Ben John-Hynes Posted January 2, 2010 Report Share Posted January 2, 2010 Ladssssssssss. Possible to bleed a maggie with GT85? Water will freeze, antifreeze/water won't be any good forr the seals. Hate the feel of oil. Ideas? Quote Link to comment Share on other sites More sharing options...

Water will freeze, antifreeze/water won't be any good forr the seals. Hate the feel of oil. Ideas? Meh, I've been running water for past 2 weeks, its been freezing up here, and my brake hasn't frozen. What do you normally bleed with? EDIT: I forgot, I run braided hosing, so that probably helps a lot. Edited January 2, 2010 by DannyBazz (: Quote Link to comment Share on other sites More sharing options...
Ben John-Hynes Posted January 2, 2010 Author Report Share Posted January 2, 2010 Used to be water, but it started f**king my seals. Quote Link to comment Share on other sites More sharing options...
DannyBazz (: Posted January 2, 2010 Report Share Posted January 2, 2010 Used to be water, but it started f**king my seals. Hmm. Whats your set up? Deng or all maggie etc.? And, How old is the brake? pre 05? It could just be getting old, and I've heard after about 2 years water does start to mess with your seals...

eep803 Posted January 2, 2010 Report Share Posted January 2, 2010 Check out wiki or google gt85/wd40. I'm pretty sure they're 80% or so solvent and a little bit oil. The solvent is designed to be very "thin" (low viscosity) and "wettable" (spreads out over surfaces) and is possibly non-polar so that it displaces water. I've never used it but my hunch would be that you may have trouble with it leaking out and losing its volume. Also I'm not sure how well the solvent would take the pressure and may gas off in warmer/high pressure situations. I could be very wrong though Quote Link to comment Share on other sites More sharing options...
Brisa Posted January 2, 2010 Report Share Posted January 2, 2010 I would say anything with nasty solvents (stuff that tends to smell nice like gt85) shouldn't be used in a magura. They are a mineral oil brake and the seals won't take kindly to petrolium based products. We had magura technical guy over giving us a rundown on the forks and brakes tech for 2010 last month and I asked him about the water in a magura thing. He said it would not damage the seals it just wouldn't offer them any lubrication. If you were to rebuild your master and slaves giving a coat of silicone lube on the seals then bleed with water you will have a nice feeling brake that should move freely for a long time. Not sure what you could add to stop it freezing that won't play havoc with the seals but I have been running water in maguras and ridden on some silly cold days without any issue.

Shaun H Posted January 2, 2010 Report Share Posted January 2, 2010 You could make an emulsion. Although isn't that what you have already? Quote Link to comment Share on other sites More sharing options...
trialsmax04 Posted January 2, 2010 Report Share Posted January 2, 2010 Yes it will work, however GT85 isnt the exact right stuff. You need to look for "duck oil". Its wd40/Gt85 just in a liquid form. I ran it for over a year, no problems atall. max Quote Link to comment Share on other sites More sharing options...
the trials mop Posted January 3, 2010 Report Share Posted January 3, 2010 ive always wondered if you let beer go flat then bled with that what the result would be, as you would have a similar feel to water but with the alcohol to lower the freezing point Quote Link to comment Share on other sites More sharing options...
quick_spider Posted January 3, 2010 Report Share Posted January 3, 2010 ive always wondered if you let beer go flat then bled with that what the result would be, as you would have a similar feel to water but with the alcohol to lower the freezing point Why not just use antifreeze then?

N.Wood Posted January 3, 2010 Report Share Posted January 3, 2010 Waste of beer though... To be honest, I'd rather put 22p Tesco value lager in my brake than my body. Quote Link to comment Share on other sites More sharing options...
