vlad_b Posted January 5, 2012 Share Posted January 5, 2012 I have a sealed can of BLUE ATE brake fluid which is about 7 years old. Can I use it or do I have to shop for new? Just need it now and would be nice not having to wait for shipping. Thanks Link to comment Share on other sites More sharing options...
AZP Installs Posted January 5, 2012 Share Posted January 5, 2012 As long as it is sealed I don't see any immediate problems although we never have fluids on the shelf for that long. Brake fluid is hyrdoscopic (sp?) which means it will absorb water over time if exposed to air. This affect is intensified as you go from DOT 3 to DOT 4 etc etc. I would say give it a shot and if the pedal feels like junk have a back up bottle of fluid. -Jake http://www.pbase.com/paisan/image/91072632.jpg http://www.pbase.com/paisan/image/133406601.jpg http://upload.pbase.com/image/137566671.jpg Call directly for your best Whiteline Price! | We also carry almost every manufacturer now, so before you buy parts call us.

magnetic1 Posted January 5, 2012 Share Posted January 5, 2012 Youre a tad better off w/ the ATE since it is in a metal can, but 7 years is quite a long time. If it is for a street car, I doubt there will be any issues. Free Sonax Cleaner Deal http://www.brakeswap.com Carbotech, Hawk, PFC, DBA Rotors, Motul, Wilwood, Castrol... Great service.

iNVAR Posted January 5, 2012 Share Posted January 5, 2012 7 years? Wow... Well, the can is supposed to be airtight, and it's metal, so water shouldn't be diffusing into it... I bet it'll be fine. Any corrosion on the can? Link to comment Share on other sites More sharing options...
chutrain Posted January 5, 2012 Share Posted January 5, 2012 I have a can sitting for about 3-4 fours years on my shelf as well. If it is sealed, it should be fine. It's the ones that have been opened that you need to ditch. As Jake mentioned above, you might as well give it a go and not chuck something that might still be good. You are just losing a little bit of time if you have to redo. Link to comment Share on other sites More sharing options...
vlad_b Posted January 5, 2012 Author Share Posted January 5, 2012 It was left from my days with z350. There is some corrosion on the can. Not much though. I guess I'll try it. I don't think the air/moisture can get through seal. Link to comment Share on other sites More sharing options...
Mr. Sinister Posted January 8, 2012 Share Posted January 8, 2012 I used a sealed can that was as old or older with no problems (street only car). Link to comment Share on other sites More sharing options...
