[TR] Jake Brake: was 'free wheeling'

[terryrs at comcast.net]

Flip side of free wheeling.B  My uncles and father in the logging business
used something they called a "jake brake" to slow them on steep grades coming
out of the mountains with a load of logs.B  I kinda understood this as
shutting down the valves in a diesel engine, so that engine compression did
the work of brakes, so even the water-cooled brakes on a truck would not
overheat.



This close to being right?



Obligatory TR content:B  Who could live without TR valve clatter????
