  • Patent number: 8631911
    Abstract: A drum brake for motor vehicles is described, comprising a hydraulically actuable service brake and a parking brake that is actuable mechanically by means of a Bowden cable, wherein a lasting initial tension of the Bowden cable is to be ensured. For the initial assembly, a retaining plate interlocks the hand brake lever with the web plate of the secondary shoe against the force of the resetting spring. After assembly of the Bowden cable and adjustment of the initial tension of the hand brake cable the interlock is cancelled by pulling powerfully on the hand brake stem. If over the years the hand brake cable stretches, a design-determined initial tension is constantly maintained by the continuous force of the resetting spring.

  • Patent number: 8634999
    Abstract: A method for starting a motor vehicle on a downhill route from an idle state includes the steps of maintaining a sufficient brake force to hold the motor vehicle in the idle state, even if brake actuation by the driver is withdrawn; detecting a wish by the driver to drive off; reducing, independently of the driver, the brake force which is maintained independently of the driver, in such a way that the resulting movement of the motor vehicle follows a preset course.
