Use the parking brake knob to apply the park
brake whenever the vehicle is parked.
Never try to drive the vehicle with the parking
brake applied. This can cause excessive wear on
the brakes and may damage the transmission.
NOTE: It is normal to hear an occasional burst
of air pressure from the rear of the
vehicle. This is an automatic moisture
purging feature of the air brake system.
See the Brakes section of your chassis
manual for instructions on periodic
draining of brake air tank.

ENGINE BRAKE SYSTEM

®
Freightliner Chassis
Many large diesel trucks are equipped with a
compression release engine brake system,
commonly referred to as a "jake brake"– so
named for Jacobs Vehicle Systems
originator of this type of braking system.
The engine brake is a device mounted on top
of the diesel engine that temporarily changes the
timing of the exhaust valves, momentarily
shutting down either three cylinders or all six
cylinders, depending on Low or High setting.
This turns the power-producing diesel engine
into a power-absorbing compressor, which
provides effective deceleration of the vehicle.
Combined with use of the chassis air brakes, the
engine brake delivers a substantial degree of
braking power.
on the lower left side of the dash. Press and
release the ON side of the switch to activate the
engine brake system. The engine brake will
operate whenever you let up on the throttle pedal
while the switch is ON.
