YOu need to "charge" them- attatch a syringe with mineral oil in to the bleed nipple, undo the blled nipple and really force the syringe plunger. While you're doing that, shut the nipple and your brakes will now have less lever throw.
You don't need to take off the lever cap to do this.
With advice like, I really hope that you aren't actually a bike shop like your name suggests.
Why would that cause a problem? surely all it is doing is forcing a little more fluid in thus pushing the pistons out slightly? Got to be far less pressure than pulling the brake lever hard as the hose would blow off the syringe before getting too much pressure in there
