Bens right, but i think its clockwise? lol dont even remember. If you have some brake grease or general lube ( preferable not a spray as they dry quicker ), apply a light amount on the outer edge of the piston so that it doesnt catch on the rubber seal. Then when done if the brake fluid has overflowed make sure you put the cap on and pump the brakes for abit to push the pistons back out to their ready position. Then remove any excess fluid to bring it to the max line. Also remember to wash off any excessive brake fluid with water as the brake fluid will eat the paint if left there too long.
