Prior to bleeding, tighten ALL of the shoes (2 adjusting wheels per wheel on Huck brakes) so that you can't turn the drums by hand. (You will loosen them to specs after you are done bleeding.
Make sure that you back off the parking brake cables completely.
With Huck brakes, loose shoes will cause too much wheel cylinder piston movement preventing the shoes from seating with the drums. You will run out of piston stroke in the master cylinder before the brakes will work. Multiply this X 4 and you got no brakes.
Bleed the brakes.
Adjust the shoes to specs.
Stop on a dime.
+ 3 on This ^^^^^^^^^^^^^^. Plus if this is the problem.........pump ( a lot) the brakes with the brake master cylinder cap off. Watch the fluid flow back into the master after you stop pumping. As all that fluid moving the shoes out returns to the master it’s a lot back flow.
