* Chevrolet Parts Catalogs (1964): This is the ideal source. You can try to find a reproduction catalog online through sites selling classic car parts or restoration manuals. These catalogs often have exploded diagrams showing every component of the brakes.
* Online Parts Retailers (e.g., Classic Parts, NPD, LMC Truck): Many online retailers specializing in classic Chevy parts have online catalogs. Search their sites for parts related to your truck's rear brakes (e.g., "1964 Chevy C10 rear brake shoes," "1964 Chevy C10 wheel cylinder"). The parts diagrams on their websites are often very helpful, even if not as comprehensive as a full factory manual.
* Repair Manuals (Haynes, Chilton): While Haynes and Chilton manuals might not have an exploded view like a parts catalog, they often include diagrams showing the brake assembly's main components and their relationships. Search for a manual specifically for a 1964 Chevy pickup.
* Online Forums (e.g., Chevrolet forums, classic truck forums): Search forums dedicated to classic Chevrolets or trucks. Someone may have already posted a diagram or can point you to a good resource. Be sure to specify your truck's model (e.g., C10, C20) as that will affect the specifics of the braking system.
Important Note: When searching, be very specific with your search terms. Include the year (1964), make (Chevrolet), model (e.g., C10, C20, C30), and the phrase "rear brake assembly" or "rear drum brakes" (assuming drum brakes). Using these precise search terms will significantly improve your chances of finding relevant diagrams.
