shnoof Posted June 10, 2009 Report Share Posted June 10, 2009 I water bleed my brake and in do it because its cheeper and i think it is easyer to bleed. Quote Link to comment Share on other sites More sharing options...
Luke_zoo Posted June 10, 2009 Report Share Posted June 10, 2009 You can push more water into your brakes then oil....Why pay £3-£5 for oil, when you can go the the tap or bath bleed ? Quote Link to comment Share on other sites More sharing options...
SunshineDiver Posted June 10, 2009 Author Report Share Posted June 10, 2009 Haha kl. I thought it had like some super tech advantage like made the brake feel more controllable . Quote Link to comment Share on other sites More sharing options...
Adam Griffiths Posted June 10, 2009 Report Share Posted June 10, 2009 water bleeds are more quick reacting than the oil because the oil is thicker. Quote Link to comment Share on other sites More sharing options...
forteh Posted June 10, 2009 Report Share Posted June 10, 2009 Its purely for lever feel, oh and slightly cheaper aswell You will eventually get sticky seals on the slave pistons but it takes a good few years to get that bad and can be resolved by bleeding with a water/oil emulsion.IMHO its as easy to bleed brakes with water or oil, water is a bit easier to clean up if you spill any. I always syringe bleed anyways as its the most sensible option if you have a bleed kit. Quote Link to comment Share on other sites More sharing options...
lankyri Posted June 10, 2009 Report Share Posted June 10, 2009 found it very easy with water as you can fill up your sink with water bleed it whislt under water and if done correct you will not have any air in the brake making the brake feel much nicer, also water is thinner than oil so there is less friction going through the hosing meaning you have a better response at the slaves. but it is just down to your own choice but i prefer water over oil downside is that during the winter water will freeze where oil would still be fine Quote Link to comment Share on other sites More sharing options...

in_aww Posted June 10, 2009 Report Share Posted June 10, 2009 I have beeen using a water bleed for a little over a year now and I prefer it over oil and WD40 which I've also used. In terms of simplicity, bleeding with water is about as simple as it gets.I fill the sink up give the system a few pumps and its done. Alot of people have mentioned that it can damage seals and cause your pistons to stick. I have not had any problems with this. I do, however, add a fair amount of anti-freeze to the water and I was told this helps act as a lubricant for the seals and such. I also lubricate the pistons(from the outside) with a little oil every now an then. Regardless, its worked well for me and they are much "snapier" than when bled with oil. Give it a go!!

jack vickers Posted June 11, 2009 Report Share Posted June 11, 2009 i only use water if i dont have the mineral oil but if air gets in it will make it rust and will brake your brakes thats what i have been told Quote Link to comment Share on other sites More sharing options...
