Caliper piston will not go back in?
I have seperated the caliper from pressure line. I drained the oil from caliper. Still, the piston will not go back inside. The problem i had was, vibration at high speeds and brake drum was heating up. Wheel will not rotate easily when lifted up. What is wrong with caliper?
The camry front caliper, when i closely examined is not screw type. But it needed some presure to push it back. I used a breaker bar. Placed it along the piston face and pressed it down gently. It went back. But what concerns me is, when it needs so much pressure to push it back, how in normal operation will retract when brake pedal released?

As kelly_f says, it sounds like a screw-in caliper. They are most often used on rear wheels so a parking brake can be fitted but they are appearing everywhere, identifiable by the X on the piston surface. I have screwed those back in (clockwise) with a screwdriver from the side and colorful language. No amount of pressure will force them back in.

You need a c clamp to press the caliber back and dont need to disconnect it. Now you need to bleed the brake system.

possible screw in type you see notches in piston it is screw type can rent a tool at most parts stores or twist it with plairs possible but takes forever most likely reason for it not to go back in that or its bad buy a new one
