KingStar wheel cylinders are factory tested with a pressure of 45 psi of dry air to ensure unmatched robustness. The test checks for porosity, leaks, presence, position and quality of cups, surface finish of bores and bleeder seal. All castings meet S.A.E. J431 Standards, and bleeder screws are case hardened for long, reliable life. Brake cups meet S.A.E. Standard J1601. Durable boots are made from premium EPDM rubber, meeting S.A.E. Standar J1604. KingStar wheel cylinders have been the reference accross North America for over 40 years.
Exclusive G3000 heat-flowed castings iron and aluminum give our wheel cylinders the ideal balance between tensile and hardness
Meets the brake performance requirements of SAE J1153 and J1154 testing, providing reliability and quality
Pressure tested to ensure safe and confident braking
Trivalent coated bleeder screws provide extra protection and added durability
Made with high quality EPDM rubber cups and boots for long lasting performance
Wheel cylinder bores are surface tested to ensure an optimum sealing surface for the pressure cups
Due to repair time and cost, it is more desirable to replace instead of repair wheel cylinders
Recommended replacement is suggested when servicing drum brake
