Brake Problems

Usually having to pump brake, is the first pump is moving something, the second pump applies pressure.
It's usually the rear brake adjustment, the first pump moves the wheel cyls/pushrods/shoes out to the drum, second pump applies pressure.
The front pads, if installed correctly, won't have movement as such cuz they just relax, no spring return.
We're I you, I'd adjust the rear brakes first, just checking all wheel cyl pushrods are in proper position on the shoes, that should get rid of the need to pump.
Master/cyl bore size, and proper bleeding can also affect pedal "feel".
