Ben John-Hynes Posted September 14, 2008 Report Share Posted September 14, 2008 You can't use those brakes with a water bleed. They need oil! Quote Link to comment Share on other sites More sharing options...
nrees16 Posted September 14, 2008 Author Report Share Posted September 14, 2008 so if i rebleed them with oil they will be as good as new? Quote Link to comment Share on other sites More sharing options...
Ben Cox Posted September 14, 2008 Report Share Posted September 14, 2008 no, the seals on them are shite! you will have to get new seals for it. email tartybikes, they may service it for you. Quote Link to comment Share on other sites More sharing options...

blaze_ Posted September 14, 2008 Report Share Posted September 14, 2008 The problem is not with the seals, even if you changed them things won't be fine. You have to grind the cylinder and then it might work fine and of course with mineral oil. Quote Link to comment Share on other sites More sharing options...

blaze_ Posted September 14, 2008 Report Share Posted September 14, 2008 Well anyone that opened an Echo brake could tell that it isn't from the seals and it looks like you haven't. The thing is that because it is idiotic cnc aluminum the water somehow ruins it (yeah I don't have a better word for that) and the cylinder isn't "fresh" anymore (yeah I'm not good with the words). And that's why they leak because they have small scratches which are caused by the water. The Magura ones don't have the same problem because they aren't aluminum only. They have another compound and are a completely different alloy. So grinding it means to make it "fresh" again. You have to use sandpaper (around 1000-1200) so that the cylinder doesn't have the scratches anymore. And if you make this thing one-two-three times you will have to change the seal, because the diameter of the cylinder changes and bla bla bla.Am I being specific now?

Alex Dark Posted September 15, 2008 Report Share Posted September 15, 2008 if you still have problems id swap an 04 magura for the echo brake Quote Link to comment Share on other sites More sharing options...
Bigman Posted September 15, 2008 Report Share Posted September 15, 2008 I have heard that the first batch of echo brakes had a problem where the inside of the master cylinder was not cleaned properly after machining, leaving bits of swarf in the brake, they were then filled with oil and when used the master cylinder will pick up the swarf and cause the scratchs in the cylinder, when run with oil there would be only a small leak, but if ran with water because it is thinner it would leak easier.As has been said, try to smooth out the inside of the cylinder with some very fine wet and dry paper, maybe stick some new O-rings in and see how you go Also, can you see where the water is leaking from? Is it actualy the lever?Adam Quote Link to comment Share on other sites More sharing options...
nrees16 Posted September 16, 2008 Author Report Share Posted September 16, 2008 cheers for all the info guys, i took the brake to my local bike shop and had it rebled with mineral oil and there was a hell of a lot of air stuck in the master cylinder somehow,now the problem seems to have dissapeared. as for swapping it for an 04 maggie, not a chance lol but thanks for the offer.
