If your Mercedes-Benz vehicle has a drum brake system, it's important that you know what parts are involved in its operation, and how they work together. That way you're able to spot any signs of trouble early, before they magnify and put your safety at risk.

The Parts of a Drum Brake System

Some parts of a disc brake system are the same as found with a disc brake system, such as the master brake cylinder, brake hose, and brake lines. Then there are system-specific components like the titular brake drums, brake shoes, wheel cylinders, and assorted bits of hardware.

how Brake Drums Work

It all starts with you pressing your foot against the brake pedal. That causes the master brake cylinder to send hydraulic brake fluid through the hoses and lines to pistons that are located at each wheel. The pistons respond to the pressure of the fluid by pressing the brake shoes against the brake drum. That generates the friction that slows -- and eventually stops -- the rotation of your wheels.
