Detailed Product Description
The Centric C-TEK Standard Brake Master Cylinder 131.40049 features a durable aluminum construction for the master cylinder body, paired with a plastic reservoir designed for longevity and resistance to brake fluid corrosion.

With a bore diameter of 0.875 inches (22.225 mm), this master cylinder provides precise hydraulic pressure control essential for safe braking performance.
