Abstract: A support unit includes a first flange portion, a second flange portion and a guiding portion, wherein the first flange portion has a first engagement geometry for securing the support unit to a chassis, wherein the second flange portion has a second engagement geometry for securing a brake cylinder, wherein the guiding portion is arranged adjacent to the second flange portion and has a guiding geometry for guiding a guiding element along a guiding axis, wherein an expansion wedge unit is provided adjacent to the guiding portion and wherein the expansion wedge unit has a housing which is constructed integrally with the guiding portion.

Abstract: This relates to an actuating unit, in particular for a drum brake, comprising a spacer element which can be fixed on a shoe unit or on a supporting unit, the spacer element having a holding section, via which it can be secured against movement along an activating axis relative to the shoe unit or the supporting unit, the spacer element having a first engagement section which is supported on the respective other one of the units comprising the shoe unit or the supporting unit in a first position of the spacer element, it being possible for the spacer element to be moved into a second position, in which the first engagement section is out of engagement with the shoe unit and the supporting unit, the spacer element spacing the shoe unit and the supporting unit further apart from one another in the first position than in the second position.

Abstract: The invention relates to a brake system in particular for wedge-actuated drum brakes, comprising a carrier unit, an actuation unit, a reference unit and an indicator unit, wherein the reference unit shields the carrier unit and the actuation unit at least in regions, wherein the actuation unit engages on the carrier unit and displaces the carrier unit into a particular position relative to the reference unit or secures the carrier unit in one position relative to the reference unit, wherein the carrier unit engages on the indicator unit in order to displace the indicator unit into a particular position relative to the reference unit, wherein a state of wear of the brake system can be determined from outside the brake system by way of the position of the indicator unit relative to a reference geometry provided on the reference unit.
