When the brakes are activated, brake fluid acts on the wheel cylinder, which pushes the brake shoes outward against the rotating drum and creates friction. The wheel and tire assembly then slows down and the brake hardware holds the shoes in place.<\/li><li>Disc brakes create friction with a disc-shaped rotor and a pair of brake pads. When the brakes are activated, the brake fluid acts instead on the brake caliper, which squeezes the brake pads against the rotor, creating friction. Because the rotor is bolted to the wheel, the wheel and tire assembly starts to slow down.<\/li><\/ul>\n<\/div><\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n\n\n<p>Does your car have drum brakes, disc brakes&mdash;or both?

Some vehicles use disc brakes to get the job done, while others use drum brakes. There are also some applications that have discs in the front and drums in the rear.<\/p>\n\n\n\n<p>The primary difference between disc brakes and drum brakes is relatively straightforward. Disc brakes create friction with a disc-shaped rotor and a pair of brake pads, whereas drum brakes use a circular drum and brake shoes.<\/p>\n\n\n\n<p>Of course, there&rsquo;s a bit more to it than that. Each brake drum or disc brake assembly contains a unique collection of parts that work together to stop the vehicle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are Drum Brakes and How Do They Work?<\/h3>\n\n\n\n<p>Many vehicles have a drum brake assembly behind each of the rear wheels. There are also some classic cars with drum brakes at all four corners.<\/p>\n\n\n\n<p>Each of the circular drums fits over the top of a set of brake shoes, associated hardware, and a wheel cylinder. One of the car&rsquo;s wheel and tire assemblies is held against the brake drum with a set of lug nuts.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake-1024x1024.jpg\" alt=\"parts of a drum brake illustration\" class=\"wp-image-24187\" width=\"1024\" height=\"1024\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake-1024x1024.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake-300x300.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake-768x768.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake-75x75.jpg 75w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake-600x600.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake-928x928.jpg 928w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake-150x150.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/03\/parts-of-a-drum-brake.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Although some vehicles still have drum brakes in the rear, the technology is being phased out because disc brakes are far superior.<\/figcaption><\/figure>\n\n\n\n<p>An individual drum brake operates as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>When the driver activates the brakes, fluid from the master cylinder acts on the wheel cylinder.<\/li><li>The wheel cylinder then pushes the brake shoes outward against the rotating drum, creating friction.<\/li><li>Because the drum is bolted to the wheel, the wheel and tire assembly starts to slow down.<\/li><li>The brake hardware holds the shoes in place and maintains the correct shoe-to-drum alignment during braking.<\/li><\/ul>\n\n\n\n<p>Although some vehicles still have drum brakes in the rear, the technology is being phased out because disc brakes are far superior.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Are Disc Brakes and How Do They Work?<\/h3>\n\n\n\n<p>All modern vehicles have a disc brake assembly behind each of the front wheels.
