A wedge brake unit has two brake applying members (2, 8, 10, 3, 9, 11) and a synchronizing shaft (17-19) rotatively connecting these two members for accomplishing synchronizing of a wear compensating rotation at both members. A wear indicator for indicating wear of brake linings connected to the brake applying members includes a sensor in the form of a magnet (23) on the synchronizing shaft and a stationary electronic switch (25) to provide an electric counting signal indicative for the rotation of the shaft and thus for the lining wear. |
