Storage

I have a 71 bus that I need to store while I am at collage. What do I need to do (other that a can of fuel stabilizer) to make sure it stays in good condition? I will be able to drive it periodically when I am home. The engine needs to be rebuilt, so I am not too worried about it, but I recently put in new calipers and wheel cylinders. Will sitting around ruin them? Thanks for your help! Bryan
