Here’s the lowdown on mechanical drum brakes circa 1934, courtesy of the Chevrolet Motor Division. Great little movie, check it out.
This little 10-minute instructional reel doesn’t require a lot of explanation. Produced by the Jam Handy Organization, the film was designed to showcase the operation of the brake system on Chevrolet’s 1934 passenger cars. And if you ever wanted to learn how these early mechanical drum setups worked (pretty well, actually, all things considered) here’s your video. The technical insights offered here are excellent.
Of course, we also watch these old films for their their wonderful little glimpses into everyday life in the past—their time machine properties. In that regard, the film is also a gem. Enjoy.
