Trailer Air Supply Valve
The red octagonal-shaped knob operates the trailer
air supply valve, which charges the trailer air supply
system and releases the trailer spring parking
brakes. See
After the vehicle and its air hoses are connected to a
trailer and the pressure in the air system is at least
65 psi (447 kPa), push the trailer air supply valve
knob in (and leave it in) to charge the trailer air sup-
ply system and release the trailer spring parking
brakes. Pull the trailer air supply valve out before
disconnecting a trailer or when operating a vehicle
without a trailer.
Trailer Brake Lever
The trailer brake lever is used to apply the trailer ser-
vice brakes without applying the truck or tractor ser-
vice brakes. It is usually mounted on the right-hand
control panel. Move the lever down to apply the
trailer brakes; move the lever up to release the trailer
brakes. The lever will automatically return to the up
position when it is released. See
. The lever
can be partially or fully applied, but in any partially on
position it will be overridden by a full application of
the service brake pedal.
Antilock Braking System
The Meritor
™
WABCO® Antilock Braking System
(ABS) passively monitors vehicle wheel speed at all
times, and controls wheel speed during emergency
stops or wheel lock situations.
During emergency or reduced-traction stops, fully
depress the brake pedal until the vehicle comes to a
safe stop.
Do not pump the brake pedal
. With the
brake pedal fully depressed, the ABS will control all
wheels to provide steering control and a reduced
braking distance.
