Need to move 4905 with no motor. Found a leak in front tank and need a work around. Could I plumb air straight to the input side of park brake by driver just to release brakes?
Plug your lines in the rear, air some shop air or portable air compressor then move. ;)
Van, yeah, thats how I would do it but there is a leak in the front air tank. I ended up feeding the supply directly into the output of the park release.
