DOT4 v DOT3?
Is there any particular reason why I shouldn't use dot3 and opt for dot4 other than a slightly higher boiling point?

DOT 4 Is a little better also for not collecting as much moisture

Wait!
You might not want to mix different types of brake fluid without first checking to make sure there compatible. I'm not sure about DOT 3 + 4 but I know your not supposed to mix DOT 5 with anything else. Bad thing happen, so I've been told.

mixing dot 3/4 are fine... stay away from adding 5... you can add 5.1 but will dilute the higher boiling point.
