Driveline Braking

On-Highway Trucks

DRIVELINE BRAKING Driveline Braking is used to augment the main service brake system. A technology called Engine Compression Braking allows the engine to remove horsepower from the driveline by compressing air. In addition to provid- ing additional stopping power, driveline braking also reduces maintenance costs by prolonging the life of brake linings. This technology is often referred to in the industry as a “Jake Brake.” NOTE: Engine Compression Braking is recommended for all CT660 driveline braking applications.

Driver Selectable Engine Compression Brake Levels NOTE: The driver can select levels 1-3 at anytime with a 3 way toggle switch, even during braking. An alternate Driveline Braking option is a Transmis- sion Retarder. This is an option within the Cat CX31 automatic Transmission. It cannot be used in conjunc- tion with Engine Compression Braking because of driveline overload.
