How do I change my disc-brake pads? How do I avoid letting the fluid out?

It would be very helpful if you told us the make and model of your brakes. – Jack M. Aug 26 '10 at 13:21
oops, hard to write 'brake' as a computer programmer who writes 'break' all the time :) – Johan Dahlin Aug 26 '10 at 15:47
One other thing to be cautious with is to NOT depress your brake lever while the pads are out, as this will cause the pistons to extend out to each other and not leave any room for installation of new pads. (and possibly come out altogether depending on brake brands). If your pistons do extend out you can start sliding in playing cards to push them back into their ports, then when you get some room, you can use a tool to finish pushing them in. – M.

Not to nit-pick, but it should be spelled 'disc' rather than 'disk'. – Dustin Aug 26 '10 at 20:18

Generally speaking you should just be able to take off your wheel and grab them with some needle nose pliers. I just grab onto the tab (see picture) and slowly ease them out. Mine are just held in with magnets. More info is probably needed for a better answer.
