Saab 9-3, intermittently sticking rear caliper

Saab 9-3 SS 2006 MT, intermittently sticking rear passenger side caliper.

Hi. I’ve been trying nearly a month to figure out what is happening with my rear caliper. It started with a sticking handbrake puller on the caliper. I took the car to a garage a had the caliper rebuilt. Sticking handbrake after this transformed into intermittently sticking caliper. It didn’t let the wheel to spin freely after i released the brakes. It didn’t cause any overheating or smoke.
Then I put in a brand new OEM caliper and new hoses and new rotors AND it changed nothing. Then the ABS unit was replaced with a used one. And for a week everything was ok. But now the same thing happens. The rear right wheel is braking without my help but doesn’t overheat. Also when i release pressure by opening the bleeder screw it frees the wheel. Also if i apply brakes really hard the caliper will not stick, and only if i apply them gently (like you do when you usually drive) it will stick.
Really looking forward for any advice. Thank you.

You have have an issue with the parking brake on that side of the car. If the parking brake is built into the caliper you may have a cable issue.

I tried and disconnected the cable alltogether. Nothing changes
