What Are Drum Brakes?

Modern braking systems involve a huge number of different components in the vehicle working closely together so you can stop and manoeuvre your vehicle under control. The key components within the vehicle’s braking system are the master cylinder, a servo, brake callipers on each wheel, brake fluid and cylinders, discs, pads, drum brakes and shoes. All the components are linked by hoses and pipes. Read our article in full to find out what drum brakes are…

What Are Drum Brakes?

The master foot brake pedal is linked to the master cylinder. The brake master cylinder is located in the engine compartment of your vehicle. The master cylinder contains hydraulic brake fluid. As you press your foot on the brake, it creates hydraulic pressure within the cylinder, and that in turn pressurises fluid that is flowing through a network of brake pipes and brake hoses. As this fluid cannot be compressed, it activates a piston within each wheel’s hub assembly which, in turn, forces friction material onto the rotating parts of the wheel, stopping the vehicle.

A drum brake system is made up of hydraulic wheel cylinders, brake shoes and a brake drum. When the foot brake pedal is applied, two curved brake shoes, which are lined with friction material, are forced by hydraulic cylinders against the inner surface of the rotating brake drum. The result of this pressure produces friction which allows the vehicle to slow down or stop.
