The invention discloses a forming process of a braking hard pipe pier head. The forming process of the braking hard pipe pier head comprises the following steps of blanking to obtain a hard pipe workblank piece; chamfering: chamfering an inner angle and an outer angle of a cross section of the hard pipe workblank piece; forming the pier head, and forming the chamfered hard pipe workblank piece toobtain the pier head. According to the forming process of the braking hard pipe pier head provided by the invention, the inner angle and the outer angle are chamfered on the cross section before forming the pier head, so that the accuracy and the stability of hard pipe fractures before forming the pier head can be improved, the finished product quality of the hard pipe pier head is ensured, the occurrence of the defects of concave pits and indentation is avoided, an oil leakage problem of a braking hard pipe matching part is further solved, and the safety factor of a vehicle is improved.
