Dot 3 brake fluid
I just bought some brake fluid for my 1992 RR Classic. As I went to put it in I saw the note on the resevior said, "Dot 4 Only"... and I have Dot 3. I have no idea what the difference is between these... Am I going to hurt my brakes by adding Dot 3 to the Dot 4 that is apparently in there?
