the Anti-Lock Brake System (ABS). The brake system also
includes foundation brakes made up of slack adjusters, S-cams,
brake chambers, and brake shoes or pads.
Air system
The trailer's air system is supplied by the tractor brake system
and it consists of plumbing throughout the trailer, the gladhands
for both the "Service (blue) and Emergency (red)" lines, the air
tank, the suspension, and the brake valves. Refer to the following
diagram for each component of the air system and its

NOTE
• The supply system from the tractor is connected to the red
gladhand (emergency supply) and provides a constant air supply
that releases the parking brakes and maintains consistent air
pressure in the air tank.
• The service system from the tractor is connected to the blue
gladhand (service supply) and provides a signal for trailer brake
activation when the tractor brakes are applied.
• The supply system (emergency supply) allocates air for releasing
the spring brakes before charging the air tank and supplying the
suspension system.
