ABSTRACT:
A method of manufacturing a push rod (10) for a brake booster. The push rod (10) has a stem (12) connected to a head (14). Head (14) is formed from a blank (30) by first machining an axial cavity (36) in an end 34 in a cylindrical body and then fine blanking an axial projection (46) on the other end (32). Thereafter, the depth of the cavity (36) is finalized and an opening (52) drilled along the central axis of the blank (30) to produce the head (14). On insertion of the stem (12) in the opening (52) the push rod (10) is produced.
