GM / Delco Moraine 5450993 – P‑12000 is a factory Delco wheel‑cylinder cup set, not a full rebuild kit. It contains two rubber cups and was used across multiple early‑1950s GM brake systems. These “P‑series” cup sets were sold as economical service parts when only the rubber sealing cups needed replacement rather than the full spring/boot/piston assembly.
