Jim,
Dave Lenzi's new middle wheel disk system includes a hydraulic lock system that works.
A brake lever applies pressure to HEAVY spring which in turn presses on a hydraulic cylinder which applies pressure to a modified VW
front disk caliper.
As the brake system cools down the spring maintains pressure in cylinder and on the caliper.
Hopefully he'll bring it to Tucson so you can check it out.

I work on these coaches all the time. If an owner wants his parking brake
to work, then it gets Albert B's kit. Then they work marginally well, as a
parking brake. Emergency brake? Not so much. But you absolutely MUST
EXERCIZE the cables. Sitting a long time with the parking brake set will
almost guarantee dragging brakes. I have read the D.O.T. mandate on
emergency/parking brakes. They must be a whole separate system, applied by
hand or foot. A line lock hydraulic system is not approved. So, I don't
install them. Wheel chocks work quite well. Owners can do to their own
coaches whatever they choose and feel confident with. Me, I don't want the
liability.
