Types of motorcycle brakes and how they work

By now, we all know that brakes are the most important safety system on our motorcycle. However, it never hurts to be reminded. For this reason, it is essential that we understand how all types of brakes and braking systems work, as this knowledge can be vital for our safety and for that of everyone else sharing the road with us.

Today we’re going to talk about disc brakes and other types of braking systems, explaining how each one works.

Disc brake

The disc is the surface against which the brake pads act to slow the motorcycle down. When the brake is applied, a hydraulic pump is activated and sends brake fluid toward the calipers. The fluid pressure causes the pistons to push the pads, creating friction against the brake disc and progressively decelerating the bike. This deceleration generates heat, which is dispersed through the disc.

Disc brakes are currently the most common braking system on medium- and high-displacement motorcycles used on the road. Some have their own particular features. For example, MotoGP races use carbon brake discs, while Moto2 and Moto3 use steel brake discs with an aluminium core, like those from NG Brakes.

Drum brake

Generally, these types of brakes are only used on low-displacement motorcycles. When the brake is applied, the brake shoe expands and comes into contact with the brake drum, while the springs keep the shoes in position. Finally, the adjusting lever helps tighten the shoes to brake as efficiently as possible.

CBS brakes

The CBS system stands for Combined Braking System. This braking system ensures that when the rear brake is applied, the front brake is automatically activated as well, providing a more balanced stop and reducing braking distance by up to 50%.
