MSP Rear brake install problem!

[AllthingsJDM]

I got all new rotors and pads all the way around. I did the front no problem, and just started the rear, i got the pads in on the left side but i cant get the caliper piston in so i can fit the pads over the rotor. I tried to use a c clamp to push the piston in like i did the front put in wont budge. I dont want to put to much pressure on it for something to brake. Usually with the c clamp the pistons go in with ease ( like the front ). Help guys im in a pickle!

I think the msp brakes turn in. Using a c clamp with screw it up
