Is it just me or does this statement make no sense to anyone else? Why would you put the bleeder at the bottom when any trapped air in the caliper would be floating up toward the top of the chamber, where it can not be expelled? I bleed lots of disc brakes in my line of work and you always go for the uppermost bleed screw to allow the bubbles to leave the unit.
