3 Braking performance
Perform braking tests in a safe place. After check-
ing that warning lamp or is not illuminated,
drive the vehicle at a low speed to make sure that
braking power is sufficient and even. If braking
seems in any way abnormal, operating the vehicle
could be dangerous. Ask an authorized dealer for a
more thorough inspection.
Use the air pressure gauge to check compressed
air pressure. The gauge should indicate a pressure
in range .
Also, make sure that the air pressure builds up at
the proper rate. This can be checked as follows:
1. Set the parking brake and stop the engine.
2. Open the drain cock to release all compressed
air from the air tank.
3. Start the engine and run it at idling speed while
timing how long it takes for the pressure to
reach 100 psi. The time should be as indicated
below.
