal to restore brake pressure.
3. Tire Maintenance
Tools Required:
  • Tire pressure gauge
  • Tire tread depth gauge

Repair Instructions:

  1. Adjust tire pressures to the recommended PSI.
  2. Rotate tires based on the maintenance schedule (typically every 5,000 to 7,500 miles).

5. Coolant System Maintenance
Tools Required:
  • Coolant pressure tester
  • Funnel

Repair Instructions:

  1. If the coolant is low, top it off with the appropriate type of coolant.
  2. Inspect hoses and clamps for leaks; replace any damaged hoses.
  3. If overheating persists, perform a coolant flush to remove debris and contaminants.
