PARKING BRAKE
Freightliner
®
Chassis
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
™
, the
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, Medium, or High
setting. This turns the power-producing diesel
engine into a power-absorbing compressor,
which provides effective deceleration of the
