While the drivers are not expected to be able to service a disabled braking system, you should be knowledgeable enough to identify if the brakes are not performing properly.

  1. Hydraulic brakes (with power assist):
    • With the engine stopped, pump the brake pedal several times to eliminate power assist.
    • Apply brakes moderately.
    • Start the engine (the pedal should drop slightly and stop).
    • If the pedal continues to drop or does not drop (no power assist) stop the engine. The vehicle should be taken out of service and the system inspected professionally.
  2. Hydraulic brakes (without power assist):
    • Apply brakes moderately and hold.
    • If the pedal shows a steady drop, the vehicle should be taken out of service and the system inspected professionally.
