remove the pads from the calipers, crack bleeder screws, gently depress pistons, reinstall pads, put the calipers back on the bike/rotors and bleed the system.

If the caliper pistons aren't binding they should push back easy enough. Find something flat to slide between the pads. Make sure it's clean. Put a flat blade screwdriver between the pad and piston and gentle turn/lever the piston back. Do not lever on the friction material, it will damage the surface of the pad. Do this on all pistons and both sides. They only need to go back a bit not all the way. If you've got two four pot calipers, as most modern bikes do, it can be a bit of a juggling act as some pistons will move out as you push others in. As long as the pads are still in the calipers you should be safe from them coming all the way out. Refit your wheel and remember to pump up the lever when you've finished.:old-cool
