As far as the problem the OP had, I said DOT 3/4/5 would make no difference and I stand by that statement.

The main difference between DOT 3 and 4 is the boiling point.
Dot 5 is silicone brake fluid and should NEVER be used for daily driven street vehicles, but I guess you learned the hard way and figured that out.
