The motorcycle brake lever is a component of the braking system that holds the brake pads and applies braking force to the rotor or drum. The pin is a metal piece that is used to secure the brake lever to the fork bracket or wheel bracket. The spring is a component that helps return the brake lever to its original position after it has been activated. This helps maintain proper tension on the brake lever, ensuring that the brake is activated smoothly and precisely.Referencia: HR9030
