I'm think I'm going to go insane trying to bleed the brakes on my damn bike. I rebuilt the front brake caliper, and the master cylinder seems to be OK. For the life of me I can't get the damn thing to build any pressure. I thought I was on the right track for a while, but now when I pump the lever and crack the valve, no air is coming out, just fluid - and the resivore doesn't seem to be losing any fluid. I think I may have some air in the brake lines or in the caliper. Any tips would be greatly appreciated, I think I'm going to go insane
