TWZ(B) FOOT OPERATED AND DRUM BRAKE

Braking is undoubtedly the most important link in car safety, and the importance of brakes is self-evident. Good brakes can not only improve driving comfort, but also effectively protect the safety of people on board.

Today, Mr. Ma will tell you about one of the commonly used brake parts in the brake system: drum brake.

Drum brakes are generally also called brake drums, and their main structures include brake wheel cylinders, brake shoes, return springs and other parts.
Brake wheel cylinder: contains brake oil. When braking, the pressure of the brake oil pushes the internal piston to move outward, thereby pushing the brake shoes to open

Brake shoe: When braking, it contacts with the inner surface of the brake drum to generate frictional braking.
Return spring: When the brake is released, the brake shoe is pulled back to the initial position
