General InstallationPractices1. For ease of installation of yourBanks Brake, please read this 20-page Owner’s Manual before startingany work. Become thoroughlyfamiliar with all components andphases of the installation beforebeginning any work.

2. Inspect all components suppliedfor any foreign material that mayhave entered during shipping andhandling.

3. The installation should beperformed at a time when thevehicle has been allowed tocompletely cool. This installationrequires the installer to work nearsurfaces that may remain hot afterthe vehicle has been run. Failure toallow the vehicle to cool may result inpersonal injury.

4. Pay particular attention to therouting of wires. Keep them awayfrom exhaust heat, moving parts andsharp edges that may cause damage.Route or tie away from critical areasas required. Keep all wires aminimum of 6" from hot exhaustparts, 8" or more is recommendedwhenever possible.

Warning! Never work under anyvehicle supported only by a jackof any kind. DO NOT USE concreteblocks or other masonry itemsthat may collapse under thevehicle weight.

NOTE: If the vehicle has had the BanksMonster exhaust system P/N 48628,48629 and 48630 (without a 4-boltgasket flange) previously installed, itwill be necessary to use the optionalBanks Flange Adapter Kit (P/N 55246)to install the Banks Brake.

On vehicles with a catalyticconverter: Install the Banks Brakeassembly onto the 4-bolt flange usingthe factory studs and previouslyremoved nuts. Install the suppliedexhaust gasket between the BanksBrake and the 4-bolt exhaust flange.Snug the nuts up and adjust thebrake housing to align the two flangehalves with each other. Evenly torquethe flange nuts to 50 ft-lbs (seeFigure 16).

CAUTION: The following stepinvolves cutting a stainless steeltube. Safety glasses should beworn during any cuttingoperation, and care should betaken to avoid injury due to sharpedges and burrs.

58. The exhaust brake outlet pipemust be trimmed to the properlength prior to installation. Figure 17illustrates the proper trim dimensionsdepending on the cab/bedconfiguration of the vehicle. The pipecan be trimmed with a hacksaw andthe end of the pipe should be de-burred to prevent the possibility ofinjury due to sharp edges.

59. Install the supplied V-band clampon the outlet of the brake housing.Do not tighten clamp at this time.

60. Slide the supplied exhaust bandclamp over the inlet to theintermediate pipe. Do not tightenthe clamp at this time.

61. Slide the outlet of the exhaustbrake outlet pipe into the slip joint onthe intermediate pipe.

NOTE: Disengaging the intermediatepipe and tailpipe hangers from theirrubber mounts may ease installationof the exhaust brake outlet pipe.Spray lubricant (i.e. WD-40, etc.) anda pry bar will make disengagement ofthe hangers a much simpler task.

62. NOTE: Steps 61-66 areprovided to adapt the Banks Brake toa factory exhaust configuration. If thesystem is being installed on a vehiclethat is already equipped with a BanksMonster Exhaust system, skip toStep 67.

63. Mark a line 5" back from the 4-bolt exhaust flange interface asshown in Figure 18. Using ahacksaw or similar cutting tool,cut the pipe at the previouslymarked line.

64. Remove the four (4) retainingnuts (retain for re-use) from the 4-bolt

flange and remove rearmost flangeand the gasket. Both pieces (gasketand pipe) may be discarded.

65. Place a mark on the inlet to theintermediate pipe that is 3" from thepreviously cut edge of the pipe.

NOTE: This mark is used in asubsequent step to ensure properengagement of the exhaust brakeadapter pipe.

66. Install the supplied gasket ontothe 4-bolt flange. Install the BanksBrake onto the 4-bolt flange asshown in Figure 16 using thepreviously removed bolts, attach theBanks Brake to the flange. Torque thenuts to 30 ft-lbs.

intermediate pipe. Do not tighten theclamp at this time.

68. Slide the outlet of the providedexhaust brake outlet pipe onto theintermediate pipe.

NOTE: Disengaging the intermediatepipe and tailpipe hangers from theirrubber mounts may ease installationof the exhaust brake outlet pipe. Spraylubricant (i.e. WD-40, etc.) and a pry barwill make disengagement of thehangers a much simpler task.

69. Engage the exhaust brake outletpipe in the V-band clamp. Snug theclamp and ensure that the pipe iscentered on the V-band flange on thebrake housing. Torque the V-bandclamp to 12 ft-lbs.

70. Adjust the engagement of the slip joint until the hangers on theintermediate pipe and tailpipe arepositioned slightly forward as shown in Figure 19. Position the band clampas shown in Figure 20 and torquethe clamp to 35 ft-lbs.

NOTE: On vehicles with factory exhaust,the edge of the exhaust brake outletpipe should be lined up with the markmade in Step 63. However, this jointcan be adjusted in or out approximately1⁄4" as required to properly adjust theexhaust hangers.

71. Install the pneumatic line intothe pneumatic fitting located on therear of the brake actuator cylinder.See Figure 21. NOTE: The hose shouldbe trimmed as required to allow thehose to follow the torsion bar crossmember and then gently arc towardsthe actuator. Retain the remaining hosefor use on the remote vent line. Do notallow hose to touch exhaustcomponents, otherwise it may bedamaged by the heat.

72. Install one end of the remainingpneumatic line into the pneumaticfitting on the forward end of thebrake actuator cylinder.

73. Route the line across the torsionbar cross member above thepreviously installed line. Using thesupplied tubing clamps and selfthreading 1⁄4-20 bolts, mount thepneumatic hose to the torsion barcross member as shown in Figure 15. NOTE: The self-threadingbolts require a 7⁄32" pilot hole to bedrilled for proper thread formation.

