Beat me to it! The difference with the old Dunlop calipers used on 1960s Jaguars, etc., is that they gave a positive pad pull-back whereas modern calipers just release the pressure from the pads. Very little difference in real life, though, so the extra complication wasn't worth it - & the pads were a swine to make!
