Function of brake hose sleeve spring

The function of the brake hose sleeve spring is to quickly restore the two friction plates to the original state without braking. The inner cavity of the brake hose is provided with a reinforcing rib, and the surface of the reinforcing rib is wrapped with a tension spring, which not only effectively strengthens the strength of the brake hose, but also prevents the brake hose from being deformed or damaged when it is impacted by external force, and protects the spring.