NOTE: Be sure to route all plastic linesaway from exhaust components. Ifplastic hose rests on exhaust or

NOTE: The following testing should beperformed only after the vehicle hasbeen allowed to COMPLETELY COOL.This test verifies the performance ofthe warm-up feature of the brakesystem and must be performed witha cold vehicle.

77. Verify that the Banks BrakeActivation Switch is in the “OFF”position.

78. Ensure that the acceleratorpedal is NOT depressed. Turn theignition key to the “ON” position. Thegreen LED on the Computerized BrakeController (CBC) should light up andthe air compressor should run forapproximately 2 seconds beforeturning off.

79. Slowly press the acceleratorpedal. The green LED should turn offalmost immediately (very littlethrottle movement) and the aircompressor panel should vent theair from the brake actuator. Releasethe accelerator pedal and the greenLED should again light up and thecompressor should run forapproximately 2 seconds and thenshut off. Repeat this cycle a fewtimes to verify CBC function.

80. Start the engine and let it idle.The brake valve will close and can beverified by the muffled sound of arestricted exhaust pipe.

81. Slowly press the acceleratorpedal The green LED should turn offalmost immediately (very littlethrottle movement) and the aircompressor panel should vent the airfrom the brake actuator and thebrake valve should open. Release theaccelerator pedal and the green LEDshould again light up and thecompressor should run forapproximately 2 seconds and thenshut off. Repeat this cycle a fewtimes to verify CBC function. NOTE:The engine speed (RPM) should notexceed 1200 rpm prior to brakedisengagement.

82. Allow the vehicle to reachnormal operating temperature. Thebrake will remain active until thevehicle reaches approximately 125°Fengine coolant temperature(measured with a Tech II scan tool).Once the vehicle warms up, the brake will turn off.

83. Re-install the lower dash panel.

NOTE: Once the vehicle has passed the initial functional tests outlined inSteps 77-82 the vehicle can bedriven in order to complete therequired functional testing.

84. Obtain a vehicle speed ofapproximately 40-45 mph in an areawhere speeds of this nature are safeand traffic is light. Turn the Banks

Brake activation switch to the “ON”position. Release the throttle. Thebrake should activate and the vehiclewill begin to slow. Bring the vehicleto a safe stop (using the servicebrakes). As the vehicle speed dropsbelow approximately 15 mph thebrake should turn off. Turn the BanksBrake activation switch to the “OFF”position

85. Obtain a vehicle speed ofapproximately 40 mph in an areawhere speeds of this nature are safeand traffic is light. Set the cruisecontrol to 40 mph. Activate the BanksBrake by placing the activationswitch in the “ON” position. Thecruise control should disengage andthe vehicle should begin to slow.

86. Turn the Banks Brake activationswitch to the “OFF” position. Activatethe cruise control and set it forapproximately 40 mph. Press on the brake pedal. The cruise control should deactivate.

NOTE: Once the vehicle has passed all of the tests outlined in Steps 77-86,the installation of the Banks Brakesystem is complete and ready foryears of reliable service

Caution: Your Banks Brake is NOT a substitute for the hydraulicbrakes on your truck. The devicewill not correct or compensate forimproperly maintained hydraulicbrakes. Also please be aware thatyour Banks Brake is not designedto be used as a parking brake orto bring your vehicle to a completestop.Your Banks Brake is a

supplementary braking systemdesigned to help you slow downor to assist you in maintaining amore constant speed whendescending a grade. Remember thatthis exhaust brake is first andforemost a safety device and it ismost efficient when used toprevent, rather than correct arunaway vehicle condition.

The use of a Banks Brake does notincrease the load capacity of yourvehicle. Gross Combined WeightRating specifications shouldalways be adhered to. The BanksBrake will allow you to slow yourvehicle more effectively withinyour vehicle’s weightspecifications.

-END, SECTION 4-

Section 4SAFETY

96994 v.5.0 17

Use your Banks Brake to assist inslowing your vehicle while travelingdown grades. To activate the brake,flip the switch to the “ON” position.With the switch on, the brake will beactive anytime that your foot is noton the accelerator pedal. Note thatcruise control will be cancelled if it isactive at the time the Banks Brake isengaged.

When alternating between brakingactivity and acceleration, it is goodpractice to allow a minimum of onesecond to elapse after the brakehas been disabled or the throttle isapplied before reaching full throttleacceleration. This allows enough timefor the brake valve to fully open andeliminates the possibility of excessexhaust backpressure being introducedinto the engine.

If your vehicle is equipped with anautomatic transmission, your BanksBrake can be used with thetransmission in 5th, 4th, 3rd or 2ndgear. The transmission should beplaced in “TOW/HAUL” mode anytimethe brake is going to be used.TOW/HAUL mode holds the torqueconverter clutch locked when thebrake is active and will increasebrake performance greatly. The engineshould be downshifted to maintain ahigh engine speed (brake performanceis optimal above 2000 rpm).

If your vehicle is equipped with amanual transmission, it should alsobe downshifted to maintain a highengine speed when the brake isactive.

When the engine is cold (below125°F) the exhaust brake will activateto reduce the amount of warm-up

time required. Once the vehiclereaches operating temperature thebrake will open. This cold start brakeactivation also serves as amaintenance cycle, which helpsprevent soot build-up and keeps theshaft assembly from sticking. Thisprocess is automated andeliminates the need for any additionalmaintenance.

If it becomes necessary to removethe CBC from the vehicle, a by-passplug has been provided to install inits place. If the CBC is removedwithout being replaced by the by-pass plug, the vehicle will idle poorlyand set a diagnostic code. The CBCshould only be removed when theignition switch is in the “OFF”position.
