Krisboats Posted March 14, 2007 Report Share Posted March 14, 2007 10+ bleeds over about 4 months... worse every time. lubed seals and everything.ended up getting a new brake, it was a few years old..Sorry, it wasn't aimed at you. I know you know what your on about. Usually does the trick when it happens though. Quote Link to comment Share on other sites More sharing options...
Elliot Posted March 15, 2007 Report Share Posted March 15, 2007 it realy annoys me when people say aluminium rusts did/are any of you doing science at school. if you are you should know that only steel rusts iron oxide, aluminium when exposed with air get aluminium oxide coating, this protect the aluminium and all aluminium will have a layer, rust is only for steel, and oxygen has to be precent. anyway after that dont worry about rust with things made of aluminium!A fair point, except that its iron that rusts; steel rusts as its an alloy of iron (or so my hazy recollection of chemistry classes tells me). I was more coming from not knowing that the internals of the maggies are all aluminium. Quote Link to comment Share on other sites More sharing options...
Ghetto Rider Posted March 15, 2007 Author Report Share Posted March 15, 2007 By the way: Hated how the lever felt when pulling in (using water) now with some nice thick magura blood it feels nice.I like to know that the brake is on in my mind, if it feels funny or different I can't use it...

But you tried it and dont like it? how did it feel pulling in? Quote Link to comment Share on other sites More sharing options...
dave85 Posted March 15, 2007 Report Share Posted March 15, 2007 By the way, you don't need to bleed the brake if all you're doing is cutting the line down. Quote Link to comment Share on other sites More sharing options...
Elliot Posted March 15, 2007 Report Share Posted March 15, 2007 By the way, you don't need to bleed the brake if all you're doing is cutting the line down.I've read that before, but because I know how clumsy I am and because I had heard so many people do it and like it, I was thinking of bleeding with water at the same time. Thanks for the info anyway though dude!! Quote Link to comment Share on other sites More sharing options...
dave85 Posted March 15, 2007 Report Share Posted March 15, 2007 To give a different perspective, I absolutely despise water bleeds. Theyre nice and light, very snappy response to start with, but as the water and remains of the old oil emulsify, the seals and pistons dry out and it just feels rough. I've seen so many brakes bled with water, at a guess, 90% of them have shown a massive improvement in feel and response when bled with royal blood.

I've seen so many brakes bled with water, at a guess, 90% of them have shown a massive improvement in feel and response when bled with royal blood.But to be fair, if you bleed it and really flush the system out you have hardly any oil left in there to emulsify, then once it has, just rebleed and its gone. I find nice hot water foir the first water bleed is the best way to get the oil out fully, or if oil collects in the lever i give it a bleed with hot water and some washing up liquid then flush through with normal water afterwards.

Heatsink Posted March 15, 2007 Report Share Posted March 15, 2007 In all my years of riding ive heard of:Magura BloodHalfords Mineral OilCitroen Suspension fluid (these 3 are pretty much the same thing)WaterWater with Anti Freeze (watch the AF content as its highly corrosive)Distilled WaterWD40GT853-in-1 OilIm sure thees more out there somehwere.I would reccamend regular tap water.And for that special bleed that will feel the don, submerce bleed it in the bath.+ Baby oil is a mineral oil too. I was going to establish the viscosity (how "thick" fluids are) of a few popular choices but didn't find time. Experiments can be done with long perspex tubes and ball bearings!Tap water in the bathroom sink for the convenience and ease of avoiding bubbles in the system (the final sealing bolts can be done up underwater)Steve Quote Link to comment Share on other sites More sharing options...
Janson Posted March 16, 2007 Report Share Posted March 16, 2007 bled my brake with battery water last night. so far feels fine.battery water = distilled stuff without the ions and shit in it. dunno if it makes a difference, our tap water here is really clean, but it was like a quid for a litre so why not?
