Abstract

The proposal is for an improved expansion device for a drum brake having an integrated readjustment unit having a readjusting screw which can be locked therein by a spring-loaded latching unit which, for a reliable readjustment function with a reduced level of force, provides for the latching unit to allow a defined idle rotation of the readjusting screw, which is defined structurally by a first stop acting in a first direction of revolution and a second stop acting in the opposite direction of revolution.
