No, this has nothing to do with hungry yellow circles gobbling up dots while being chased by ghosts. However, gobbling up miles with your diesel-powered truck and trailer combination can do a number on your braking system, especially if you’re headed downhill. To help save your tow vehicle’s brakes, Pacbrake announces the release of the ISC exhaust brake for the model-year 2004 Cummins engine. Pacbrake exhaust brakes work by generating backpressure, which slows down the vehicle prior to use of the service brakes, according to the company. Each unit comes factory preset to the engine manufacturer’s maximum allowable exhaust backpressure limit.
