Making rotors larger just increases the mass of metal able to be used as a heat sink. Breaking force remains the same but maximum braking force can be maintained for longer before the brake temperature exceeds the maximum operating temperature of the system.
Bikes have large diameter but very thin rotors to maximise the heat sink available for the least weight, possibly for looks and brake lever feel as well.

WTF!!!
oh dear god... go read an elementary physics book, speciiclly the chapter titled "torque"
i am astounded you can state all of the above with a straight face. please dont continue to spread misinformation...
and fwiw: bikes weigh oh, i dunno, 15% the mass of a car?? they only have x amount of kinetic energy to scrub off, and thus dont need 32mm thick rotors to act as heat sinks.
lever feel is SOLEY a mechanism of slave/master ratio, lever design, hose flexibility, and caliper flex.
i didnt want to get into explaining this, but i guess i should...braking force is governed ONLY by pad frictional force (which is influenced by piston force, and pad compund only - NOT surface area), and rotor diameter. other factors like pad surface area, rotor slotting and drilling, rotor width etc are to do with heat and gas control.
obviously then, the two best things to upgrade are pad compund, and rotor diameter. dia is NOT a heat thing... yeash!
