Can Servo Brick drive small DC motors via PWM?

I need to drive 4 small traction motors of this 4WD robot platform. It seems like the Servo Brick has a customizable PWM output - can the output be used to directly drive these motors or do I need the DC brick for it (=multiple DC Bricks)?

    The PWM of the Servo Brick can only supply a few mA, you can't use it to drive a DC Motor. With a servo motor you supply 5V to the Servo and then use the PWM to control it. The PWM signals don't need any power.
