Captain Scarlet Posted January 5, 2007 Report Share Posted January 5, 2007 Hey guys,I just got my Hs33's in the post today was gonna slap them on now, but I'd rather do a job properly and think about it first.Both brakes come with full length pipes, so I obviously need to shorten at least one of them.The manual goes over it, but not in too much detail about what not to to, and what to ensure happens.Is there a good way of shortening one of the cables without the risk of fluid spilling out?, what is the best method for shortening the pipe whilst keep the fluid in the pipe?It also goes on about putting Heatshrink tubing on the pipe after cutting it before putting the olive on?, what is the need in the Heatshrink tubing?Any other matters regarding this that you guys think I should know about, or suggestions to fitting the brakes, then please fire away.Thanks in advance, Quote Link to comment Share on other sites More sharing options...
ted Posted January 5, 2007 Report Share Posted January 5, 2007 This video should tell you all there is to know about cutting/re-attaching magura hoses:>> LINK << Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted January 5, 2007 Author Report Share Posted January 5, 2007 Nice link but it doesn't answer my question.I want to know, why use Heatshrink piping? and an effective way of shortening the brake line whilst keeping the fluid in the line?Thanks Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted January 6, 2007 Author Report Share Posted January 6, 2007 So nobody knows how to cut a Hs33 pipe effectively without having to re-bleed? Quote Link to comment Share on other sites More sharing options...
kid creole Posted January 6, 2007 Report Share Posted January 6, 2007 you cant cut it and still keep the oil in it you just have to rebleed it afterwards Quote Link to comment Share on other sites More sharing options...
Broomer Posted January 6, 2007 Report Share Posted January 6, 2007 you cant cut it and still keep the oil in it you just have to rebleed it afterwardsas long as you make sure you top up the oil in the lever and the hose you shouldnt need to rebleed.

kid creole Posted January 6, 2007 Report Share Posted January 6, 2007 as long as you make sure you top up the oil in the lever and the hose you shouldnt need to rebleed.yeah but surely as soon as you cut it air will get in the system ?

26inch Posted January 6, 2007 Report Share Posted January 6, 2007 Fully loosen the tpaJust undo the shroud nut and slide it down the hose then remove the olive.Carefully cut the hosedown to a suitable lenth with a sharp object, make sure the cut is at a rightangle.Be very careful not to loose any fluidPut a new olive on (some spares should come in the box)Put a dab of fluid on the end of the hose (use the fluid from the cut off section)carefully slide back into lever body and tighten shround nut.Ive done this loads of times without needing a re bleed. And i dont know why they have spoken about shrinkwrap. That method^ works though Quote Link to comment Share on other sites More sharing options...
moza Posted January 6, 2007 Report Share Posted January 6, 2007 i would ignore the bit about the heatshrink. i realy dont understand what you would need it for. just go ahead and shorten it.moza Quote Link to comment Share on other sites More sharing options...
Simpson Posted January 6, 2007 Report Share Posted January 6, 2007 Ive done this loads of times without needing a re bleed. And i dont know why they have spoken about shrinkwrap. That method^ works thoughto be honest for the ammount of time and effort its going to take to ensure that no air gets into the system, it will be a lot quicker just to cut it shop it and re-bleed it.... surley its going to feel nicer that way if you want your maggie done all propperly before putting it on your bike.....id do it anyway why go to all this effort fit it just to find out half your tubes air? might as well just bleed it well afterwards Quote Link to comment Share on other sites More sharing options...
Captain Scarlet Posted January 6, 2007 Author Report Share Posted January 6, 2007 Well I tried and failed.When setting the TPA to low pressure, my dad suggested taking the lever blade out so there is no pressure at all.But the piston in the Master cylinder popped out and I lost a bit of fluid. So I've just taken it down to autoparts for them bleed the brake for me.Back one is fine I got that one all set-up and working perfectly, its just because of the fact that I had to trim the front brake.

trials_mad Posted January 6, 2007 Report Share Posted January 6, 2007 I thought I might just add..... It's worth getting to know how your magura works and having a play with it because the knowledge will be invaluable later on. Quote Link to comment Share on other sites More sharing options...

You need pressure in there... or at least a seal, so that when you take the cable off the lever all the fluid stays inside the lever due to the vacuum.You really should have bled it yourself, its not difficult in the slightest. And if you didn't have proper magura oil, vegatable oil would have worked. Quote Link to comment Share on other sites More sharing options...
