Look at the slack adjuster. On top will be a square post, about 1/4” if IIRC. On the side will be a little pin that you have to pull out to back the slack adjuster off. Otherwise it will only turn one way.

I use a pick with hook end to slip under the release pin, so I have both hands free.

If you have the Meritor pads, they will seem impossible to install. It will appear the ears are just too wide to slip into the caliper. That’s when the A Ha hit me. A close exam of the ears on the pad showed them to be tapered, and the caliper is tapered in the area where the ears ride. Start with the thick one, push it down into the caliper where the cutout well is located. While holding it down into the caliper, slide it sideways. The purpose of that taper is to keep the pad in place. The non OEM pads I bought were lacking that slight detail.
