Exuast Brake ?

[Archive]

Can anyone explain the difference between a Exuast Brake and A Engin Brake? How does it exactly work?

An exhaust brake closes a baffle in the exhaust pipe. This builds backpressure which helps to slow the truck down. An engine brake is a mechanical device which closes the exhaust valves and uses cylinder compression to help slow the truck. Someone else may know more. I hope Im somewhat correct about this.
