1989 k-1500 brake question

1989 chevrolet k-1500 4x4 with 4.3L engine. During brake application the vehicle "hops" or feels like its bouncing up and down slightly. I'm guessing the rotors/drums might need replaced to fix this. any
other suggestions as to what this could be?

You might also check your shocks, front drive shafts, steering parts, front bushings, and hubs. But your first guess is mostly right, a out of round drum or warped rotor.
