against the top edge of the brake
release trim. Use masking tape to
securely hold down the template.
Note: Do not tape over the markings
on the template.
12. Before drilling, double check
to make sure there is enough room
behind where the Banks Brake Enable
Switch will be located. It may be
necessary to make minor adjustments
to the switch’s location, as needed.
Choose one of the hole locations that
you would like to drill. Using a ½” Unibit, center the bit onto the ½” drill
location on the template and slowly

drill through the panel. Remove and
discard the template and any plastic
Note: It is important that the hole
is drilled as close as possible to the
recommended location. The switch
may not clear the instrument panel
structure if the hole is shifted to
another location.
A pilot hole may be drilled first if a Unibit is unavailable. Use a drill bit smaller
than 1/2”.
13. Align the Banks Brake Enable
Switch label over the previously drilled
hole. Make sure the entire mounting
surface is clean and free of dirt and
oil before mounting the label. Clean
and dry as required using a cloth
dampened with rubbing alcohol or
similar cleaning solution.
CAUTION: Do not get any fluid
directly onto/into any electrical
equipment or equipment damage
may result.
14. Mount the Banks Brake Enable
Switch label onto the panel by peeling
off the protective backing from the
adhesive tape on the back of the
switch label. Hold the label against the
panel for approximately 20 seconds
while applying pressure to allow the
adhesive to properly adhere to the

Functional Testing
The Banks Brake has been designed for
your truck. It features:
• Quicker engine warm-ups.
• Compatible with cruise control.
• Compatible with Banks Diesel Tuners.
Note: The following testing should be
performed only after the vehicle has
been allowed to COMPLETELY COOL.
This test verifies the performance
of the warm-up feature of the Brake
System and must be performed with a
cold vehicle.
1. Verify that the Banks Brake Enable
Switch is in the “ON” position. The
Switch will light up.
2. Ensure that the accelerator pedal is
NOT depressed.
3. Start the engine and let it idle.
The Brake valve will close and can
be verified by the increased noise or
muffled sound of a restricted exhaust
pipe or by observing the Brake
actuator lever closing.
4. Slowly press the accelerator pedal.
The Brake valve will open. Release the
accelerator pedal and the Brake valve
will close.
Note: The engine speed (RPM) should
not exceed 1200 RPM prior to Brake
5. Allow the vehicle to reach normal
operating temperature. The Brake will
remain active until the vehicle reaches
approximately 175°F (79°C) engine
coolant temperature. Once the vehicle
warms up, the Brake will turn off.
Obtain a vehicle speed of
approximately 40 MPH (64 KPH) in an
area where speeds of this nature are
safe and traffic is light. Confirm that
the Banks Brake Enable Switch is in
the “ON” position. The Switch will be
lit up. Release the throttle. The brake
should activate and the vehicle will
begin to slow. Bring the vehicle to a
safe stop (using the vehicle’s hydraulic
brakes). Turn the Banks Brake Enable
Switch to the “OFF” position.
Once the vehicle has passed all of
the tests outlined in Steps 1-6, the
installation of the Banks Brake system
is complete and ready for years of
reliable service.

Safety and Operation/ Driving Tips
CAUTION: Your Banks Brake is
NOT a substitute for the hydraulic
brakes on your truck. The device
will not correct or compensate
for improperly maintained
hydraulic brakes. Also, please
be aware that your Banks Brake
is not designed to be used as a
parking brake or to bring your
vehicle to a complete stop. Your
Banks Brake is a supplementary
braking system designed to help
you slow down or to assist you
in maintaining a more constant
speed when descending a grade.
Remember that this Exhaust
Brake is first and foremost a
safety device and it is most
efficient when used to prevent,
rather than correct a runaway
vehicle condition.
The use of a Banks Brake does not
increase the load capacity of your
vehicle. Gross Combined Weight
Rating specifications should always
be adhered to. The Banks Brake will
allow you to slow your vehicle more
effectively within your vehicle’s weight
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. The
97232 v.3.0
Brake will also work with your cruise
control. When activated, the Brake will
be on when coasting and off when
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 back pressure being
introduced into the engine.
The Banks Brake features a user
selectable warm up mode. When
activated and the engine is cold
(below 175°F, 79°C), the Exhaust
Brake will activate to reduce the
amount of engine warm-up time
required. There may be an increase
in engine noise when the Brake is
closed. Once the vehicle reaches
operating temperature, the Brake will
open. The Brake will also open when
the accelerator pedal is depressed
at temperatures below 175°F (79°C).
This prevents soot build-up and keeps
the shaft assembly from sticking. It
eliminates the need for any additional
To activate the warm-up mode, put
the Enable Switch to the ON position.

If the Banks Brake does not pass
to function properly, re-check all
the connections per the installation
instructions. Make sure that electrical
connections are tight and secure and
that the vacuum hoses are not kinked or
If the Brake Enable Switch does not light
up within a few seconds, the following
diagnostic procedures can be carried out
to identify and correct the problem:
1. With key on and the engine off,
turn the Brake Enable Switch on. If the
Switch does not light up, make sure
the Switch is connected correctly and
check the fuse.
2. If the Enable Switch is lit solidly,
then inspect all the mechanical
components in the System. With the
engine cold and the hood up, have
someone start the engine. Make sure
the transmission is in neutral and
the parking brake is set. Watch the
actuator arm on the Brake housing.
It should move forward (closed).
Whenever the accelerator pedal
is pressed, the Brake should open
(actuator arm should move back
towards the firewall).
Checking the performance of the
vacuum pump:
WARNING: The Pump must never
be run open to the atmosphere,
as this will damage the Pump
diaphragm. The Pump must
always be connected to the
Vacuum Solenoid or it’s vacuum
nipple must be plugged. The
warranty on the Pump will be
voided if the Pump is allowed to
run open to the atmosphere.
With the vehicle safely in park and
the engine off, disconnect the 5⁄ 16”
hose from the Vacuum Solenoid (Port
1, Figure 8). Connect this hose to a
vacuum gauge while keeping the other
end connected to the Vacuum Pump.
Make sure the truck is in park and
start the engine. Measure the vacuum
at 1900 RPM. The Pump should
generate a minimum of 10 psi (20.4”
Hg) of vacuum. Replace the Vacuum
pump if necessary. After testing, turn
off the engine and disconnect the
vacuum gauge and reconnect the
5⁄ 16” hose to Port 1 on the Vacuum
Checking the operation of the
Exhaust Brake:
With the vehicle safely in gear, the
parking brake set, and the engine off,
disconnect the 7⁄32” hose connection
(Port 2, Figure 8) from the Vacuum
Solenoid. Connect this hose to a
vacuum tester and keep the other
end of the 7⁄32” hose connected to the
Exhaust Brake Actuator. As vacuum
is generated with the tester, the
Actuator should retract and rotate
the lever arm off it’s stop (as seen
in Figure 7). The lever arm should
travel 81.5 degrees without binding
or sticking. After testing, disconnect
the vacuum tester and reconnect the
7⁄32” hose to Port 2 on the Vacuum
If the Exhaust Brake is slow to open,
check the Vacuum Solenoid’s brass
filter. If it is dirty, clean or replace it.
