Disc brakes-storage issue?

Yes, the battery maintainer will do just fine.

It's also a good ideal to put some silicone grease on the weatherstripping every year before storage. Just got mine prepped today for storage so that reminded me. It makes your seals last longer and prevents them from drying out. Here's a link to some.

Adam...I didn't think about the weatherstripping. Thanks.
I wonder if I'm missing anything else.

This is a very good tip and one that most of us forget!

"Do not apply the Handbrake or put the Car in Gear. Linkages and Handbrake Mechanisms can seize over a storage period and it's better they freeze unactivated if they do. This is because you'll have the Mechanical Advantage of the Handbrake Lever and Shifter to free them if they seize. Apply them, and you may have to disassmble the entire assembly to loosen it"
