I purchased a replacement pedal a couple of years ago. My original had a piano style hinge at the floor, attached to the floor with a couple of screws. The replacement pedal had no hinge but supposedly depended on the "springiness" of the rubber/thin metal backbone for flexibility. It never even came close to being functional. I called the supplier and, according to them, nobody had reported a problem with it.
I solved the problem by sawing off the bottom portion of the old pedal and then ground off the rubber from the moveable part of the hinge. I likewise ground off the rubber bonded to the lower bottom side of the new pedal and glued the two parts together with gorilla glue. It has been totally satisfactory.
