Dot 4 fluid will be fine, but won't function nearly as well as 5.1 because it has a lower boiling point, meaning it cannot handle the higher temperatures that come with downhill riding. Whatever you do though DO NOT USE DOT 5 FLUID! The previous owner of my brakes had them shop bled and the mechanic used dot 5. The o-rings are now coming apart, and chunks of them are flushed out when I bleed them. This is at least what I got from my talk with those guys yesterday.
