A âJake Brakeâ is an engine compression release brake used especially for steep hill downgrades. The Jake Brake opens the exhaust valves when the piston is near top dead center (where ignition normally occurs). On the upstroke, the piston compresses the air in the cylinder to 1/15th its original volume, which creates drag on the engine. The Jacobs Engine Brake then releases the compressed air and the energy stored in it before it can push back on the piston during the down stroke. The Jake Brake turns a power producing engine into a power absorbing air compressor and in turn, causes the truck to slow down.
