fatty r Posted November 29, 2008 Report Share Posted November 29, 2008 as winter is pretty much here and for all the people with water bleeds i wondered if theres any tips for unfreezing them i already no not to use a kettle of water because its can split your slave sylindres and i only live with my old man so no hairdryers avalable any ideas cheers kyle Quote Link to comment Share on other sites More sharing options...
Skoze Posted November 29, 2008 Report Share Posted November 29, 2008 Put some antifreeze in 'em Quote Link to comment Share on other sites More sharing options...
Sidehop Stuart Posted November 29, 2008 Report Share Posted November 29, 2008 Do steel braided hoses also help to stop freezng? Quote Link to comment Share on other sites More sharing options...
Dan81 Posted November 29, 2008 Report Share Posted November 29, 2008 Use proper brake fluid? Im not sure why people have a problem with the stuff. Quote Link to comment Share on other sites More sharing options...
fatty r Posted November 29, 2008 Author Report Share Posted November 29, 2008 proper brake fluid is good i have no problem with it but it costs money and need a car so car comes first Quote Link to comment Share on other sites More sharing options...
grant_hundley Posted November 29, 2008 Report Share Posted November 29, 2008 Use proper brake fluid? Im not sure why people have a problem with the stuff.Water gives a better feel to the brake, returns quicker, easier to pull etc.It's also free and if you don't have the syringes etc, you can't exactly fill your sink with oil.......

Water may be free but so what if you can't use you bike when it gets cold. It doesn't cost that much for a proper bleed kit and oil....maybe if you can't afford to maintain a magura switch to a vee (just a suggestion) Quote Link to comment Share on other sites More sharing options...
Dave_Finney Posted November 30, 2008 Report Share Posted November 30, 2008 This is funny, lots of people bleed there maggys with water. "WHY!"?? mineral fluid is a lubricant, water is not. the feel of water is nice at first because its thinner than mineral fluid. hence the quick piston return etc. but sooner or later the pistons will go sluggish and will return slowly, the lever feel will be nasty and you will have just void your warranty. Put steel in water and see what happens, corrosion. Yet all magura fittings are steel so nice bit of corrosion from the inside out. Never good. And to top it all off water, (unless antifreeze added) freezes! And at this time of year thats not what you want!Get to halfords or alike get some mineral fluid and do the job right.. so many brake complaints on here yet so many people dont follow the simple manufacturers guidelines! there there for a reason!!£4.00 aint gonna brak the bank!!Dave Quote Link to comment Share on other sites More sharing options...
eskimo Posted November 30, 2008 Report Share Posted November 30, 2008 Water is fine. Corrosion doesn't happen over night though neither seizing. Just store your bike indoors over night. As when was the last time it was freezing and you went riding?? Quote Link to comment Share on other sites More sharing options...
Dave_Finney Posted November 30, 2008 Report Share Posted November 30, 2008 Yesterday!! haha, is it really worth it though. no one ever has any problems with mineral fluid but lots do with water. and corrosion wont happen overnight your right. but it will happen. also the compression chareteristics of water are different to those of mineral fluid.Bottom line, Use the correct fluid and your brake will last twice as long and wont play up. use water and it will be good for a while then the brake will be ruined, its been done many times "By myself too!"Dave Quote Link to comment Share on other sites More sharing options...
forteh Posted December 1, 2008 Report Share Posted December 1, 2008 My maggie has been water bled for the last 6 years, still on the same lever and slaves Its frozen once in all that time, mainly because I was riding at 11pm in winter - getting too old to do that now so its not really an issue.The corrosion also isnt an issue as there is this magical thing called oxygen that needs to be present to cause steel to rust, funnily enough there is bugger all oxygen in a hydraulic brake (ok discounting the minute amounts of oxygen in solution). Besides which, all of the steel fittings are open to atmosphere anyways and when was the last time you say a maggie with rusty fittings? The only problem Ive found with a water bleed is that the slave cylinder seals dry out a touch (as you mentioned), this is easily solved by dropping a spot of oil onto the pistons every couple of months.

Ashley-Wood Posted December 1, 2008 Report Share Posted December 1, 2008 water is free and easy mineral oil is money and feels horrible. antifreeze + water works better than mineral oil Quote Link to comment Share on other sites More sharing options...

