What kind of brake does a GM FWD vehicle use?

A prime example of this are GM FWD vehicles that are equipped with duo-servo rear drum brakes. Most FWD vehicles use a non-servo rear drum brake because of the braking balance of a FWD vehicle. These GM vehicles are “over-braked” in the rear which makes them very sensitive to rear brake problems.
