ABSTRACT:
A method of producing pneumatic brake actuator rods in which a spigot is provided at one end for mounting a pressure plate and a thread is provided on the output end, the body of the rod around the root of the spigot being under cut and thereafter upset by roll-swaging or other means to produce a flange for supporting the rod against the pressure plate so that the rod can be of generally substantially reduced diameter in relation to that used for many years hitherto.
