Is the force needed to use automobile brakes the same as using an airplane rudder

Answer 1

No. One decelerates; the other changes direction.

Answer 2

Do you mean how hard you have to push the pedal? If so, it's hard to say. Cars may or may not have power brakes, airplanes may or may not have something similar. I'd think it also depends on how fast the plane is going, and crosswinds, etc.
