Abstract: The brake caliper unit has two caliper levers whose one ends are linked to brake pads and whose other ends are linked to a slack adjusting device extending between them. The central regions of the caliper levers are coupled to a housing, in which case the coupling point of one caliper lever is constructed as a simple rotary bearing. The coupling point of the other caliper lever is constructed as an eccentric transmission which can be operated by a brake cylinder held in the housing by a crank arm in the direction of the approach of the two caliper levers. The eccentric transmission has a shaft which is rotatable in the housing about an axis and which, with an eccentricity directed diagonally away from the brake disc carries a pin with the axis on which the caliper lever is disposed. The eccentric transmission permits a high power transmission ratio with relatively short caliper levers.
