GM metric rear calipers w/e-brake

I have the GM metric rear calipers with the e-brake on my 9 inch Ford in the Willys. How do the e brake arms adjust. ?? Do you just rotate the arms and they screw out an adjusting nut on the inside.?? I can't seem to get them to grab hard enough to hold the car. I have the full Lokar floor mount e-brake system. Also they dragged quit a bit at first. Now they have loosened up a bit but still drag a little.

I used those same rear disc brake calipers on my previous ride. They are difficult to adjust for the initial adjustment, but once that is completed they work well. See instructions below.

I also used the Lokar floor mounted emergency (parking) brake handle. I found that it doesn't have enough mechanical advantage to apply the pressure required against the discs. I made a lever to double the mechanical advantage. See sketch below. It is installed under the car between the Lokar emergency cable block and the emergency brake handle. This solved that problem.

Thanks for the quick reply. Just what I needed. Looks like an all afternoon job just attempting to adjust them. Then another afternoon modifying and remounting the brake handle. Guess that's what hotrodding is about. Wouldn't be any fun if things just bolted together and they worked as planned. haha
