Centric Premium Brake Master Cylinders Product Line
The Centric Premium Brake Master Cylinders line focuses on delivering high-quality brake hydraulics components that meet or exceed OEM specifications. This product line emphasizes durable materials such as aluminum for the master cylinder and plastic for the reservoir, ensuring resistance to corrosion and wear. The 130.66031 part benefits from this engineering approach, providing dependable braking performance for heavy-duty trucks and vans.
Detailed Product Description
This Centric Premium Brake Master Cylinder 130.66031 features a robust aluminum body paired with a plastic reservoir designed for longevity and resistance to brake fluid corrosion. The single removable reservoir style simplifies fluid inspection and replacement. With a bore diameter of 1.250 inches (31.750 mm) and a straight bore type, it offers consistent hydraulic pressure for effective braking. The master cylinder includes a cap but does not come with mounting hardware, push rod, brake booster, or bleeder hoses, so these components must be sourced separately if needed.
