Peak Braking Definition?
Does anyone know what is meant by "Peak Braking" in relation to a cummins engine. My VmsPc shows a PID for Peak Braking.
I am searching for a method to know if my exhaust brake is working properly. I thought of installing a micro switch that would be actuated by the exhaust brake air cylinder piston shaft and temporarily connecting the switch to an LED to show if the piston was actuating. However, that is proving to be difficult due to problems in mounting the switch.
I was thinking that "peak braking" might be associated in some way with the operation of the exhaust brake, or show some indication of exhaust braking.
My transmission shifts down to 4th gear when the exhaust brake is activated so it is difficult to determine if the reduction in speed is the downshift or due to exhaust back pressure. To test this, while descending a grade, I have manually shifted down to 4th and then actuated the exhaust brake, but it is hard to tell if the exhaust brake is slowing the coach since there really isn't a drastic reduction in speed, as I would expect.
Hence, trying to find another method of testing.
