Nick Garland Posted December 25, 2006 Report Share Posted December 25, 2006 Hey, Ive just bled my brake about 5/6 times, The piston that is connected to the lever does not move much, yet the piston connected to the other piston moves fine. I have grabbed the pistons both with pliers and they both move smoothly. Any idea how to fix this. Quote Link to comment Share on other sites More sharing options...
Walleee Posted December 25, 2006 Report Share Posted December 25, 2006 (edited) What's the problem?When the brake's are on the bike the one that moves easy will hti the rim, and then the other will follow hitting just afterwards....

Ross McArthur Posted December 25, 2006 Report Share Posted December 25, 2006 yea sometimes that happens man, itll be fine when you ride it it wont be noticed. Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted December 25, 2006 Author Report Share Posted December 25, 2006 No not quite. Before I had standard magura with black hosing etc and it did as you described, normally though its the primary piston that moves first then the slave.I class primary as the one with 2 hoses, ie connected to the lever and to the other piston.However this is the piston that is NOT moving at all and the slave piston as I refer to it is moving properly.If you follow me. If not I can go video it. Quote Link to comment Share on other sites More sharing options...

Nick Garland Posted December 25, 2006 Author Report Share Posted December 25, 2006 Ive bled it 6 times as I said, its on the bike now, it works as I have one pad really close so kinda rubs but I can ride Cant do the link above as I have no bleed kit, I did this in the sink. Spose I shall buy a bleed kit and give that a go. Quote Link to comment Share on other sites More sharing options...
matt! Posted December 25, 2006 Report Share Posted December 25, 2006 new cylinder then or new magura..better option.. Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted December 25, 2006 Author Report Share Posted December 25, 2006 Think it might have to be new magura, then just fit the braided hosing, and new lever blade onto it , pain in the arse. Quote Link to comment Share on other sites More sharing options...
Walleee Posted December 25, 2006 Report Share Posted December 25, 2006 stop messing about with them and ride? Honestly, tinkering with magura's is the worst thing you can do. Fit and Forget. Quote Link to comment Share on other sites More sharing options...
squince Posted December 25, 2006 Report Share Posted December 25, 2006 Its the braided hosing, lose the hosing. Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted December 25, 2006 Author Report Share Posted December 25, 2006 A little impossible to fit a magura with split hosing and ride Thus I ordered braided hosing which I fitted bled and it did not work, and I am riding with it as it is, not too bad just abit slippy .

squince Posted December 26, 2006 Report Share Posted December 26, 2006 Should have fixed it with the standard magura tubing. Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted December 26, 2006 Author Report Share Posted December 26, 2006 (edited) Sorted it.Took it all apart, managed to bodge up a device to pump out crap from all pistons etc. Re-bled, still didnt work, so I went out to my shed, and I found a spare master slave cylinder, yellow so doesnt go with bike well but oh well. Bled this up and it works, the primary slave cylinder works as it should, fast and responsive, first to move, the secondardy slave moves as expected, abit lagged.I think I just had a dodgy slave cylinder.

Lee Cable Posted December 26, 2006 Report Share Posted December 26, 2006 Get a V brake Quote Link to comment Share on other sites More sharing options...
JT! Posted December 26, 2006 Report Share Posted December 26, 2006 (edited) Get a V brakeStfu.Here's what's i do's...One of the main problems to occur with maguras is known as a ‘lazy piston’. This means that only one of the pads seems to move, and one pad seems to just sit up against the rim just skimming it. The reason for this is because you have too much TPA. If you undo your TPA right off, you will see both pads retract normally. If you do have a lazy piston, you need to re-setup your brake like instructed in the next paragraph.The better you set up your maguras, the better they will work. If your re-setting your maguras up, undo the bolts on the clamps and remove the brake completely, make sure the large plastic washer are all intact, if they’re chewed up, it can cause problems later on.The next thing you need to do is undo your tpa right out. This is important especially if your having lazy piston troubles. You need to undo your tpa so that the pads retract right back. You know when you have reached this point when you can pull the leaver down and it isn’t actually pushing an fluid though, this is because the pads can not physically more any further back. Now is a good time to double check you wheel is straight (if you have horizontal dropouts anyway). What some people do (including myself) is realign the wheel rather than adjusting the maguras. After doing this a few times your wheel can be at any weird and wonderful angle without you noticing.Now, to put the brake back on. Do one side at a time. First, place the underside of the clamp down. The place once side of the Magura on top of it, but have the brake pad pushed right up against the rim. The reason for doing it like this is that it’s easier to move the brakes out, than move them back in. Also, it gets it in a good initial position. After you’ve done that, place the top part of the clamp on, and screw it down. When screwing the bolts in, try and screw them in evenly. If you screw one side right down, and then the other, your putting a lot of extra strain on the other bolt, which isn’t good where threads are concerned and how easy they strip.Screw them down so it holds the cylinder firm, but so you can still move it about. Then you simply wiggle the cylinder back, you can actually pull the leaver to help move the cylinder back if you need to. A good guide to how far you need to pull it back is that you should just be able to put a 2p coin between the brake pad, and the rim. Once you have got it the right distance back, rotate the cylinder round so all of the pad will hit the rim, and that the surface of the pad will sit flat on the rim. Once you have it perfect, slowly tighten the bolts up, remembering to tighten them up evenly. Keep your eye on the position of the pad, and make sure it stays in the position you’ve just set it up in. Tighten the bolts down firmly, but be careful you don’t go over the top, it can damage the threads in the frame.Now that you’ve done one side, do the same for the other side.Now all you need to do is adjust the tpa to how you like it and there you go. It is difficult to do first time, but the more you do it the easier it will become. There are a lot of different techniques to setting up your brake, so if you find a way that suits you better, stick with it. Edited December 26, 2006 by JT!

Jonny Jones Posted December 26, 2006 Report Share Posted December 26, 2006 (edited) I thought both pistons were meant to move together? Mine do. I have Magura Braided hosing too, love it. I also bleed my brakes with Magura Royal Blood, well, its just Magura Blood now I think, they lost the whole Royal thing... anyway, yeah mine both move together, great braking power and the pistons come out and retract really fast too, so its a nice feel and everything. Consider using oil, that said, once bled with evil H2o, it messes up the internals so as soon as you put oil back in, the system goes a bit Pete Tongue... this is in my experience, though. Glad you got it sorted, you could just spray the Raceline cylinder? Although I'd give anything to own a new pair of Racelines Jonny.

Nick Garland Posted December 26, 2006 Author Report Share Posted December 26, 2006 Ha yea its sorted. If it lasts till the end of summer will be fine as its an 05 in all fairness, will give me an excuse to get a new one Mate has had his with water for about 4/5 months now, its lush as. Not sure how royal blood feels compared to water. Quote Link to comment Share on other sites More sharing options...
