What is the Working Principle of Disc Brakes?

[VanAnthony]

Disc brakes work by forcing hydraulic fluid into the inner and outer wheel cylinders during braking. The pistons, under hydraulic pressure, press the brake pads against the brake disc, generating frictional torque to achieve braking. Applications of Disc Brakes: Disc brakes are widely used in passenger cars, with most vehicles employing them on all wheels. Some cars use disc brakes only on the front wheels, paired with drum brakes on the rear wheels, to enhance directional stability during braking. In commercial vehicles, disc brakes are gradually being adopted in new models and high-end variants. Features of Disc Brakes: Disc brakes are hydraulically controlled and consist of key components such as the brake disc, wheel cylinder, brake caliper, and hydraulic lines. They offer advantages like rapid heat dissipation, lightweight construction, simple design, and easy adjustment. Particularly under high loads, they exhibit excellent high-temperature resistance and stable braking performance.
