Brake drum spring

Was looking at brakes on front of Randy's Caribbean saw grove relief machined in outside of drum and reminded me that a lot of GM cars back in day had a coil spring installed (spring looked like the type which were used to close screen doors) on out side of drum was told it was to aid in cooling and stop noise. Just a general question curiosity from my old memory of cars.
