The only stop is the width of the vertical part of the spreader 
spring. The pad backing plates will run into that at some point. That 
piece is supposed to be slightly wider than the rotor, but spreaders 
vary depending on their origin.

Once the backing plates run into the spreader spring, the pads can 
still hinge inwards, but with much less braking action.
