Detailed Product Information
The clutch master cylinder converts pedal movement into hydraulic pressure for the clutch release system. When this component wears or leaks, pedal feel can change and clutch operation can become inconsistent. The LuK LMC725 is an OE-quality replacement from Schaeffler’s LuK brand, which has a long history in hydraulic clutch actuation technology and manual transmission components. This part cross-references Monroe Shocks & Struts (e.g., 37230-FJ021, 5110819100) for the same application.
For Subaru Forester, Subaru Crosstrek, Subaru Impreza, and Subaru XV Crosstrek applications, this part supports direct replacement service on vehicles equipped with the matching hydraulic clutch system. The LMC725 is intended for repair work where the original master cylinder has failed, leaked, or no longer delivers consistent hydraulic pressure.
What This Part Helps Address
- Soft, inconsistent, or changing clutch pedal feel
- Hydraulic fluid leakage at the master cylinder
- Difficulty disengaging the clutch cleanly
- Reduced clutch release consistency during shifting
Installation Notes
Review the included installation instructions before beginning service. Because this unit is not pre-filled and not pre-bled, the hydraulic system must be filled and bled after installation. Confirm that the clutch slave cylinder condition is acceptable before replacing only the master cylinder.
Quality Assurance
LuK, under Schaeffler, supplies OE-quality clutch release system components for the independent aftermarket. The LMC725 is a new replacement part built to match the hydraulic clutch actuation requirements of the listed Subaru applications.
