jbooker82 Posted May 25, 2008 Report Share Posted May 25, 2008 the question is on the title. Dot 3 or Dot 4. really need t know. It says on the res cover. Get a fuild that is compatable with dot 3 or 4. You can pretty much mix them. You just can't mix dot 5 with anything. Quote Link to comment Share on other sites More sharing options...
rubberneck Posted May 25, 2008 Report Share Posted May 25, 2008 Has anybody flushed their system out and put straight DOT 5 in? The cool thing about DOT 5 is it doesn't attack paint. I run in it my Baja and it has saved the frame and calipers a couple of time from some oops when filling or bleeding the brakes. Quote Link to comment Share on other sites More sharing options...

I am usually good about getting some simple green or somethig to wash it off but not always. Quote Link to comment Share on other sites More sharing options...

If I had PC'd everything I probably wouldn't worry about it, but I painted everything with 2 stage, so im a little paranoid. Quote Link to comment Share on other sites More sharing options...
EastCoast Banshee Posted May 25, 2008 Report Share Posted May 25, 2008 I use DOT5 now and it seems to work great. Its not harsh at all compared to dot 3 and 4, you can actually get it on you skin and paint and it doesn't eat away at it. Other than that breaking performance didn't really change.

jbooker82 Posted May 26, 2008 Report Share Posted May 26, 2008 Dot 3 + 4 keep moisture suspended, while dot 5 wont. So Moisture collects at the lowest point in the breaking system, the bottom of the calipars. Water Boils 212 deg. Minimum Boiling point for Wet Dot 4 is 311 deg. I run Motul DOT 5.1 Non Silicone Base, 100% Synthetic It has the high boiling point like regular silicone base DOT5, but doesnt allow moisture to collect at the bottom of the brake system. Best of both worlds... You can use it in brake systems specifing DOT3, DOT4 or DOT5.1 http://www.rockymountainatv.com/productDet...odFamilyId=3359 Quote Link to comment Share on other sites More sharing options...
