To adjust the caliper you ratchet the arm back and forth until you only have 1/4" --1/2" travel. Before the lines are connected.

In the photo below, the groove at my thumb is where the ebrake seal rides.

Ahh, thankyou very much! These calipers have a some quirks, but once figured out=cake!
The calipers look pretty simple-compared to some parts-like an auto trans or whatever.
Keep up the good work F-250 restorer

I'm not sure I needed to become an expert on these calipers. I guess the most valuable lesson here is that a person doesn't have to search high and low for the 76--78 el dorado calipers. Anyone can pull the big GM calipers from a seville or fleetwood, and swap out the pistons if you need to. That is good to know since the dodo calipers are getting extremely hard to find.

I guess it was good to learn all that I was forced to learn before I installed them incorrectly. I'm sure that had I done that, I would have thought them crap like everyone else who installs them wrong.

If this post helps others, then it is worthwhile.

I found that TSM makes a tubular bracket which should adapt the oem ebrake cables to these calipers.

Since I'm banned from the local pick-your-parts for taking a hammer and pry bar to their water machine (selling ice, not water on a flaming hot day and refusing to refund my $) it's a bit more diff. to snoop for parts.

Ebay brackets

I bought the caliper brackets on ebay from Great .... 4X4. They look like he just cut them with a shaking lazor, drilled and tapped the holes, and shipped. No grinding of sharp edges, no paint. They look like 'high school shop' time.
