Drum brakes were the standard braking system used in classic cars before the advent of disc brakes. They were simple in design, consisting of a drum-shaped brake housing and brake shoes that pressed against the drum to slow down the car. While they were effective at stopping the car, they did have some downsides. One of the main issues was that they were prone to overheating and fading during prolonged use, such as during long downhill descents (via Car & Driver).
Additionally, they required more maintenance than modern disc brakes, with regular adjustments and occasional drum resurfacing needed to keep them working properly. Despite these drawbacks, many classic car enthusiasts still prefer drum brakes for their authenticity and period correctness. They offer a unique driving experience that can’t be replicated by more modern braking systems.
