OK. It just seems weird to me -- the pressure would be different on either side of the rotor -- you would think that would lead to a warped rotor, and cause problems with runout. But then, every car I have ever worked on had multi-piston calipers.
The same force is exerted on both sides. Equal and opposite, there’s only one piston.
And you’re assuming the pad area is different. It might not be, the longer pad might not be as tall. See that a lot. Different shape with the same area.
