Brake drum principle
The braking principle of brake hub is to pull or push the hub in the brake hub, so that the shoes on both sides are close to the inner wall of the wheel, and then achieve the effect of braking.
The wheel is rolling forward, and the forward rolling force will act on the brake hub in the opposite direction. With the overall contact between the brake hub and the wheel, the braking force will increase instantaneously, so it has obvious braking effect. Disc brake is also known as disc brake, disc brake through the hydraulic pump to promote brake calipers, and hold the brake disc. And brake brake force and drum brake are different. It's more linear, so it doesn't suddenly increase. To increase braking force, methods of increasing braking area are commonly used.
If the use of double piston calipers, can also be extended by means of brake arm, can be amplified by means of hydraulic pump pressure and then increase the pressure.
Whether it's the brake hub or something else, any machine will wear out over time
