I have bled plenty of Hayes Mags brakes. Face the lever bleed screw up (remove), install a fluid filled syringe on the caliper bleed screw (open) fill till you purge the air. Side note bleed w/ new pads or pistons retracted or face a possible overfill. I am sure the Avids will take the same procedure but their procedure involves two syringes, isloating the caliper from the lever etc. How have you bled your Avids ? Thanx
