yeah , this method has never let me down, I push water through with the syringe first, then suck it back through the other way. on my Ashton I did use an evo 2 mount, which is effectively a 4 bolt booster behind with a 2 bolt one on top. not running a booster on the inspired, and my brake is amazing, and solid. got heatsink red pads in tnn backings now
