Hydraulic clutch release replacement

LuK has extensive experience in hydraulic clutch release systems, and the LMC158 reflects that background in a direct-fit replacement for select Mitsubishi Eclipse and Plymouth Laser models. This clutch master cylinder is built for vehicles that use a hydraulic clutch actuation setup, helping restore pedal-to-release-cylinder communication when the original unit is worn, leaking, or no longer maintaining pressure. This part cross-references Dorman - First Stop CM39766 for the same application.

Common issues this part can address

  • Soft or inconsistent clutch pedal feel
  • Hydraulic fluid leakage at the master cylinder
  • Difficulty disengaging the clutch
  • Delayed or incomplete clutch release
  • Loss of hydraulic pressure in the clutch system

Installation notes and tips

Fits 1997 Mitsubishi Eclipse, N/A. Fits 1990-1994 Mitsubishi Eclipse, N/A. Fits 1992-1994 Plymouth Laser, N/A. Fits 1992 Plymouth Laser, N/A, California and Canada. Fits 1990-1991 Plymouth Laser, N/A, Cruise Control. Verify hydraulic line routing, pedal connection, and vehicle-specific notes before installation. Because this unit is not pre-filled or pre-bled, the hydraulic system must be filled and bled after installation to remove air and restore proper pedal operation. The included push rod and instructions help support a straightforward replacement process.
