sunn_bmixx Posted June 20, 2006 Report Share Posted June 20, 2006 it will as the hose is black it conducts alot of heat in the summer. You think if you leave a bottle of water in the sun you get lots of little bubbles inside it. This will happen inside your brake. Consequently creating an air bubble. Use oil as this is what the brake is designed for?Ian Quote Link to comment Share on other sites More sharing options...

Use oil as this is what the brake is designed for?Ian In 2 years of using a Magura with water in it, I have never had that happen to me. In a sealed system which is exclusively filled with water, it'd have to get a shitload hotter than your bottle of water was getting to heat it up. Don't forget generally bottles are clear, and thinner than Magura hosing too, so that'd effect it. Either way, the water evaporating hasn't happened to me before...Anyway, click on that poll link I posted earlier. Over 50 people (bearing in mind they're just the people who voted in that poll, and I KNOW more people use water than that...) use water, so it's not like it's untested or anything...Magura don't make a 4-bolt booster (the Evo2 design isn't one ), and the brake also comes with black pads. How many people here still use black pads on their brakes? I'm willing to bet you don't. They say you should only use their fluid too, which retails at £20-25 per litre. The same fluid is available with other names on it for £6. They want you to use their simply so they make more money. Mineral oil seals can also hold water. Therefore, you can also use water in them. The internals won't rust unless you have air in your system, the cables can't "go manky" as someone once told me mine would simply because they're made of plastic, or have a plasticy liner if you get braided ones. There is nothing wrong with using water in your brake. Before I used anti-freeze, mine froze up. All it did was move the pads further towards the rim as the water expanded as it became ice. This isn't a drama. Quote Link to comment Share on other sites More sharing options...
N.Wood Posted June 20, 2006 Report Share Posted June 20, 2006 This thread is a shambles!Christ... I agree wholeheartedly with what Mark has said. And getting down to whether water breaks down to hydrogen and oxygen, along with talk of black hoses recieving more insolation than a clear hose, along with arguing about 16 grams.... f**k.

Towesie Posted June 21, 2006 Report Share Posted June 21, 2006 you can use water to bleed them, the only problem with water is that it slowly degrades the oil seals in the brake, if you use a small amount of anti freeze in the mix it will make the seals last longer, and stop the water freezing in the winter, you should be careful when using other thinner types of oil, make sure the oil you are using is mineral based, any other oil such as dot 4 or 5.1 will destroy the seals, Quote Link to comment Share on other sites More sharing options...
nigel@hull_trials Posted June 22, 2006 Report Share Posted June 22, 2006 (edited) WATER OR OIL THERES NO COMPETITION THERE WATER EVERY TIME because FEELS BETTER, QUICKER REACTIONS Edited June 22, 2006 by nigel@hull_trials Quote Link to comment Share on other sites More sharing options...
Danny Kearns Posted June 22, 2006 Report Share Posted June 22, 2006 Well water i would say, quicker reactions at the leaver and overall more power in your brake. Dan. Quote Link to comment Share on other sites More sharing options...
