Reliable Clutch Master Cylinder for Chevrolet and GMC Vehicles

The Luk LMC128 clutch master cylinder is engineered to provide consistent hydraulic pressure for smooth clutch operation in select Chevrolet and GMC trucks and SUVs. Designed with durable iron construction, this new part ensures long-lasting performance for manual transmission systems.

Constructed from robust iron material for durability
Includes push rod for direct installation
Female connector gender for proper hydraulic line fitment
Installation instructions included for ease of replacement

New part, not pre-filled or pre-bled

Durable Design and Key Features

The Luk LMC128 clutch master cylinder is built to meet the demands of manual transmission systems in Chevrolet and GMC models such as the Blazer, C10, C1500, K5 Blazer, and others. Its iron construction provides strength and resistance to wear, while the included push rod and female connector ensure compatibility with existing hydraulic lines. This part is supplied new and requires bleeding during installation, as it does not come pre-filled with fluid or pre-bled. The absence of a reservoir and heat shield means it is designed to integrate with your vehicle's existing components.

Chevrolet Blazer, C10, C20, C30, C1500, C2500, C3500

Common Applications and Problem Resolution

The Luk LMC128 clutch master cylinder addresses several manual transmission issues, including:

Spongy or soft clutch pedal feel
Difficulty shifting gears smoothly
Hydraulic fluid leaks from the master cylinder
Clutch pedal sticking or failing to return properly
Loss of hydraulic pressure affecting clutch disengagement

Installation Notes and Tips

Installation of the Luk LMC128 clutch master cylinder requires basic mechanical knowledge and tools. The part includes a push rod and installation instructions to assist with replacement. Since the unit is not pre-filled or pre-bled, bleeding the clutch hydraulic system after installation is necessary to ensure proper function. Verify compatibility with your specific Chevrolet or GMC model before installation.
