I believe one of the big three is using a form of "jake brake" now on their
1 ton deisels. With such heavy loads and just not enough rubber on the
ground to stop it, they will have to find new ways to stop burning up the
brakes.

Harvey,
The exhaust brake is turned on or off by the driver by means of a
switch. When the brake is on however, it is not activated until you take
your foot off of the gas pedal. At that time, the engine exhaust is
blocked, which causes the engine to act as a brake. This works well when
descending hills, or in heavy traffic, when you might prefer your truck and
rig to slow down when you take your foot off of the gas pedal. It did not
work well when I took my foot off so as to roll through the standing water.
When the exhaust brake is not turned on, the diesel engine tends to
freewheel, rather than retard the vehicle as does a gasoline engine.

Tom,
I am not familiar with BD exhaust brakes but plan to install an exhaust
brake when I purchase a new diesel puller in the near future. Reading your
post I am confused by the comment, "I was travelling with the brakes on"
then goes on to describe your near disaster experience. The way you
described the event seems to say that application of the BD exhaust brake
was not a direct result of driver action.
Is the BD exhaust brake applied other than on demand by the driver?
