Electro-mechanical Duo-Servo

Electric Drum Brake

The Electric Drum Brake is based on the Duo Servo principle and provides high brake torques for heavy vehicles on rear axle or light vehicles on front axle.

The e-DS is based on the Duo Servo principle and provides high brake torques for heavy vehicles on rear axle or light vehicles on front axle.

Furthermore, the brake comes with a wheel control unit with an integrated torque sensor for precise modulation of each drum brake, providing a maximum of controllability while the brake offers full freedom in its mounting position. Various assistance functions for safety and comfort can also be implemented.

An electric caliper can be used for the front axle of heavy and performance vehicles.

Benefits & Features

  • Very high C* = from heavy duty to downsizing potential with scalable concept
  • No hydraulic fluids = no fill and bleed
  • Plug & play (corner module)
  • Early testability
  • Full-blending capability
  • High corrosion robustness
  • Adaptable brake pedal feeling
  • Service prediction
  • Low drag torque
  • Low corrosion & low Emissions with encapsulated brake design
  • Independent control of braking forces per wheel
