Drum brakes are a common type of braking system found in automobiles and other vehicles. They work by pressing brake shoes against the inside of a spinning drum to slow down or stop the vehicle. However, there are many different terms used to refer to these brakes, including "drum brakes", "shoe brakes", "wheel brakes", and "internal expanding brakes". Each term describes the same basic mechanism of braking, but may be used in different contexts or by different manufacturers. Understanding the various names for drum brakes can help drivers and mechanics communicate more effectively and ensure that the proper replacement parts are used when necessary.
