I just recieved a front Juicy Seven. It's been used but it's on a fresh bleed and fresh pads. Before I mounted the brakes the red knob (pad contact width) worked fine but after I mounted it, it seems excrutiatingly hard to turn towards the "out" direction. There is way too much space in between the pads right now and I gotta squeeze all the way down. Any help on how to reduce the pad width space? Thanks!
