Detailed Description

LuK has extensive experience in hydraulic clutch release systems, and that engineering background is reflected in the LMC100 clutch master cylinder. This unit is built for Acura Legend manual transmission service where a direct hydraulic master cylinder replacement is needed. The aluminum housing, female connector, and included push rod support a straightforward service replacement, while the 15.87 mm bore helps maintain the hydraulic volume required for clutch actuation. This part cross-references Dayco 72100 for the same application.

What It Helps Address

• Soft or inconsistent clutch pedal feel
• Loss of hydraulic pressure in the clutch system
• Difficulty disengaging the clutch
• Fluid leakage from a worn master cylinder
• Pedal travel issues caused by internal seal wear

Installation Notes and Tips

Verify the bore diameter, connector style, and vehicle application before installation. Because the reservoir is not included and the system is not pre-filled or pre-bled, the hydraulic circuit must be filled and bled after installation. Follow the included instructions and inspect the clutch hydraulic line, slave cylinder, and related seals for wear before returning the vehicle to service.

Quality Assurance

LuK is part of Schaeffler’s clutch release system expertise, with a long history in the transition from mechanical to hydraulic clutch actuation. The LMC100 is a new replacement part built for service use on Acura Legend applications.
