Brake Shoe: Description and Operation
Brake Drum Assembly
DUO-SERVO BRAKES
The anchor plate drum brakes are called duo-servo design. In the duo-servo drum brake, the force that the wheel cylinder applies to the primary
shoe is multiplied by the primary lining friction to provide a very high force applied to the secondary shoe.
Torque from the brake shoes is transferred to the anchor pin and through the backing plate, to the axle flange. Adjustment is automatic when the
brakes are applied while the car is backing up.
