Bleeding brakes first time question

Getting ready to do annual wheel circuit bleeding. Thanks to tech article I understand procedure. Speed bleeders coming in the mail. Just one question though. I don't need pads front or rear. Must I still remove calipers and shim pads to get the pistons all the way back in? I understand that this will push the old fluid back up into the reservoir to draw off. But, won't a little more bleeding, w/o shimming do the same thing. Thinking, pushing old fluid up into reservoir to remove or just more bleeding at the screw will accomplish the same. Am I making sense?

Altough I like removing the calipers, that is so I can tip them upside down and really evacuate all the crap that may be sitting on the bottom. Bleeder is at the top so doing it in place does not really do it for me. But that is me who found too much crap at the bottom of calipers that did not get out with bleeds on cars & trucks, so I don't take a chance with the bikes. Not that I ever found anything untoward in the bike, but you never know.

However I only do that every couple years, yearly just a regular bleed without shimming. I can see the point of shimming if the pads are worn, mine never really are when I do that.

Pushing the pistons out and a good inspection/cleaning, never hurts and if there is any dirt stuck to them you won't be pushing it toward the seals when you replace the pads and cause binding. Too many seem to have binding problems after pad replacements.

Roger that. On other bikes, when replacing pads, good inspection of calipers and cleaning pistons was what I have done. Thanks.
