The rear brakes on the PowerGlide chassis are also used as the parking brakes. This provides you the holding
power of two large drum brakes to prevent your coach from rolling, even when fully loaded on a 20% grade.
A decrease in air pressure while driving will not cause an immediate loss of brakes. If a significant leak develops
in the air system, at approximately 60 PSI you will be alerted by a lamp on the instrument panel, and by an
audible alarm. As you apply the brakes, the air supply holding the park brakes in the released position will
gradually be depleted. When system pressure drops to approximately 40 PSI the rear brakes will set. This allows
you sufficient time to pull over to the side of the road.
