you can increase or decrease the braking resistance for the type of driving you plan to do for
80
How can you check slack adjusters?
Turn off the parking brakes so you can move the slack adjusters. Use gloves and pull hard on each slack adjuster that you can reach. If a slack adjuster moves more than about one inch where the push rod attaches to it, it probably needs adjustment. Adjust it or have it adjusted.
81
How can you test the low pressure warning | signal?
Shut the engine off when you have enough air pressure so that the low pressure warning signal is not on. Turn the electrical power on and step on and off the brake pedal to reduce air tank pressure. The low air pressure warning signal must come on before the pressure drops to less than 60 psi in the air tank (or tank with the lowest air pressure, in dual air systems).
82
How can you check that the spring brakes | come on automatically?
Continue to fan off the air pressure by stepping on and off the brake pedal to reduce tank pressure.
83
