I have been trying to bleed this set of brakes for about a week now. I cannot get fluid past the brake lever. It feel like there is a ton of back pressure and will blown the hose off the syringe if I press to hard. I finally rebuilt the lever and I’m still in the same situation. move tried pushing fluid in from the caliper side and it’s the same issue. I ran fluid through the bleed port on the lever after unscrewing the pad in knob and it fills fine, but with that knob on, the fluid won’t go in. Any ideas?
