Your brake lines would have to be the exact same length to make everything equal. Are brake lines the exact same length ?
The braking force applied on the pads are equalised on both sides simultaneously
at unitary fluid pressure of a single common feed line.
The unequal pad thickness, if any and typically unequal brake line lengths on both sides do NOT matter under typical braking condition.
Hence, unequal braking force on both sides is a myth under proper brake operating conditions.
I'm refering to hydraulic-related force on the pad/rotor on both sides of a car, which to be specific, is perpendicular to the rotor surfaces.

Three is equal pressure at the piston on each side, fluid dynamics make that invariable barring mechanical impediments with the piston (which do sometimes happen). I agree pad thickness should not matter. But that's not what we are talking about here.
But you are assuming ANY pad will transmit that force equally well. If that were true, there would be no difference in performance from organic, semi-metallic, or ceramic pads. Also, that means there would be no difference between different brands.
Different pads will act, well, differently. Some might bot be noticeable. Some will. Since you already have a pair for each wheel, why gamble?
Are you refering to the same?
Next , did I say ANY pad .... in the context of differing materials and brands ?
