When we push the brake lever to slow down our car the system of brakes absorbs energy that is generated during its movement. The motion is accomplished through friction between two components that are fixed like the brake shoes and a moving component like the drum.
This stops the motion of the wheels of the car and converts the energy that is generated into heat. When it comes to drum brakes, they’re still being used in vehicles with lower end models. Why? We’ll explain them in this article.
A drum brake for cars is a kind of brake which, once the car’s pedal is released, generates friction in the brake shoes, which then press against the inner surface of the drum that is connected to the axle wheel of the vehicle.
The importance of drum brakes
The brake system in vehicles is more than the handbrake and pedal that operates when we use it or need to stop the vehicle. It is much more. It’s a complete system that helps us stay safe when driving.
In this particular instance the drum brake usually situated on the rear wheels is comprised of several components that, when put together and operated are very easy: brake drum, brake shoes, brake plate and hydraulic cylinders among other components in the drum brake.

Why is this drum brake mechanism in our vehicle so important?
If we are using the brake system properly and properly, the drum brake is going to begin immediately when you push the pedal to brake. The drum shoes are pressed into the drum that brakes, and can stop motion of the car due to friction.
Benefits and drawbacks of drum brakes
As motorists, we should be aware of the fact that any issue on the drum brakes in our vehicle, can cause it an issue when driving. Sometimes it may mean we may be involved in an accident.
Benefits of the drum brake
Cost reduction. The primary benefit that drum brakes have is their lower cost, as well as being an extremely efficient and long-lasting system. Thus, unlike disc brakes, the cost of the drum brake’s components is significantly cheaper than parts available used for disc brakes. This is a major distinction between disc brakes as well as drum brake.
Simple installation. If we wish to replace the components that make up the drum brake we should ensure that the process of installing the brake mechanism isn’t difficult. It can take one and two hours.
Protection from atmospheric agents. If your vehicle still has drum brakes, one advantage is that they guard the brake system from ice, water and mud. They make the perfect component in difficult conditions and on secondary roads.
The disadvantages of drum brakes
The components need an initial break-in time. Contrary to disc brake pads, brake shoes need longer breaks in. When replacing these parts it is advised to stay clear of sudden braking for the initial 300 km. Furthermore, it’s also not recommended to perform an MOT brake test because braking isn’t nearly as efficient.
Poor heat dissipation. This is due to the fact that drum brakes don’t have the ability to disperse the heat produced through friction. The brake system is prone to heat up rapidly. The brake drum begins to deform and, as a result being drivers, we must push the brake pedal more in order to bring the vehicle to an end.
