If you switched your sys. to Dot 5 brake fluid how well does it perform. Is it as good as Dot 3 when stoping. Did you notice any difference in your pedal. Did you just drain your calipers and wheel cyl. or also flush the sys.

I am thinking of switching only because I have the master cylinder out and like the idea of not having to worry about Dot 3 (paint removal) after I am done with the engine and engine bay repaint and detailing. Thanks for your feed back.

I swaped about 5 years ago. I changed calipers to stainlesssteel, changed the rear wheel clyinders, and the front brake lines. My rear brake line was new so I just blew them out as best I could. At the same time my master clyinder was rebuilt. During the bleeding process I purged extra fluid throughout to ensure the other stuff i.e., Proportioning valve and the distribution blocks were purged. Everything is working good....however i should have rebuilt the Proportioning valve. Which i will do in the next few weeks.

It is suggested that you purged the dot 5 every year or so.

Hope this helps

I switched, I didn't really notice much difference in ferformance. I too was worried about paint revomoval if it splashed. it was a little more difficult to bleed out the system. But once it was bled it was OK.I did flush the system with Denatured alchohol and blew out the lines with air before filling. I also have been told not to use DOT5 if you plan to drive through high altitudes. Some Corvette guy told me he was driving through Denver and his wheel cylinders blew out. Seems this stuff vaporizes at high altitudes.

Unless you are in constant stop and go traffic where heat could be a factor I wouldnt worry about changing. Dot 3 is still used in todays cars with great results.

If you are thinking about making the switch go with DOT 5.1 instead of the DOT 5 stuff. The DOT 5.1 is compatible with the DOT 3, so flushing the system out is not as critical (still a good thing to do tho).
