The invention relates to a wear adjustment device for a brake, especially a motor vehicle brake. The device comprises an adjusting shaft, which is mounted in a housing and is accessible from the outside at a front end. Said adjusting shaft is equipped with a head part in the accessible area, this head part enabling the transmission of a torque. The head part is configured as a separate structural part and can be coupled to the adjusting shaft in such a way that it is resistant to torsion in the axial direction of the adjusting shaft and in relation to said adjusting shaft. The head part is also provided with a predetermined breaking point which enables separation to take place when a maximum permissible torque is exceeded. This constructionally simple configuration reliably prevents the adjusting shaft from being overburdened and therefore prevents any damage to the wear adjustment device or essential parts of the break that this could otherwise cause. In the event that the head part is destroyed, the destroyed head part can be replaced by a new head part without impairing the brake as a whole. |
