Dot 4 or Dot 5 Brake Fliud?

i've occasionally had instances where dot 5 will find the absolute teeny-tiniest microscopic places to weep where 3 or 4 won't. but other than that, i like 5 for all the above reasons.

the only real down side is that because it doesn't absorb water, whatever water makes its way into the system is now free to wreak havoc. but regular maintenance intervals solves that problem.
