Difference Between Disc Brakes and Drum Brakes in Bikes

On the safety front, the most important thing is the braking system in any bike. People are often confused with disc brakes and drum brakes and can not decide which is better. In fact, companies also offer two-wheeler’s models in these two types of braking flavours. So what after all is the difference between disc brakes and drum brakes in bikes and scooters ? 

Diskbrake vs Drumbrake in bikes

At present, most new bikes have a disc brake. There are just a few bikes that have drum brakes. Most bikes have a disc brake in its front wheel. For your information, the break of front wheel is 70 percent more effective to control the speed, while the rear break is 30 percent.

Now the question arises that drum brakes are better or disc brakes. Then, as a matter of fact, both the breaks have some advantages and disadvantages.

Working Mechanism

A Drum Brake in Action

A drum brake uses friction created by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term drum brake usually means a brake in which shoes press on the inner surface of the drum.

A Disk Brake in Action


A disc brake is a type of brake that uses calipers to squeeze pairs of pads against a disc in order to create friction that retards the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary.

Drum brake has heat limitations

The major difference in disc brakes and drum brakes is seen in heat when the bike is gets hot.In this situation, when the drum brake is applied, then with its brake shoe, there is more heat production due to friction. In this case, drum brakes can not prove to be effective.

While, the disc brakes are not affected in such a situation. It stops the wheel promptly after breaking.

Unlike Disk Brakes , Drum Brakes is less effective is rainy season.

In the rain, when the wheel of the bike becomes completely wet, at that time when the drum brakes are applied, the correct hold between the brake shoe and the lining will not be able to get the brakes efficiently. While, rain does not have a special effect on the disc brakes and the bike stops as soon as the breaks occur.

Drum brake needs more maintenance

It is difficult to maintain a drum brake. The dust gets accumulated over the drum brake. Besides, there are several small parts in it that have to be adjusted.

While, it is easy to maintain the disc break, and the entire break system is self – adjusting.
