In addition to the materials used, the design of high temperature shaft seals is also crucial for their performance. The seal must effectively block the passage of fluids or gases through the interface between the moving shaft and stationary housing. This requires precise engineering to ensure a tight fit and proper sealing under varying temperature and pressure conditions.

A drum brake self-adjuster repair kit typically includes all the necessary components to restore the functionality of the self-adjuster mechanism. The kit generally consists of an adjusting screw, spring, lever, and sometimes additional hardware such as clips and cotter pins. These parts work together to maintain the correct position of the brake shoes, ensuring even pressure across the drum and preventing excessive wear.
