Product Details

Its computerized brake control (CBC) module automatically senses throttle position, controls brake engagement and cuts out annoying brake noises. The fast warm-up function prolongs brake durability. Automated brake disengagement at low speed smoothes stop-and-go driving. The pressure actuator is coated with a high-tech material to withstand the harshest environment. Built for years of trouble-free service, Banks Brake never needs adjustment.

Before we go any further, we should mention that an exhaust brake is not a noisy compression brake, or "Jake" brake such as used on diesel big rigs and dump trucks. A Jake brake works by using hydraulic pressure to momentarily open the exhaust valve at the end of the compression stroke, venting off the compressed air into the exhaust system.

An exhaust brake is a device that essentially creates a major restriction in the exhaust system, and creates substantial exhaust backpressure to retard engine speed and offer some supplemental braking. In most cases, an exhaust brake is so effective that it can slow a heavily-loaded vehicle on a downgrade without ever applying the vehicle’s service brakes.

An exhaust brake, when closed, stalls the turbine section of the turbocharger. The exhaust brake must open before the turbo can spool up again to provide boost on demand. The Banks Brake is engineered to open at speeds below 15 MPH, when very little exhaust braking is available anyway, to quicken turbo response when the driver again steps on the fuel pedal. Only the Banks Brake has this computerized feature. This is just one of the functions of the CBC (computerized brake controller). And just as noted above, any restriction in the exhaust system downstream from the turbocharger will negatively affect the turbo’s ability to generate boost under normal driving conditions, and especially at full throttle. Here too, the Banks Brake, which is designed to actually enhance exhaust flow out of the turbine in the open position, improves both power and fuel economy, as well as supplemental braking when needed.
