Diesel Pusher Exhaust Brake


Does the exhaust brake on your diesel pusher normally lose power/shut down based on a minimum speed or rpm?

Just wondering - my dodge truck E-brake turns off at about 28 mph - no matter the gear or rpm.

My works until my rig is almost stopped, I can pop it on the slow the rig down as I'm coming to a stop sign to slow the rig down to save my brakes. Mine is a PacBrake so may be different on newer rigs.

I agree with Wild Card. We have had an exhaust brake on 4 Motorhomes. All of our exhaust brakes let go when the "solid gear" drops out which for us is 2nd gear, and which occurs around 10-15 mph.
