ABSTRACT:
Brake force is transmitted between a single axially movable push rod (6) and a brake block holder (3) by an intermediate force transmission member (22) to accommodate for movements along the wheel axis. This intermediate member (22) has cylindrical surfaces cooperating with both the block holder and the push rod end. The cylindrical surface (22') of the member (22), which cooperates with the brake block holder portion (21), is arcuate with its circle center coinciding with the center for the cylindrical push rod end (6'). A shackle (24) held on the brake block holder is biassed by springs (28) forward toward a brake application direction to retain and frictionally engage protrusions (23) extending from the actuator push rod (6).
