RallySnake,
What happens if you pull the brake pedal all the way up by hand a few times and then apply the brakes? Do you still have no rear brakes? If so, it sounds like it's time to pull the rear calipers and sneak a peak

. Are you sure the pads aren't hitting part of the mounting brackets preventing full piston travel??
Greg, you said it--I need a weekend too! How's the final assembly on your beast coming along?
