Disc Brakes vs. Drum Brakes
Today bikes are getting faster and more powerful by the day. Travelling at scorching speeds is the new way to travel for many. The roads becoming smoother and wider has allowed for quicker travel. But we know that staying in a country like India, however wide the roads get and the smoother it is, one can never know what might jump out in front of you out of a sudden. Now no offence of stereotyping here, but still something like this is pretty standard across the World. Hence for all that power harnessed, generated and turned into scorching speeds; there is an equal importance for good stopping power as well. Many riders have confuse about Disc Brakes vs. Drum Brakes and have many question which is better. So today we will discuss about Disc Brakes vs. Drum Brakes.
Total idea about Disc brakes vs Drum brakes
To compare and contrast disc brakes and drum brakes, it is necessary to get an idea of the underlying principles involved. A brake is a retardation device which converts energy from one form to another. Here, the kinetic energy of the moving wheels is converted into heat energy by means of friction between the brake pad and contact surface. A brake’s efficiency is determined by its ability to convert kinetic energy to heat energy and also by the rate at which this heat is dissipated. Now, that key concept is understood, let’s look at the two brake systems.
Drum Brakes Explained
Drum brakes, as the name suggests are in the shape of a drum. This drum moves along with the vehicle’s wheels. The main components of the drum brake are brake pads and piston. When the brakes are applied, brake fluid forces the piston to push the brake shoes outwards against the spinning drum. The friction causes the vehicle to come to a stop.
Disc Brakes Explained
Disc brakes have a rotating disc which rotates along with the wheel. Brake pads are present on both sides of the disc, which when pressed against the brake, forces the vehicle to come to a stop. When the brake pedal is applied, brake fluid pressure forces the piston to press the brake pads against the disc. Conversion of energy takes place and the vehicle comes to a stop. The Disc is usually provided with vent holes which allow heat to dissipate quickly.
Disc Brakes vs. Drum Brakes
Look at the last point under disc brakes. Vents present on the disc improve the heat dissipation rate. Also, they are exposed to air whereas the drums are not. In a vehicle equipped with drum brakes, excessive friction causes a surge in temperature due to which the drum expands outward. Because of this, more effort has to be exerted to bring the vehicle to a stop. Like I said in the previous section, heat dissipation rate is directly proportional to efficiency of the brake. Another disadvantage of drum brakes is that they are pretty useless when exposed to water.
In a nutshell, Disc brakes are easier to inspect, have fewer parts, have a superior design and better stopping power. The only advantage Drum brakes have is that they are cheaper to manufacture.
