Hold brakes and disc brakes are two different braking systems, and there are some noticeable differences between them.
Appearance and structure: The structure of the holding brake is relatively simple, while the disc brake is relatively complex. The brake is usually composed of brake pads and brake device, which is slowed down by pulling the iron strip through mechanical transmission to make the brake pad and brake device rub against each other. Disc brake includes brake disc, piston, oil pipe and other components, brake disc and vehicle rotation shaft connection, when stepping on the brake pedal, the brake oil in the oil pipe is compressed to promote the piston movement, so that the brake pads clamp the brake disc to achieve the braking effect.
Brake principle: The braking principle of the brake brake is to decelerate by friction between the brake pad and the brake device through mechanical transmission, while the disc brake is to decelerate through the friction between the brake pad and the brake disc.
Braking force: Generally speaking, disc brakes have stronger braking force than holding brakes, because disc brakes can control braking force by adjusting the distance between the piston and brake pads, while holding brakes are relatively difficult to control.
Cost and maintenance: The cost of holding brakes is usually lower than that of disc brakes, and later maintenance is relatively cheap. Due to the complex structure, the cost and maintenance cost of the disc brake are relatively high.
Application scenario: The brake is widely used in the bicycle industry, and some low-end electric vehicle markets will also use the brake. Disc brakes are widely used in the front wheels of automobiles, and some luxury sedans are equipped with disc brakes on all four wheels to improve safety.
In general, both hold brakes and disc brakes have their own advantages and disadvantages, and the specific choice of braking system depends on the application scenario and actual needs.
