Installing & Bleeding The New Aniioki A9 Pro Max Brakes! 🛠️ | Full CBS Upgrade (Part 2)

We are back with Part 2 of the full brake system overhaul on the Aniioki A9 Pro Max! If you watched Part 1, you saw me completely tear down the old, locked-up system. Today, we are installing the brand-new upgrade kit straight from Aniioki. This video covers the most critical parts of the job—especially dealing with those massive new thick cables and swapping out the central Combined Braking System (CBS) box (the little red square thing). Mixing old and new parts has been causing a lot of threading issues and fluid leaks for riders in the community, so we are showing you the right way to do a clean, full-system install from scratch. What we're knocking out in this video: Routing the new, thicker hydraulic lines cleanly through the frame. Mounting and plumbing the new dual-front and rear CBS block. Getting a solid thread seal without over-torquing the levers. A complete system bleed using Royal Blue Mineral Oil to get that rock-solid lever response. If your hydraulic levers are feeling mushy or completely locked up, this step-by-step walkthrough will show you exactly how to get your stopping power back safely. Thanks for watching!
