There is a cool Youtube channel, called Lock Picking Lawyer, where dude tears apart, picks, and details the flaws of many locks in quick videos, mostly under 5 min. A lock earning his respect is fairly rare. Once you watch a few vids there, you will never buy anything Master Lock branded again. If you are concerned about any item rolling away, he recommends this lock, along with this chain. His channel is a great resource for any kind of lock you are considering, even things like elec front door ones. That hardware linked above will definitely take longer to overcome than loosening a brake line fitting on a brake-locked SxS, without concern of failing hydraulic seals.
