There are three kinds of engine operated brakes.  Jake is built into the valve system in the engine.  Very powerfull and very noisy. Then there is the exhaust brake - one is called a Jake also and the other is a Pac system.  They are butterfly vavles that close against the exhaust outflow putting a back pressure on the engine.  The third is a retarder and is installed in the Allison Transmission.  Very good but take a large radiator to disapate the heat. 

The exhaust brake CAN  be left on all the time but then when coasting it comes on a you lose "downhill momentem."  If in heavy traffic or where there are lots of stop lights - to me it is better to leave it on and just play the throttle to engage it or keep it open.
