they make a tool for it that you should be able to buy at any parts store, i was able to use a pair of needle-nose pliers, open the pliers and put the tips into the notches on the inside of the caliper piston, turning clockwise will compress the piston.
NO! Brake Calipers are what compress your Brake Pads on to the rotor which turn simeultaniously with your wheels.
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.
the piston on the rear calipers will turn in a clockwise motion and that is how they retract.
If they are the same as a 97 Maxima then you twist them, don't compress them. To compress the piston you do it with a 'Disk Brake Piston Tool'. You can get this at Pep Boys for $12. To compress the piston on the passenger side you turn the piston clockwise. To compress the piston on the driver side you turn the piston counter-clockwise. Be careful trying to turn the piston using pliers or some other tool as you may tear the rubber seal around the piston.
are u trying to change them?
The rear brake calipers screw back in. This is because of the park brake. There is a tool that you can either buy or rent from one of the larger parts stores.
The easiest way is with a "C" clamp.
Have you replaced your rear pads or calipers? May have air in the lines. The reason the E- brake works is because it is engaged by a cable and has nothing to do with the hydraulics of your brake system.
The calipers on a Mazda 6 turn inwards you don't push them to compress them.

You can purchase a disc brake tool for compressing the calipers at any auto parts dealer for about $8.00. You will also need to have the brake fluid filler cap off.

If the parking brake is connected to these calipers a special tool is required (not expensive) because piston is threaded. Tool available at Sears or auto parts store
