Exhaust Brakes

Jacobs Exhaust Brake® provides additional vehicle braking power by restricting the flow of exhaust gases and increasing backpressure to the engine.  The exhaust brake can be used alone or in conjunction with other Jacobs® braking technologies.

How Jacobs Exhaust Brake Works

By increasing backpressure to the engine, the exhaust brake forces the pistons to push against additional force during the exhaust stroke, slowing the crankshaft’s rotation and helping to control the vehicle speed. Overall, this requires less use of the service brakes, giving them a longer life and reducing the overall cost of ownership.
