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.
