Push the bolt completely out of the caliper and clean it well, then put some special lube the have in a little tear open pack and coat the sliding parts. I used to use never seize but was told this stuff is silicon based and won't swell up the rubber like never-seize might.
You probably did not lubricate the calipers when you changed them and they are sticking. Or its entirely possible that the rotors are too thin. Always clean and lubricate the brake assembly before reassembly.
You probably have a warped brake rotor. New rotors are fairly inexpensive, I would replace both front rotors and brake pads while your in there. The calipers and sliders along with the brake hoses and lines need to be examined also.
F1 brake calipers are made of aluminium.Here is quotation from the Technical rules:11.2 Brake calipers:11.2.1 All brake calipers must be made from aluminium materials with a modulus of elasticity no greater than 80Gpa.
NO! Brake Calipers are what compress your Brake Pads on to the rotor which turn simeultaniously with your wheels.
Brake calipers are the hydraulic devices that wrap around the rotors and pinch the brake pads into the rotors when you stop.
Brake calipers are what house the brake pads and fit over the rotor. If you are working on the brakes, usually the calipers need to be taken off in order to work.
Calipers frozen? Calipers frozen?
front or rear? both are very similar. take the wheels off. loosen and take off the calipers (should be 2 bolts if my memory serves me correctly, the bolts are kinda long. slide the caliper off revealing the brake pads. replace the brake pads and put it all back together. Don't forget to use brake lube on the sliders of the calipers.
Lift the vehicle on a car jack, remove the tire, remove the brake shoe/calipers, and remove the old brake pads. Put in the new brake pads, replace the brake shoe/calipers, replace the calipers, and lower the car.
You can buy a kit to rebuild the calipers. It is simpler and easier to buy rebuilt calipers.
Brake calipers are what squeeze the brake pads against the brake rotor.
No need to rotate the front caliper pistons as you compress the front calipers. That process is only for the rear calipers because of the parking brake mechanism.
