If it's not releasing it may be the caliper but more than likely it's the brake line collapsing.

Can you tell me what to look for in way of a collapsing brake line. Is this something you can observe without removing it?

Definitely check the slide pins first. It's very common for them to seize in their bores, particularly the lower ones. Is the inner pad worn more on one end than the other?

Ah, too late for that, no pad left in the inter side.

pump the brakes and then see if that side is applied / stuck. open the bleeder momentarily and see if it releases. If it does then fluid was trapped.