Callum.Curwood Posted December 1, 2008 Report Share Posted December 1, 2008 Had a water bleed all last year and it never froze or sized.And the other day when it snowed, it was frezing. My bike was in the shed and I went to check on it, and it was fine Quote Link to comment Share on other sites More sharing options...
Simpson Posted December 1, 2008 Report Share Posted December 1, 2008 Proper brake oil is made for a reason though...like not freezing for a start...and I also thought its because water can be compressed more than a formulated brake oil. Water may be free but so what if you can't use you bike when it gets cold. It doesn't cost that much for a proper bleed kit and oil....maybe if you can't afford to maintain a magura switch to a vee (just a suggestion)Thats why some people chose to put anit-freeze in with there brakes... i always used to keep my bike in the garage and never ever had a problem with freezing out on rides.. and water cant compress in a sealed system, (well obv it can but its farily negligable when compared to the pressues that our small plasic hoses provide.)Anit freeze is free, if your parents own cars, you literally need less than half and half and you only need like 50ml to bleed a whole brake... bleed kit costs about a tenner, and oil is a fiver, so 15 quid and you have to wait for bits to arrive and you have to leave the house... or you can put it in a sink and do it straight away, also on a ride if your brake goe's, no-one will carry oil with them, and it will get messy and it will be a massive pain in the ass. thats not mentioning the benifits of the responsivness of water, because of its viscosity.even if it does void your warrantee, if you bleed it with mineral oil before sending it back how will they ever know anyway/ and it wont corrode your seals because there should be no air in the system... seriously ever one does it for a reason and it is worth it, ive had a water bleed for years with no problems occouring. to stop sluggish pistions you should oil the pistions... not oil the internals.also the compression chareteristics of water are different to those of mineral fluid.doesn't matter... your frame will flex to the point of snapping before the water compress's.....

Dave_Finney Posted December 1, 2008 Report Share Posted December 1, 2008 Lots of scientists on here!! lol, na your right about corrosion etc but seems funny that the majority of people with problems.. "sluggish pistons" etc are using water to bleed the system.But antifreeze if you insist on using water! is deffonatly a good idea.Dave Quote Link to comment Share on other sites More sharing options...
Ali C Posted December 1, 2008 Report Share Posted December 1, 2008 if I used a maggie, I would have to run water simply because I get stupid amounts of arm pump with normal fluid.Also, liquids can't be compressed, so there's no difference between oil and water.

Oily mess over rims/disc...Hellooooo contamination. Quote Link to comment Share on other sites More sharing options...
Dave_Finney Posted December 2, 2008 Report Share Posted December 2, 2008 Ok, serious question scientists!! how come if you fill a bottle of water to the brim, no air in it at all.. and freeze it. it will explode due to water expanding as it freezes yet magura systems dont explode "split lines etc" when they freeze??Dave Quote Link to comment Share on other sites More sharing options...
grant_hundley Posted December 2, 2008 Report Share Posted December 2, 2008 Because the pistons move out.Put a hole in that lid and put a tube or straw etc in the whole into the bottle.Now freeze it...Work it out, scientist. Quote Link to comment Share on other sites More sharing options...
Dave_Finney Posted December 2, 2008 Report Share Posted December 2, 2008 Haha, nice bit of sarcasm thrown in for good measure! appreciated. but....water can be compressed like anything else. It's just that the molecular structure of water is so dense that it takes extremely high pressure and the amount that it can be compressed is relatively little. Water is an extremely simple molecule but it has extremely unique properties. It called the universal solvent because more substances will dissolve in water than anything else. There have been entire books written on the properties of water alone.And thats how bored i am!Dave Quote Link to comment Share on other sites More sharing options...
grant_hundley Posted December 2, 2008 Report Share Posted December 2, 2008 (edited) Err, what's your point? Edit: didn't mean to seem rude, just can't understand your point? Edited December 2, 2008 by Bob Fossil Quote Link to comment Share on other sites More sharing options...
Dave_Finney Posted December 2, 2008 Report Share Posted December 2, 2008 (edited) Dont really have one to be honest other than someone said it cant, Anyway this is way off topic. Funny to see how opinionated people get on here though! especialy about something like oil or water in your brakes!!!Dave Edited December 2, 2008 by Dave_Finney Quote Link to comment Share on other sites More sharing options...
