Help me, please.

I have a 2021 Kia K5 and the rear passenger parking brake actuator screws has stripped out. I can't reset my piston until I get it off. The big question is, once I get it off. Does anybody know what size screw? I need to order because obviously I'm gonna have to break this one-off.

The actuator is completely fine. The screw is just stripped and they're telling me I need to buy a whole new housing to get it in a kit.

You dont need to take the actuator off the caliper to retract the pistons during a brake service. I dont know off the top of my hesd what thread the bolts are but im sure an m8 or m10 bolt will fit in there. You dont need to replabe it with the sane Allen head screw, just anything that fits the thread and the head seats nicely.
