undo the clevis pin holding the rods that go in the master, take the lid off the reservoir and try pushing in on each piston with a rod by hand. if they don't move at all, they're locked in place. they should move with some resistance and return smoothly. on the rear e-brake setup, the bolt sticking out sets how far the caliper's pad is pushed out of the bore at the start of the stroke. loosen the nut, back the bolt out a few turns , apply the brakes and see if any space appears between the pads and rotor. piston may be stuck in the bore. very common. turning the bolt in will push the piston more to the caliper, allows for the e-brake to be adjusted for pad wear if it loses it's clamping ability. Neither of these "inspections" will require you to undo the brake lines, so no worry yet about getting air in the lines.
