i dont no if anyone has put this yet... but i wind the tpa on untill the pads move as soon as i touch the lever. undo the bleed bolt on the lever,put syringe and tube on. put pressure on the syringe and wind the tpa out. ( torwards the minus) this draws the piston back and at the same time you are filling it up with water. ( the air escapes past the bleed tube) when the tpa is all the way out take off bleed tube. insert grub screw... hey presto! if you want to overbleed then just push harder on the syringe.. sorted. courtesy of prawny.
