Abstract
A rail vehicle brake actuator (1) has a brake block holder (4) suspended therefrom so as to be laterally movable during braking. Upper ends of brake block hangers (5) are attached to brackets (2) on the actuator (1) by a joint (15) allowing relative laterally pivotable and rotatable movements of lower ends of the brake block hangers to the brake block holder. The lower ends of the brake block hangers (5) are laterally pivotally attached to a movable brake block holder axle (16) extending through a transverse bore in the brake block holder (4), and spring mechanisms (21) are arranged to act between the respective brake block hangers and the brake block holder.
