You can take the pads out and then apply the brakes to push the pucks out, but be careful as they can fall right out and then need to rebuild the caliper and bleed entire system. What I do is apply the brakes just enough to move the pucks out far enough to see that they have moved out beyond their normal position, then apply some brake clean and scrub down the pistons(pucks) then when you are all done, push them all the way back in and give the whole thing a good spray and scrub. Now when you re-install the pads, MAKE SURE YOU APPLY THE FRONT BRAKE UNTIL YOU HAVE PRESSURE. before you move the bike. Very important.
Now if you feel you need to lube the pistons only use a bit of brake fluid to just help push them back in.

I do have a small hand pump vacuum that makes it easier if you'd like to wait 'til the weekend?
