I am trying to understand why a bigger swept area on disc brakes provides higher braking force for the same force being exerted on the brake lever/pedal by the rider.
If we use the same exact brake pad material, same thickness, same disc material/surface treatment etc. and the only variable we change is the width of the brake pads and therefore increase the swept area, would this result in higher braking force for the same lever/pedal input force? If so, please explain why.
Larger swept area means better cooling of the pads during braking but that shouldn't make a difference when the brakes are still cold. Larger swept area also means the pad material can be softer since the brake pads are larger so won't wear as quickly as the smaller variety, is this a significant reason why larger swept are provides better braking performance?
Would increasing the length of the pads (thus not increasing swept area) also increase braking performance (braking force higher for same lever/pedal force)? If so, would it have the same effect as making the pads wider?

Thank you for any input, it is greatly appreciated!
