Hi folks, never thought I would be asking this, but I can't seem to bleed my brakes now. I over used my ten bolt rear end so I picked up a 14 bolt. Got it in, hooked everything up, bought a new master cylinder for a C30, bench bled it and now I just cannot bleed the rear brakes. Took the bleeder screw all the way out and nothing. I have never had a problem bleeding brakes before this. Pedal down, finger off bleeder, finger on bleeder pedal up, repeat etc. What am I missing here?
