Motors says Bendix had 4 types of brake systems in the prewar years. Hydraulics were Type 1: no eccentric, T-2: 1 eccentric, T-3: two eccentrics, and T-4 was all mechanical.

Prewar Packards from early 30s used mostly T-2 with T-4 used on some senior models. Postwar all used the type 1 which is on your 54 and what most of us are familiar with.

Motors did not mention any operating characteristics or advantages/disadvantages of one system over another and why one type in particular was chosen for use in a car but the shoe positioned eccentrics of T-2 and 3 must not have been that advantageous to be worth the added mfg cost since they eventually went away. Maybe there is someone who knows or is curious and enjoys doing research who could answer that.
