LuK LMC451 clutch master cylinder for the 1995 BMW M3 6-cylinder 3.0L, the 1996-1998 M3 6-cylinder 3.2L and other vehicles turns pedal force into hydraulic pressure that works the clutch. It is the pedal-side part of the hydraulic release system, which meters how the clutch engages and releases.
- Integrated travel sensor where required, which senses clutch pedal position for start-stop, hill-start and speed control
- Peak torque limiter where required reduces hydraulic volume flow during sport driving to help prevent powertrain overload on sudden starts
Quick facts
- Part: LuK LMC451 clutch master cylinder
- Fits: the 1995 BMW M3 6-cylinder 3.0L, the 1996-1998 M3 6-cylinder 3.2L and other vehicles
- Condition: New
A soft or sinking clutch pedal, hard shifting or fluid near the pedal can mean the master cylinder is wearing out. A leaking slave cylinder can produce a similar pedal feel, so these signs alone do not prove this part is the problem.

Frequently Asked Questions
Will the LuK LMC451 fit a 1996-1998 BMW M3 6-cylinder 3.2L?
Yes, LuK LMC451 fits the 1996-1998 BMW M3 6-cylinder 3.2L and the 1995 M3 6-cylinder 3.0L, one per car; open the "Vehicles it fits" section for other models and engines.
Does the LMC451 clutch master cylinder include the push rod?
Yes, the push rod and installation instructions are included. The slave cylinder and heat shield are not, and this master cylinder is not pre-filled or pre-bled.
What does the travel sensor on a LuK clutch master cylinder do?
Where one is needed, LuK builds in a travel sensor that reads the clutch pedal position. Start-stop systems and functions such as hill-start and speed control use that signal.
Does the LuK LMC451 replace number 21 52 6 758 829?
Yes, the LuK LMC451 is cross-referenced to 21 52 6 758 829; the Interchange line on this page lists the other numbers it replaces.
What is the peak torque limiter in a LuK clutch master cylinder?
Where required, it reduces volume flow in the hydraulic system during sport driving. That helps keep a sudden start, like slipping off the clutch pedal, from overloading the powertrain.
