murph82 Posted November 28, 2010 Report Share Posted November 28, 2010 So to be proper about this, does anyone know of an oil so thin its like water? I had to replace a slave cylinder piston after leaving a water which froze last winter a couple times, but then didn't ride for months and it wouldn't return.i rang magura uk to be told water is just about ok if used regularly but it will corrode the pistons after some time. I've got monty from tarty in mine at the moment and the stroke feels a lot thicker,i dont like it! Is there a proper alternative to any kind of water bleed?

Mark W Posted November 28, 2010 Report Share Posted November 28, 2010 If I bleed it with dilute anti-freeze, will that be ok yeah? - Basically water and anti-freeze anyway. You can pretty much freestyle the ratio. It really doesn't matter much. I've used a pure anti-freeze bleed before and it worked just as well as any 'pure' water bleed I've done, except obviously I could use my brake in the winter...

Ok, is mineral oil better? - Because I got told loads of times today at the comp to bleed it with mineral oil! Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 28, 2010 Report Share Posted November 28, 2010 if you want a slow returning arm pump inducing brake, then mineral oil is fine. Otherwise just put some anti freeze in and tell the people at comps that you don't always have to do what you are told. Quote Link to comment Share on other sites More sharing options...

Wasn't as quick as water, but you know. Anti-Freeze it is then Thanks!! Quote Link to comment Share on other sites More sharing options...

Revolver Posted November 29, 2010 Report Share Posted November 29, 2010 Reverse Osmosis water. Sounds like it's water that's been filtered to leave it as H20 and nothing else. Thus, no nasty salts or other chemicals that corrode your seals. Quote Link to comment Share on other sites More sharing options...

Sponge Posted November 29, 2010 Report Share Posted November 29, 2010 Antifreeze appears to work fine by itself, but IF you want to still try out some mineral oils... then Baby Oil is the first stop. I haven't used it myself yet but I always hear that the lever feels a lot snappier and reponsive, whilst it being mineral oil which doesn't corrode anything incase you're worried in the long term. I should think a bottle of baby oil is cheaper than anti freeze of the same volume, so why not try it out? If you don't like it, then anti freeze away. Since it's Baby Oil, even if you don't get on after testing it'll at least be somewhat of use other than for bleeding brakes... Quote Link to comment Share on other sites More sharing options...
Sam Moss Posted November 29, 2010 Report Share Posted November 29, 2010 A lot of good info in this thread 1. Brake should be fine - Mines frozen and after it thawed it it was fine. 2. Can bled with water / antifreeze mix. Probably 50:50 ratio, but whatever. Brake will be fine. someone told me the antifreeze would do somthing to the seals on the brake. not sure if its true Quote Link to comment Share on other sites More sharing options...
Mark W Posted November 29, 2010 Report Share Posted November 29, 2010 It isn't, in pretty much the same way that almost everything people say about the seals on Maguras brakes - or Magura brakes in general - is usually completely wrong...

LukasMcNeal Posted November 29, 2010 Report Share Posted November 29, 2010 Where's the traditional vees don't freeze Ali? Quote Link to comment Share on other sites More sharing options...
Mark W Posted November 29, 2010 Report Share Posted November 29, 2010 I have a feeling the masses of scaffolding required to run a V-brake on a 4-bolt frame, as well as the way that V's 'shake' and hit your rim when you land spins and the like, have meant Ali's 'changed his viewpoint' you might say. Or 'sold out' to put it another way Quote Link to comment Share on other sites More sharing options...
casualjoe Posted November 29, 2010 Report Share Posted November 29, 2010 Some of you may find this interesting, this My lazy pistons were brought back to life and the brake still works perfect. Do not use baby oil, the pistons gunk up after a while. Quote Link to comment Share on other sites More sharing options...
Revolver Posted November 30, 2010 Report Share Posted November 30, 2010 Phatphluid promises the same type of performance as that emulsion. Quote Link to comment Share on other sites More sharing options...
Mark W Posted November 30, 2010 Report Share Posted November 30, 2010 Mainly because from what Mike's said about it before, it sounds like it's going to be pretty similar to that (although not exactly the same, obviously...). Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 30, 2010 Report Share Posted November 30, 2010 Where's the traditional vees don't freeze Ali? VEES DON'T FREEZE! But yeah, as Mark said, I have sold out and am running a magura. If I was still a "traditional" rider, I would most definitely still be on a rear vee. Quote Link to comment Share on other sites More sharing options...

forteh Posted December 2, 2010 Report Share Posted December 2, 2010 Im still using my emulsion and not had any problems with sticky pistons in the last 18 months Ive been using it. Had to top the bleed up a few times as my RB has started weaping but its not a huge amount or hassle. Ive not tried it in subzero conditions yet (because Im old and the cold gets to me bones ) but I dont think there would be any significant problems with freezing Quote Link to comment Share on other sites More sharing options...
Julius Czar Posted December 2, 2010 Report Share Posted December 2, 2010 My brake is fine in the cold, its still got the original oil bleed, but every now and then, it seems to go really thick and takes ages to return? Sorry to steal the thread, just thought as we were on the subject Quote Link to comment Share on other sites More sharing options...
