Another possibility for the cylinders leaking after only 2.5 years is abrasive grit in the system. You don't necessarily have to replace the cylinders, assuming the bores are in good shape which they certainly should be after only that short time, you could hone the bores and just install new cups available as wheel cylinder kits but before I did that, or replaced them, I'd very thoroughly flush the entire system. I've use simple rubbing alcohol (isopropyl alcohol) for system flushing, followed by a long blast with dry air to insure complete evaporation of the alcohol. Then just to be sure, one flush with fresh brake fluid.
