bryanhes Posted October 1 Posted October 1 (edited) The linked braking system is new to me but I believe I have either a faulty rear master cylinder issue or air in the system. When coming to a stop the rear brake slowly drops down and provides no stopping power. I can grab the front and it works fine. I also can let my foot off the pedal and reapply and it will work. Any one of those more prevalent then the other? Either way I will flush the system and see if that fixes the issue. I have a mighty vac so that will make pretty quick work. I'll crack open the manual for proper procedure. Edited October 1 by bryanhes Quote
Zero Knievel Posted October 1 Posted October 1 Bad fluid would be a factor, but if the braking gets worse with use, maybe you have a bad seal letting fluid go back into the reservoir rather than maintain pressure, but I wouldn’t know how to test for that other than apply the brake up on the center stand and see if it travels over time instead of maintaining position.

Lol, from what I have read I could pull new fluid through most of the system to speed up that part of the job then bleed out the remaining air the traditional way, pump up the rear brake pedal then front brake lever then release the bleeder valve until all air is purged as you would most any other bleed job. Is that not correct? I do have the manual but have not cracked it open. Working on 3 different projects currently 🤔 Quote
SwampNut Posted October 2 Posted October 2 I'm not saying it's rocket surgery, but it's long and annoying for parts of it. For example the front lower fork "master" to the rear caliper was not working with vacuum for me, it pulled in air. So I ended up using a trigger clamp to compress it, release it, compress, etc, while Moriah did the open/close on the nipple in back. Quote

I can only assume these are some of the reasons people unlink the system. Quote
SwampNut Posted October 2 Posted October 2 Maybe, dunno. I have yet to ride a delinked bike that I liked. Quote
