Default Rear brakes started locking

Hello,
I have a 2004 Softail. Suddenly my rear brakes started locking up when they haven't even been used. After I sit for several minutes they release. Then the process starts all over again.
I had the break lines changed after this started, still does it. Could it be the caliper or master cylinder?

The caliper needs maintenance , the pistons are jamming.
More than likely .

Even though it happens when the brakes haven't been touched? Caliper was my guess, but I've been reading about the master cylinder

Take a wrench for the bleed port with you, when the rear locks up again break the bleeder port a hair. You get a good spurt there's air in the system, probably sucking at the MC. Just a little wet it's caliper issues pads expanding as it get hot, could be dirt, bad pads or an alignment issue.
