If there were no other sources of resistance then what Keith Williams has said would be totally true. However, on a normal landing, there are a number of other forces that will come into play..Rolling resistance, Reverse Thrust/Pitch, Aerodynamic resistance and of course good old brakes.
By delaying application of the brakes, or by using them in a gentle fashion you will increase the effective time that the other stopping methods have to reduce the kinetic energy of the aircraft. i.e. Reverse will take out a bit of energy, etc and this will lower the energy requirements of the brake units, i.e. let them produce less heat. I suppose taking this to the limit by using no brakes at all, and just reverse/aerodynamic braking the roll out will be longer, but your brake temp rise will be nil.
