rickyb Posted March 13, 2006 Report Share Posted March 13, 2006 Hay dude, yeah you can use water and it will IMO work better, but if you have a bit of de-iser you shold use that aswell as water but if not then don't leave it outside for a long time when it's cold or it will frezze but that is an easy thing to sort out. so good luck with it mate a lot of riders i know use water and wouldnt go back to maggie blood rickyb Quote Link to comment Share on other sites More sharing options...

Lee Cable Posted March 13, 2006 Author Report Share Posted March 13, 2006 thanks mate, yea i shall sling some de icer in there , Im sure that my dad will have some in the car. This will stop them from freezing, but will it affect my brake performance at all? Thanks from Lee Quote Link to comment Share on other sites More sharing options...
bee_ Posted March 13, 2006 Report Share Posted March 13, 2006 I'm sure it's a bad idea to use water in a disc brake.. Quote Link to comment Share on other sites More sharing options...

rickyb Posted March 13, 2006 Report Share Posted March 13, 2006 No it shouldn't but it will deter the life of the brake as you would exspect but if it dosen't feel any better then you should go back to the maggie blood because that will give you a working brake for longer.rickyb Quote Link to comment Share on other sites More sharing options...

poopipe Posted March 13, 2006 Report Share Posted March 13, 2006 it'll fack your 5 year anti-leak warranty (assuming you remembered to register). just so you know.. Quote Link to comment Share on other sites More sharing options...
Andy King Posted March 13, 2006 Report Share Posted March 13, 2006 using water in hydraulic brakes keeps coming up on here,generally its a bad idea, you need the correct oil in all brakes for lubrication etcalot of people use it in hs33's,but you MUST bleed regularly, and MUST add anti freeze, but its still abad idea!! (alot of stuborn people on here will say otherwise though?!?) NEVER EVER EVER use water in a disc brake though, amongst other things, disc brakes generate a huge amount of heat, water will just boil off andbecome useless! also it will rust and then seize the piston in the caliper body!Just dont be a cheapskate and use the proper stuff for the proper brake,its onlycheap anyway!!cheersAndy King Quote Link to comment Share on other sites More sharing options...
CurtisRider Posted March 13, 2006 Report Share Posted March 13, 2006 as i have already said lee, this is only until i get a chance to bleed it properly for you waters only a problem when it freezes and if you heat the brake up alot-which you wontalso in regards to warranty-there isnt 1-its an old clara calliper connected to a brand new gustav lever(and seems to work pretty darn well )its only a temp fixde icer could be a good idea, unless you keep you bike in your nice warm house-use your brothers firey ginger hair to warm it up Quote Link to comment Share on other sites More sharing options...
nmt_oli Posted March 13, 2006 Report Share Posted March 13, 2006 Ok, water can safely be used in maggies as regard to seals. In a disk brake i would only use water as a tempory measure- they feel much more snappy and positive than rim brakes anyway, so theres not that argument for the water.Water can be DANGEROUS in a disk brake, as if you ever get it the slightest bit hot (and its surprisingly easy to do) the water will vapoourise (temporarily), this will leave you with no brakes, and possibly damage the system due to a huge pressure build up inside the system.The worst thing is how quickly this can happen- if your going down a hill with the brake on and it is getting hot, the water will not vapourise until you release the lever as the pressure your are putting on the system prevents the water expanding into vapour, and hence the water heats up past its boilign point. as soon as you release the lever, pressure is reduced and you get vapour in the system leaving you with complete brake failure until the brake coold down- which will take a good 10 mins at least.

Lee Cable Posted March 13, 2006 Author Report Share Posted March 13, 2006 (edited) as i have already said lee, this is only until i get a chance to bleed it properly for you waters only a problem when it freezes and if you heat the brake up alot-which you wontalso in regards to warranty-there isnt 1-its an old clara calliper connected to a brand new gustav lever(and seems to work pretty darn well )its only a temp fixde icer could be a good idea, unless you keep you bike in your nice warm house-use your brothers firey ginger hair to warm it up yea...but that could be ages, so i thought i would do a water bleed, and now its still exactly the same, im sure you sold me a dodgy brake.... naa its gd, probably just need's bleeding by a pro (paul )Thanks from lee Edited March 13, 2006 by radical rider Quote Link to comment Share on other sites More sharing options...
