rebuilding brake calipers for storage

Hi all,

car info:
year: 2004
make: Dodge
Model: Stratus
Trim: Sedan, SE, J vin

I recently replaced my front brake calipers with reman’d units, because the dust boot was torn on both sides and they were starting to stick. I replaced rotors, pads, calipers and soft lines on both sides (the calipers and hoses were original to the car). The core charge on the new calipers was only $20 per side, so I decided to buy two seal kits, replacement pistons, and hardware (slide pins, rubber bits, etc) for around $15 per caliper.

I have a factory service manual, so I have a vehicle-specific guide for rebuilding these calipers, but since I plan on storing them, in case my calipers need replacing again in the future, is there anything I should do differently to rebuild them for “storage” and not for immediate use? Or should I hold off on rebuilding these calipers until I’m ready to use them?

Thank you!
