I have the Roadmaster Brakemaster which connects into the coach air brake system. Through two coaches and two cars it has given me no problems. I did have to design and install a simple pair of rollers for the lower end of the cylinder so that end was loose rather than secured to a post in the floor in order that it would retract/collapse enough to turn the brake lights off under normal driving conditions.

I'm a happy camper.
