I have Hayes 9 XC brakes and after a nasty spill the front brake lost pressure. After not seeing any fluid leaking from the system, or near the spot of the crash, and not seeing any visible signs of breakage or failure I was stumped.
I bought a bleed kit and attempted to bleed the front brake. I followed the directions, but I noticed that everytime I manipulated the lever more air bubbles would appear. When I thought they were all gone I closed the system but it would never build pressure.
I checked what I was doing by bleeding the rear brake. Sure enough, I had no troubles and the rear brake worked fine.
I'm left to wonder if during that crash the bike came down on the front brake lever possibly damaging something on the inside. Again, there's nothing damaged as far as I can tell from the outside. Is it possible for the lever/plunger to be damaged and let the smallest amount of air in without letting out fluid? Is the problem elsewhere?
I need help!
