Brake Caliper Rebuild?

I have an 09’ with around 20k miles on her. Going through the maintenance intervals made me realize that replacements of o-rings in calipers and master cylinders is suggested on a 4 year interval. Our Michigan weather has been garbage lately and I am considering getting rebuild kits from Murph’s. Always good to ensure critical systems are in top condition. Has anyone tackled this task? Hints?
 
mine is a 2013 just replaced the pads and fluids. a mechanic on youtube suggested to always take the caliper out and clean rear brake is working amazingly better than before and the old pads still had plenty left but put new ones on since I bought them. i was wondering if cleaning the caliper made a difference and may be weren't working properly before .... I might have to do the same so since I haven't done that job be interested as well

I have a bit of reservation in the “if it ain’t broke, don’t fix it” department. Nearly all the obvious rubber components have been replaced in the last year or so (brake lines to stainless, new coolant hoses, new diaphragms for fluid reservoirs,…). Going the extra mile for calipers and masters seems to make sense.
 
I get that but at the same time I don't want to wait until it brakes and that usually happens at the worst time :) wondering how much of a job that is ..
 
Any time I need new pads I rebuild the caliper. The pistons don't have protective covers and get dirt and gunk on them. If you don't / can't clean them well enough before you push them back into the caliper they will stick. On the C-10 and I assume the C-14 also the only thing that pulls the pads off the disc is that the seals have flexed when the brakes are applied and they pull the pistons back. As the pads wear the seals flex then slide to a new position.

If you make the mistake I did and push the dirty pistons into the calipers I was unable to turn the wheel after the new pads seated to the disc. I also had to reconnect the caliper to the he line and use the hydraulics to push the pistons out. Compress air wouldn't do it.
