If you feel it in the brake pedal, that is usually and indication that there is a thickness variation in the rotor or a rear rotor/drum is out of round.
A good test for the rear drum is to drive about 10mph and slowly apply the parking brake until the shoes contact the drum..if you feel your vibration, then I would look towards the rear drums as the cause.
