I have (in my opinion) kind of a specific problem. I bled the brakes, but what happened was: the lever on the front brake felt right when pumping... But after squeezing it and holding it for a few seconds, the lever resistance faded and the lever went as far as to the bars with almost no resistance... this was sometimes accompained by a little bit of brake fluid coming out of the breathing hole on the reservoir.. After releasing the lever and pumping it, it felt right again.
I thought that it had to be the fluid passing the master cylinder seal in the reservoir after constant pressure applied...
I had no choice but to look inside the master cylinder if everything was right... seemed so, apart from a spacer that was holding the cylinder inside and being held in position by a "stop ring".. it was bent outwards (I guess it migh habe been from a crash), so I straightened it with a hammer and reassembled the brake. this had set the master cylinder a little bit more inward, b/c the bent spacer allowed the cylinder and the "rod" that's pushing it to come out more.
From what I expected, the lever travel shortened, the lever feel became a little harder, but I'm still experiencing the effect of the lever coming to the bars after squeezing it for a longer time.. as if the fluid would still pass the seal of the master cylinder into the reservoir... (but now it's not "as" bad)...
What would you recommend to do? Should I try to change the seals even if they seemed undamaged? (the brakes are almost new, but I did not get them from an official dealer)
