Thanks to modern technology, there has been a tremendous development in the field of car brakes. The use of sensors, computers, and many other engineered parts help make your ride smooth and safe. One doubt that most of the vehicle owners have regarding braking is the difference between disc brakes and drum brakes, and which one is better. Let’s check out the differences between the two –

  1. Working – In the case of drum brakes, the two arch shaped shoes present inside the drum expand in the outward direction into the inner wall of the spinning drum, with the help of hydraulic force and centrifugal force. This, in turn, generates friction and your car, thus, slows down.

The working of a disc brake is a bit more complicated. Upon pressing the brake pedal, brake fluid enters into the calliper. And a metal piston present inside the calliper gets pressed against the back of each brake pad. The pad’s friction is thus transmitted to the spinning rotor, thus, slowing down the brake rotor and your car.

  1. Heat dissipation – Drum brakes aren’t effective while cooling. The heat dissipation is a real trouble in case of drum brakes. But, enter the modern era of disc brakes, and you have a much better heat dissipation capacity. The disc brakes have vane like structure that helps in better dissipation of heat.
  1. Maintenance – The maintenance of drum brakes is much easier as compared to the disc brakes. The all-in-one design of drum brakes is what makes it so easy to handle and maintain. When you have some repairing issue regarding the brake of your vehicle, then drum brakes are much easier to be repaired in comparison with the disc brakes.
  1. Initial pressure – The initial brake pressure is more in the disc brakes as compared to the drum brakes.
  1. Construction – Drum brakes are the older versions of brakes that are extremely simple and have a low manufacturing cost. These are made from cast iron and have a drum-like shape. All the components of a drum brake are well confined within the drum. Although they are outdated, yet you can find many varieties of cars that use these drum brakes. Disc brakes, on the contrary, are the present generation of brakes having a large metal rotor, 2 flat brake pads, and a hydraulic calliper. They have a number of components, with different advanced functionalities, in comparison with the drum brakes.

On the whole, it is very safe to say that if you like putting efficiency and safety over the cost and all other minor considerations, then you better chose disc brakes over drum brakes.
