On the brakes, shaking what is the case, if it is high speed (80 feet or more) on the brakes, steering wheel slight vibration is normal, because there are road resistance coefficient influence and body deceleration impact.
But usually the brake pedal in the 60 step around slowly, first from the pedal pedal force increased with outgoing jitter, steering wheel also began to swing, to measure the brake disc runout, if the edge of the disk runout, but runout flange is normal, it should change on the brake disc OK
If the flange is beating too much, the elevation bearings, flanges, and brake discs need to be replaced together. Because at this time the brake disc will be partial wear deformation. If the brakes are shaking, then check the direction of the ball and dry the ball and the next arm, the ball head is open.
