If they're not warped or scored, you can just put a set of pads on and
be done with it. If the surface is "rippled" (kinda like growth rings
on a tree) it *MAY* need to be resurfaced or replaced.
If it is necessary to resurface 'em, they'll need to be removed and
taken to a shop with a brake lathe and turned. The shop will measure
the thickness with a micrometer and then check for any warpage with a
dial indicator. If they can'[t be turned without exceeding the
manufacturer's MINIMUM thickness, you'll need to replace 'em. If they
can, the shop will put 'em on the lathe and turn 'em. Takes about an
hour (at most) to do a pair.
If you don't need to resurface them, hit 'em with some 220 grit
sandpaper to scuff 'em up a bit and break the glazing. (Take the
shine off of 'em) That'll help the new pads set well.
Really not a difficult job to replace pads.. Pretty much if you can
turn a wrench, you can do 'em.
