First time SRAM brake user, not a huge fan of the system as I've used Shimano all my life. I replaced both front and rear pads on my G2 system, centered the pads to the rotors, but there is a good amount of drag on both ends. The wheels can barely spin freely. I removed the bleed screws thinking there maybe too much back pressure build up from the new pads, but no go. Any thoughts/suggestions appreciated.
