Running magura's on water?

[Broken Biker]

Only downside to using water is you'll have to bleed them regularly because of the 'O' in 'H2O' - the braking pressure causes it to seperate...

Surely this is only in Hydroxil and atomic oxygen which will quickly reform, hardly going to lead to gas pockets I would have thought?

My biggest concern would be with corrosion within the brake's moving parts, however, if all is well anodised this should not be a problem. Using water is fairly enviro friendly if you ever pop a line though! :roll:

Water has air in it, hence H2O, and the internal pressure during braking causes it to seperate, hence having to bleed it off when the brakes get 'spongey'- Google it...

Motorcycle brakes use oil (hydraulic fluid) because it has a higher boiling point than water, oil absorbs water under the pressure of braking, water has air in it - that's why you have to bleed your brakes...

I though brake fluid is hygroscopic, hence the necessity to change brake fluid every so often as the water makes your brakes feel spongey. Surely if all of your 'brake fluid' is water, your brakes will always feel spongey?

There's no lubrication properties in water either, so surely any metal on metal interfaces in your braking surfaces will wear quicker?

Maguras dont use brake fluid they use mineral oil.

...because brake fluid attacks the seals in Maguras

If brake fluid was used to lube any moving parts in the system it would follow that it would leak out...

Errr, water has air in it?

Technically water is an oxide of hydrogen... DiHydrogen Oxide. When this molecule breaks down, it is into Hydroxil and Atomic oxygen, which requires great energy to do.

Hydraulic fluid is hydroscopic and will absorb water, this is why brake fluid on my Streetfighter was changed after so many years of use. I fitted custom made stainless hydro lines to replace the standard reinforced rubber hose because this removes spongyness from bike brakes. Try bleeding a double set of six pot Tokico callipers and seeing if they still feel spongy!

I can talk b*ll*cks for hours! Especially when I've been up since twenty past four this morning

Just read back what I typed more than once; hmmmm, need more sleep!

Should have said oil absorbs air, air has water in it - got it completely arse about face; twice! :roll:

I wondered why it didn't sound right at the time...

...I'll go back to my guitar parts on eBay and leave this to people who can string more than two words together and still make sense!

I am really thinking about this as well as you but using a little anti freeze as mentioned from someone else it looks really easy think this will really work well

If I may make a suggestion : use distilled water rather than tap water. Distilled water is a lot more pure. No minerals, no calcium, etc.

I'm not even going to mention Heavy Water!
