The present invention relates to a spring component of an automotive braking system and a fabrication technique thereof. The spring component of the automotive braking system is composed of a spring (3), a spring holder (4), an anti-thrust sleeve (1), a riveting pin (5) and gaskets (2). Each part is standardized to the max in order to create conditions for mass production and further reduce cost.In the process of production, clean production environment is required, so that the pollution on brake fluid can be kept at the minimum level when the spring component is used, and therefore the braking performance is increased. The fabrication technique of the spring component ensures that the load attenuation rate cannot be larger than 3 percent after 10 million operating cycles, thus ensuring the safety performance. The spring component is characterized by high braking performance, high standardization degree, long service life and low cost.
