Often you can hear a vacuum leak at idle, it will be a hiss sound, you can listen with a piece of rubber tube to your ear and the other passing around inlet manifold gaskets and vacuum switches, if there is a leak you will hear it quite clearly, please describe the brake problem with a bit more detail, i don't quite follow what you mean by a little jump.
