Use your Banks Brake to assist in
slowing your vehicle while traveling
down grades. To activate the brake,
flip the switch to the “ON” position.
With the switch on, the brake will be
active anytime that your foot is not
on the accelerator pedal. Note that
cruise control will be cancelled if it is
active at the time the Banks Brake is
engaged.
When alternating between braking
activity and acceleration, it is good
practice to allow a minimum of one
second to elapse after the brake
has been disabled or the throttle is
applied before reaching full throttle
acceleration. This allows enough time
for the brake valve to fully open and
eliminates the possibility of excess
exhaust backpressure being introduced
into the engine.
If your vehicle is equipped with an
automatic transmission, your Banks
Brake can be used with the
transmission in 5th, 4th, 3rd or 2nd
gear. The transmission should be
placed in “TOW/HAUL” mode anytime
the brake is going to be used.
TOW/HAUL mode holds the torque
converter clutch locked when the
brake is active and will increase
brake performance greatly. The engine
should be downshifted to maintain a
high engine speed (brake performance
is optimal above 2000 rpm).
If your vehicle is equipped with a
manual transmission, it should also
be downshifted to maintain a high
engine speed when the brake is
active.
When the engine is cold (below
125°F) the exhaust brake will activate
to reduce the amount of warm-up
time required. Once the vehicle
reaches operating temperature the
brake will open. This cold start brake
activation also serves as a
maintenance cycle, which helps
prevent soot build-up and keeps the
shaft assembly from sticking. This
process is automated and
eliminates the need for any additional
maintenance.
If it becomes necessary to remove
the CBC from the vehicle, a by-pass
plug has been provided to install in
its place. If the CBC is removed
without being replaced by the by-
pass plug, the vehicle will idle poorly
and set a diagnostic code. The CBC
should only be removed when the
ignition switch is in the “OFF”
position.
