What is the Difference Between Drum Brakes and Disc Brakes?
1 Answers
The main differences between drum brakes and disc brakes are as follows: 1. Different braking methods. Drum brakes use hydraulic pressure to push the brake shoes against the inner edge of the brake drum during braking, generating friction to inhibit the rotation of the tires and achieve braking. Disc brakes have flat brake pads on both sides of the brake disc. When hydraulic pressure from the master cylinder is delivered to the wheel cylinder, the brake pads clamp onto the brake disc to achieve braking. 2. Different components. Drum brakes consist of a brake backing plate, wheel cylinder, brake shoes, related linkages, springs, pins, and the brake drum. Disc brakes are hydraulically controlled, with main components including the brake disc, wheel cylinder, brake caliper, and hydraulic lines.
