Products Description
Brake Shoe Spring
A brake shoe spring is a key small component in a vehicle's drum brake system. Its main functions are: After braking, it pulls the pressed and expanded brake shoes back to their original position, separating them from the brake drum to avoid continuous friction that could cause excessive wear or brake drag. It ensures the stable position of the brake shoes in the non-working state, guaranteeing the normal reset of the brake system and maintaining braking efficiency and driving safety. It is usually made of high-strength spring steel, requiring good elasticity and durability to withstand repeated braking actions and vibrations during vehicle operation.
Our factory generally uses 72B steel to manufacture springs and conducts rebound tests over one million times to ensure the service life of the springs and that the products meet international standards. Here is the specific data information of this spring produced by our factory：

The Spring Manufacturing Process
Material Selection and Preparation
We carefully select 72B high-carbon spring steel wire rods and subject them to rigorous surface treatment, ensuring the material meets the highest standards for strength and durability.
Forming Processing
Our skilled technicians use CNC spring machines to craft high-quality springs with precision, ensuring every component meets strict geometric and mechanical specifications.
Heat Treatment
Through high-temperature tempering, enhance the spring's resilience. Optimizing its ability to absorb and release force efficiently while maintaining structural integrity.
Post-Processing
Our post-processing includes surface strengthening
treatments and meticulous finishing, enhancing both
the aesthetic appeal and service life of the springs,
ensuring they excel in performance and longevity.
