I’m swapping out the 3T Aduro for a different cockpit on my 2013 P5 and want to keep the Maguras. Is there a way I can disconnect the hoses without having to cut them? RT 6TT Manual and videos on bleeding the brakes aren’t helpful in this regard. Thanks in advance.
You will have to cut a small amount of the hose.
You loose about 1cm, you can cut right at the hose nut.
You can disconnect them from the caliper without cutting. You just need to unscrew the nut that surrounds the brake line as it enters the caliper. This will leave you with an olive compressed onto the end of the line. Whether or not you are able to re-snake the existing hose through your new bars with the olive still on the line… depends on the size of the openings. Likely, you’ll need to cut that olive off - which means sacrificing about 1cm of the end of the line. And you now need two new olives for the new connections. Hope this helps. Good luck.
As others have stated and I would add to back off the adjuster on lever beforehand, disconnect at caliber and then cut.
I do not know if you leave the same olive to be a good idea, there is some plastical deformation involved at installation and Magura advices explicitly to not use an old olive. On the other hand there have been people who reused the hose with the existing olive and it would save you some work…
If you are lucky you can even do the whole operation without bleeding if the fluid stays in the hose through capillary attraction (that’s probably why ktm520 here above remarks to back off the adjusting screw in the lever).
I had to exchange the hose because it went too short after cutting and than I needed to attach the new hose at the lever which is another operation than that with the olive: You need a special plastic counter bearing to put in a bench vice and then to hammer the attachment part into the hose. This is all documented in the Internet though (I guess Magura has that still online) and I managed to do it.
The documentation for bleeding is still online.
(It would be not dum maybe to print the documentation: I haven’t done that yet).
Thanks, all! Will see how it goes.
