Disc brakes and drum brakes Who's brakes are more powerful




A lot of car enthusiasts are not unfamiliar with car braking systems divided into drum brakes and disc brakes, but what is the difference between them and where their respective advantages lie, today through this brake technology post, so that you have a more in-depth understanding of this.

Drum Brakes

The principle of drum braking is that in the brake drum, hydraulic pressure is applied to the piston of the brake wheel cylinder, and the piston pushes out the curved braking shoe. The friction material glued or riveted to the brake shoe presses against the inside of the drum, slowing down the rotation of the drum and the axle, and finally braking.

Disc Brake

Known as disc brakes, disc brakes were once used in aircraft and industrial applications. By applying hydraulic pressure to the caliper, the friction material (brake lining) grips the rotating brake disc. Unlike closed drums, the discs are open. One of the advantages of disc brakes is that the powder generated by friction between the friction pads and the discs is quickly thrown off and the heat is more quickly dissipated by the discs, resulting in better braking performance. Drum brakes are obviously relatively weak in this regard.
