How to Remove Calipers

I followed the Polaris manual to replace my three brake pad sets.

Per the manual I "loosen the pad adjuster screw, then, remove caliper from mounting bracket."

I’ve worked on motorcycle brakes for a long time, but can’t figure how to go about removing the caliper. The manual’s a little light on details.

I’m sure there’s a particular trick that once known…but I can’t figure it out and don’t want to butcher anything in the process of learning. (FYI, H-D manual’s give step-by-step through each procedure.)

Appreciate any help.
