ABSTRACT:
A brake block holder arrangement comprises a brake block holder (7) receiving a brake force from an axially movable push rod (2) of a brake actuator (1) and being pivotally attached to brake block hangers (5), which are suspended from a suspension bracket (4) on the actuator. A push rod head (3) on the push rod is in direct contact with a generally tube-shaped portion of the brake block holder around its shaft (8) for pivotal connection to the hangers. For accomplishing guiding and torque transmission the push rod head has extensions (11, 12) with a width corresponding to the distance between the side-walls (7') of the brake block holder, one of the extensions being provided with a laterally movable cross piece (19) for toothed engagement with rotatable segments (16) in the inner surfaces of the side-walls.
