I have some calipers removed from my Honda that were replaced with rebuilt pieces. I want to save/store the removed calipers as "spares". Since the had brake fluid in them and it is really hydroscopic (sp?), I am concerned about moisture in the piston/cylinder bore causing rust and making them unusable.

Any suggestions on the best way to store these, short of disassembly. I have sprayed brake cleaner into the calipers to remove the bulk of the brake fluid but am not sure if that is sufficient.

Thanks,
Rory
