The working principle of the brake shoe: the core component of the automobile brake system
The brake shoe is an important part of the automobile brake system, which is mainly responsible for slowing down or stopping the vehicle through friction. When the driver steps on the brake pedal, the brake fluid pressure increases, pushing the piston to squeeze the brake shoe, so that the brake shoe is close to the brake drum to generate friction, thereby achieving the effect of deceleration or parking. Therefore, the state of the brake shoes directly affects the safety performance of the vehicle.
