Snopczynski Posted March 30, 2007 Report Share Posted March 30, 2007 i just filled my rear master cylinder with dot3....now i see the manual says to use 4.......is this a problem? can i leave it or should i order some new fluid? Dot 4 has a higher boiling point and its a silica based brake fluid. I would change it. Quote Link to comment Share on other sites More sharing options...
