Front Brakes Building Pressure
08 ZX6R, front brakes building pressure on their own. I just finished this restoration. When I got it, the front brake master cylinder was seized up. (Calipers were not) I cleaned and flushed the whole system. Over a week of sitting on stands, the system would build pressure and Lock the front wheel. I’d bleed it and it would be fine. So I rebuilt the master cylinder with all new internals. It would still build pressure but nowhere near as fast or bad. (Maybe 3 weeks but could still move the front wheel) I bled the system last night. I just took it for its first test ride and after about a mile it completely locked the front brakes. I had to open the bleeder to get it back home. What is causing this?
