Air Brake System
m2 dm 09.01.000
A dual air brake system consists of two independent air systems
that use a single set of brake controls. Each system has its own reservoirs,
plumbing, and brake chambers. The primary system operates the service
brakes on the rear axle; the secondary system operates the service
brakes on the front axle. Service brake signals from both systems
are sent to the trailer.
Warning: Do not operate the vehicle with the front
brakes backed off or disconnected. Backing off or disconnecting the
front brakes will not improve vehicle handling and may lead to loss
of vehicle control, resulting in property damage or personal injury.
