Time for a maintenance

[Golddeenoh]

if you take the rotors off, mark their position in relations to the hub as to be sure they go back on the way they came off and prevent any possible issues with the mating surfaces.

Resurfacing the rotors depends on the condition, given that you went 106k on them probably means that they could use some fleshing up as long as they are not too wore down to be resurfaced. if the rotors are have waves or rings on them, then resurface.

As long as you don't open a line in the brake system, you should be fine, the fluid in the caliper will go back into the system when you press the piston back into it.

If after you drive the brakes pulsate and you didn't resurface the rotors then the rotors need to be put on the brake lathe and corrected for wobble.
