Brake Fluid

Does Polaris make Dot 3 brake fluid, or have they upgraded to Dot 4? I checked at my dealer and they only had Dot 4. The guy at the dealer said that Polaris is always upgrading their liquids (oils, fluids, etc), so they may have quit making Dot 3. My ATV says to use only Dot 3, but is Dot 4 ok to use? Thanks

absolutely, you can always go up in DOT fluid, you just cant go down. Any machine that requires DOT3 can use a DOT4 because a DOT4 has a higher boiling point. But if your machine required a DOT4, you wouldnt want to use a DOT3, as you may boil the DOT3 fluid....so you can use the DOT4 no problems.

Now, DOT5 and DOT5.1 you need to starting checking labels, because some are a mineral oil and that woundnt work. But a DOT4 will be just fine.

No problem! I just recently did all of this. I flushed the brake fluid in my truck as well of my motorcycle on the same day. My motorcycle needed a DOT4, my truck only a DOT3, so I bought a few big bottles of DOT4 and put it in both the bike and the truck a few thousands miles ago, and everything has been working as good as new.

Also, on this subject, I recommend investing $30-$50 in a Might Vac. (Shop around, prices vary on the same exact device a lot). It will make bleeding your brakes so easy compared to the pump and crack open method.

It pulls brake fluid through the line, instead of trying to push it out the traditional way. Its easier, cleaner, faster, and you use less brake fluid to do it with.

These are what I am talking about --->>> http://www.google.com/search?hl=en&s...-s2g3&aql=&oq=
