Product Details and Specifications

The Luk LMC503 clutch master cylinder is a new replacement component engineered to restore proper clutch function in Chevrolet LUV vehicles. It comes with a push rod included, facilitating a complete installation without the need for additional parts. While the unit does not include a heat shield or clutch slave cylinder, it is compatible with existing clutch slave cylinders in the vehicle.

Since the unit is not pre-filled or pre-bled, it is important to manually bleed the clutch hydraulic system after installation to remove air and achieve correct pedal feel. Verify all connections for leaks and proper alignment during installation.
