If your vehicle is equipped with an auxiliary brake, follow the instructions provided in the auxiliary brake owner's manual. Failure to follow the instructions during wet or slippery conditions could reduce vehicle control and result in personal injury or death.
Auxiliary brakes should not be used as a primary or service brake. The vehicle's service brake must be used in order to bring the vehicle to a complete stop.
Certain auxiliary engine braking devices are approved for use on these engines. Refer to the Truck Engine Application and Installation Guide or see your Caterpillar dealer for more information. For information on the specific auxiliary engine brakes on your vehicle, refer to the information that is provided by the OEM of the vehicle.The anti-lock brake system (ABS) of this vehicle may interrupt the operation of the auxiliary engine brake during the actuation of the ABS. Compression brakes and exhaust brakes are typical examples of auxiliary engine brakes. For information on the operation of the ABS, refer to the literature that is provided by the OEM of the vehicle.The exhaust brake provides additional braking in order to slow the vehicle on grades and curves. The exhaust brake also helps to control the speed. The exhaust brake is useful when a reduction of speed is necessary, but a long application of the service brake is not desired. Controlling the slowing or downhill speed of a vehicle by using the exhaust brake results in reduced wear on brake linings and brake drums. A reduced wear on these components helps to save the service brakes for emergency stopping requirements.An exhaust brake generates the maximum retarding effect at the engine's maximum rated rpm. As the engine rpm decreases, the performance of the exhaust brake also decreases. For maximum available retarding, the operator should select a gear which will provide the desired road speed at the highest allowable engine rpm.On long downhill grades, an operator should establish a “control speed”. The “control speed” is present when the force that pushes the vehicle is equal to the retarding that slows the vehicle. The “control speed” is established with little use or no use of the service brake.To maximize the benefit of the exhaust brake, the exhaust brake should be used when the operator wants to slow the vehicle. The exhaust brake should be kept in the
