Q: Drive Side Caliber Freezing Or Sticking

The flexible rubber hose supplying the caliper could be collapsed internally and acting as a check valve. If the sliding pins in the torque plate were not replaced or removed and serviced, that could be a cause as well. The other possibility is a stuck proportioning valve. If only one caliper is stuck, it is probably not the master cylinder. If two wheel cylinders are stuck (they might be diagonal cylinders because the brake circuit is sectionalized for safety) are stuck, it could be the master cylinder.
