DOT 5 is incompatible with DOT 3 and DOT4 fluid. It is used by racers but for reasons discussed to death should not be used on road bikes (Short answer is it does NOT absorb moisture, so water collects in the system). DOT 5.1 fluid is a higher rated DOT 3/4 type and is fine to use, if a little expensive from some outlets.
In short DOT 5 probably not what you're after
DOT 4 or DOT 5.1 are fine.
