LuK has been at the forefront of hydraulic clutch actuation technology development for decades. Each component is 100% functionally tested to meet or exceed OEM performance specifications. Beyond basic clutch operation, modern clutch master cylinders support important vehicle functions including cruise control, starter interlock systems, electric parking brake, and start-stop systems. LuK recommends replacing hydraulic components during clutch service since plastic components cannot be rebuilt and worn hydraulics can cause clutch release problems.
