jj65 Posted June 9, 2015 Report Share Posted June 9, 2015 I have a Magura slave cylinder for the clutch, be Magura say you can ONLY use mineral oil, Dot 4 will destroy the seals. I am using a Braktec clutch master cylinder, the plastic cap does not have any marking on it, unlike the front brake master cylinder, which has Dot 4 stamped on it. Will mineral oil cause any problems with the Braktec clutch master cylinder seals (I'm assuming it won't as it doesn't contain any acids, unlike Dot 4). I believe some new bikes use mineral oil, but I'm not sure. Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
copemech Posted June 10, 2015 Report Share Posted June 10, 2015 Seals MUST be compatable with the fluid-period! Call them if unsure what is in it! Or change seals in the slave to match. Quote Link to comment Share on other sites More sharing options...

It's not possible to change the seals in a Magura slave cylinder, so I'll have to change the seals in the master cylinder. Quote Link to comment Share on other sites More sharing options...
