Banks Brake® '04.5-07

('04.5-07; automatic transmissions only)
A total system solution with enhanced transmission control
for exhaust braking, Banks' direct-mount, no-maintenance exhaust brake has electronics that monitor critical engine and transmission parameters to maximize braking efficiency. It dramatically cuts downhill speeds without using the wheel brakes. This keeps brakes cool and ready for emergencies, and saves thousands in brake maintenance. Optimizes exhaust flow when not engaged. Easy install; needs no drilling, cutting or modifications to stock wiring.

Computerized Brake Controller and SmartLock (CBC)

Computerized brake control (CBC) and SmartLock are included.
CBC automatically senses throttle position, controls brake engagement and cuts out annoying brake noises. Fast warm-up function prolongs brake durability, and automated brake disengagement at low speed smoothes stop-and-go driving. Banks SmartLock locks the torque converter & raises line pressure to smoothly reduce vehicle speed and safeguard the transmission.

 

Includes:
Cast, large-bore brake housing assembly; High-force 4-1/4" vacuum actuator; Belt-driven vacuum pump with serpentine belt for quiet operation; Computerized Brake Controller/SmartLock; Large butterfly valve with super-alloy shaft-and-bearing system; Wire loom; Mounting hardware.

Test Setup

An ’06 Dodge Cummins pickup was equipped with the Banks DynaFact® data acquisition system to measure vehicle speed, engine RPM, exhaust backpressure, transmission line pressure and braking horsepower.

Test runs on a 7% grade in the vicinity of Southern California's daunting Cajon Pass were done with the gear selector in both Drive and 2nd. Tow/Haul mode was used in all cases, per Dodge’s recommendations. 55 mph was established at the top of the hill, and the foot brake was applied only if it became necessary to keep the vehicle at a safe speed (no greater than 65 mph). Multiple configurations were tested: stock, Banks Brake with Computerized Brake Controller and SmartLock® (CBC), PacBrake, Jacobs and BD.

All of the brakes tested were a direct mount configuration. Each of the competitive brakes was controlled by the vehicle ECM (an option that became available starting in the 2006 model year). In addition to road testing, flow bench testing was conducted on each of the brake assemblies.

Banks Brake for '04.5-07 Dodge Cummins tested on 2006 crewcab short bed with 48RE automatic transmission at 7% grade; Banks data-acquisition system measured drop in downhill speed by 38% without using wheel brakes

Test Results

Gear Starting Speed Speed without Banks Brake Speed with Banks Brake
3rd 55 mph 65+ mph
(excessive use of foot brakes required)
62 mph
(no foot brakes)
2nd 55 mph 60+ mph
(use of foot brakes required)
37 mph
(no foot brakes)
Stock
  • Excessive use of foot brake required during descents in Drive: indication of possible runaway condition
  • Heavy use of foot brake required in 2nd gear to prevent excessive redlining & consequent engine damage

Banks Brake with CBC and SmartLock®
  • Smooth, controlled downhill descents
  • The only exhaust brake that didn’t require use of the foot brake in Drive
  • Highest peak braking horsepower
  • Immediate response
  • Superior airflow with brake open
  • By far, the quickest braking response time
  • Transmission line pressure around 133 psi during descent
    • This added line pressure keeps transmission clutches firmly applied
    • Protects the transmission
    • Over 50% more protective line pressure than the others provide
  • Vacuum pump produces no audible noise over normal engine sound

BD Brake
  • Uses a noisy electric pressure pump
  • Insufficient braking power: had to use foot brake during descents in Drive
  • Slow reaction time
  • Weakest of all exhaust brakes tested
  • Doesn’t operate in 1st gear
  • More restrictive when open; hurts performance
  • Automatic-equipped trucks prior to ’06 require BD’s programmable Tow Loc and Pressure Loc kits to electronically control torque converter clutch engagement
  • Transmission line pressure just 83 psi during descent

Jacobs Brake
  • Insufficient braking power: had to use foot brake during descents in Drive
  • Doesn’t operate in 1st gear
  • More restrictive when open; hurts performance
  • Transmission line pressure just 82 psi during descent
  • Slow reaction time

PacBrake
  • On/Off brake activity while in cruise condition results in noisy release of air pressure
  • Insufficient braking power: had to use foot brake during descents in Drive
  • Slow reaction time
  • Doesn’t operate in 1st gear
  • Most restrictive of all brakes when open; hurts performance
  • Exhaust pressure regulation requires multiple moving parts that could stick or fail
  • Transmission line pressure just 83 psi during descent

Banks Brake is superior to BD, Jacobs and PacBrake when measured at 7% downhill grade in 2nd gear

Banks Brake, tested on Superflow SF-1020 flowbench with valve in open position, had superior airflow over PacBrake, BD and Jacobs

Banks Brake achieved 203 peak braking horsepower, topping PacBrake, BD and Jacobs

Banks Brake delivers instant braking power; PacBrake, BD and Jacobs need more than 6 truck lengths longer than Banks Brake to achieve the same level of power Flow restriction

Worth the money spent

Believe it or not, I finally got the brake installed. Between holidays, snowstorm, and floods, things have been real crazy in this neck of the woods. Thought I would take a few moments to commend your people on a very well done piece of work.  Everything fit perfectly, it works as well as you said it would, the directions were easy to follow and the pictures were well done. Thank you for a product that is worth the money spent.  -Richard G., Kalama, Washington

RV Magazine reviews the Banks Brake

But it was this simple Banks Brake kit that positively changed the way the truck handled with a trailer. Truck owner and RV Magazine contributor Tony Becker said that he wished he had done the upgrade sooner. He saw the benefits of the Banks Brake immediately.

The idea that you can cut your downhill speed without using the wheel brakes means that they will be fully functional when you need them most. Less wear and tear means less money spent on buying replacement parts. As you already know, heavy loads and steep descents with a trailer in tow mean that you are tempting fate with just the stock braking system. The last thing you want is to smell your brakes burning up as the rotors or drums turn red-hot. More pedal force just increases the problem. Read the full article!


Banks Brake on TrucksTV

As part of an episode on the Banks PowerPack, TrucksTV host Stacy David touches on some key points of the Banks Brake (the Power Stroke model is shown here).
