Thanks for the reply, I have been doing brakes for a long time and never ran across this. Today I just pressure bled it twice following the factory sequence. I have to believe its hydraulic but darn if I can figure it out. Ready to tow it to the local shop.VStar650CL wrote: ↑Sun Oct 10, 2021 8:34 amYou must have air in there someplace. If it kept going to the floor but more slowly after being pumped, then it might be torn seals in the master. Since it holds firm, you're definitely compressing some trapped airspace. Try re-bleeding the system from the top down, start at the master and work down to the wheels.
