What you guys are talking about is known as a Microlock and was very
popular in the sixties and seventies. Whether it was electrical or a lever
you moved they both operated the same was. To set brake flip lever all the
way or push and hold the button then step on the brake HARD a couple of
good stomps but not all your weight to set brake. The system was for short
term stops not overnight parking brakes. To release the brake simply flip
the lever all the way to the "Drive" position and the brakes are released
that easy. The electrical version you simply stomp on the brake pedal
without pushing the button and it opened the one way valve and off you go.
The only safety consideration is with the manual lever control THE LEVER
MUST POINT TO THE FLOOR WHEN THE BRAKES ARE RELEASED. This way the
vibration from the truck won't close the manual valve if mounted the wrong
way.
