Well on my front brake, only one piston move, the other move but slightly, and make the rotor drags. I apply the disk on a very step downhill and for long time the pads on the metal side became orange with the temperature that was achieved.
Does it have solution ????
Thanks.

Could be a few issues. One is an improper bleed. An air bubble can inhibit piston movement. Two is sticky piston. Force the sticky piston out some more, clean, and lube. You can use mineral oil, silicone spray, or caliper grease to lube the piston. Then work it in and out until it moves freely. It also sounds like the brake was not centered correctly. If you have the direct IS mount, you may need to use shims to move the caliper around.

You will always have one dominant piston.

If you have no idea what I'm talking about, bring it to a shop.
