J Trials 31 Posted September 24, 2008 Report Share Posted September 24, 2008 Out of blood and don't like the feel of water. Was told DOT 5 works good. Can anyone confirm this? Quote Link to comment Share on other sites More sharing options...
that NBR dude Posted September 24, 2008 Report Share Posted September 24, 2008 Dot 4/5 will eat your seals. The seals used in Maguras are designed for mineral oil. Don't bleed your brake with Dot, as it will leak Quote Link to comment Share on other sites More sharing options...

J Trials 31 Posted September 24, 2008 Author Report Share Posted September 24, 2008 What about Pentosin oil for central hydraulic systems. Either CHF 7.1 or LHM Plus. Used in German stuff such as BMW, Audi, etc. Quote Link to comment Share on other sites More sharing options...
that NBR dude Posted September 24, 2008 Report Share Posted September 24, 2008 (edited) Your best bet if you have no Magura Blood, its look in halfords for Citroen Mineral Oil, closest match to magural blood. ANything else, and I would be concerned about degrading the sealsLHM Plus will work fine actually as its a mineral oil Edited September 24, 2008 by NBRCycles Quote Link to comment Share on other sites More sharing options...

J Trials 31 Posted September 24, 2008 Author Report Share Posted September 24, 2008 Citroen stuff is probably out of the question since I live in the US and Citroen's were never really shipped here. Tried O'Reilly's for some stuff. They didn't have it. Do you think it's worth trying AutoZone and Advance Auto Parts? Quote Link to comment Share on other sites More sharing options...
JonMack Posted September 24, 2008 Report Share Posted September 24, 2008 Any mineral oil will be fine, just try and find the thinnest stuff you can. Failing that, use water. Quote Link to comment Share on other sites More sharing options...

Don't bleed your brake with Dot, as it will leakDOT 3 and 4 are glycogen based. DOT 5 is silicone based. They are completely different. They use DOT 5 in Hope brakes, so why wouldn't it work in Maguras? Seals should be no problem with the silicone base. Quote Link to comment Share on other sites More sharing options...
RossMcd Posted September 24, 2008 Report Share Posted September 24, 2008 try baby oil! that works Quote Link to comment Share on other sites More sharing options...
J Trials 31 Posted September 24, 2008 Author Report Share Posted September 24, 2008 try baby oil! that works Would rather try DOT 5 than baby oil! Especially right now. Might have a demo to do in a couple of hours and don't have a rear brake. Quote Link to comment Share on other sites More sharing options...
craigjames Posted September 24, 2008 Report Share Posted September 24, 2008 doesnt matter what dot fluid you use its corrosive and therefore will eat your maggie seals which are designed for mineral oil. magura blood, thin mineral oil or water, your best options.

J Trials 31 Posted September 24, 2008 Author Report Share Posted September 24, 2008 Could I mix what little bit of blood I have with something? Regular store mineral oil or water? Quote Link to comment Share on other sites More sharing options...
DrEvil270183 Posted September 24, 2008 Report Share Posted September 24, 2008 Hope you didn't bleed your maggie with any dot fluid. We had a guy in our shop just the other day, thought the warning on his shimano brakes saying mineral oil only was to stop you buying other brands oils so bled with dot 4. few hours later the seals died badly. very very costly for him. Dot fluid eats the seals in mineral brakes, and mineral oil isn't any good for seals in dot 3/4/5 brake systems either. I can't believe how many people come up with crazy ideas but won't bleed with water Quote Link to comment Share on other sites More sharing options...

DrEvil270183 Posted September 24, 2008 Report Share Posted September 24, 2008 bleed it with water only, not only will it be the best bleed but it will be the best feeling brake you've ever had. Very positive feel. Quote Link to comment Share on other sites More sharing options...

J Trials 31 Posted September 24, 2008 Author Report Share Posted September 24, 2008 Why not just use water? It works fine...Tried it about 10 times and could never get it to work as good. How much fluid is actually needed to bleed it. Got about half a bottle of the 2 ounce. But this is reused blood. Quote Link to comment Share on other sites More sharing options...

Mark W Posted September 24, 2008 Report Share Posted September 24, 2008 If you've got a track pump or air compressor it's really easy as you just blow air through it. If not, just take the brake off and the bleed bolts, and give it a good old shake. Usually worked for me. Either way, if you pump water through the system so it's been completely flushed through several times that should get rid of most of it, but then re-bleed it after a week or so and that'll get the last of it. If you empty it reasonably well first a water bleed should be fine. Just take your time with it and do it properly and it'll be fine - I know countless people, including myself, who've used water bleeds and found them to be really good, so there's no reason your's shouldn't work well.

J Trials 31 Posted September 24, 2008 Author Report Share Posted September 24, 2008 Yeah, done all that already before. Can't get enough power from it for it to even stop. It was real weird. So is that enough blood though. Gotta get the bike ready for my demo. Quote Link to comment Share on other sites More sharing options...
sstein Posted September 24, 2008 Report Share Posted September 24, 2008 I use cooking oil, feals exactly same as maggie blood but costs £0.75 for 2 litres. Quote Link to comment Share on other sites More sharing options...
JonMack Posted September 24, 2008 Report Share Posted September 24, 2008 Could I mix what little bit of blood I have with something? Regular store mineral oil or water?You do realise you should never mix oil and water because of their viscosity difference?Also, if you can't bleed with water, you're doing something very wrong.

Mark W Posted September 24, 2008 Report Share Posted September 24, 2008 *stuff*Then it sounds like it wasn't bled right? If it's bled right, it works better than Magura oil. There's not really much more I can say that than, because that's all there is to it?If you've got that Magura blood and there's no other option apart from water, what have you got to lose by trying to see if that amount of oil works?
