The brakes feel great on my coupe, but why when I give the pedal a little pump, the pedal really stiffens up? The braking power is even better.

Sounds like residual air in the line. Try bleeding the brakes or have a shop power bleed them. Also check the flexible brake lines and make sure they're not old and cracked. They will expand (not good) when applying brakes.
