Replacement Brake Master Cylinder Compatible with Nissan A12 / A14 Engines – 17.46mm

Maintain safe and dependable braking performance in your classic Nissan with this Replacement Brake Master Cylinder, specifically designed for vehicles powered by A12 and A14 engines. Featuring a precisely machined 17.46mm bore, this unit restores balanced hydraulic control and consistent brake pedal feel, addressing issues like fluid leaks, soft pedals, or reduced braking efficiency. Built to meet original specifications, it offers a direct-fit solution that seamlessly integrates with the vehicle’s braking system without requiring modifications. With high-quality materials and a corrosion-resistant design, this cylinder is ideal for vintage restorations, daily drivers, or preventative maintenance on long-serving Nissan models. \n \nDesigned for compatibility with Nissan A12 and A14 engine-equipped models: This master cylinder is purpose-built to suit early Nissan vehicles that use the A12 and A14 engine platforms. It provides exact mounting and fluid port positioning for a seamless fit, making it ideal for Datsun and early Nissan sedans, coupes, or utility models from the same era. \n \n17.46mm bore delivers precise hydraulic pressure and brake balance: The smaller bore diameter is ideal for matching the stock brake system requirements, promoting smooth pedal action and well-balanced braking between front and rear circuits. This sizing restores the vehicle’s original braking characteristics, ensuring safe, responsive stopping across a range of driving conditions. \n \nRobust construction with corrosion-resistant finish: Made from high-strength cast metal and treated with a protective anti-corrosion coating, this cylinder is built to resist wear from moisture, brake fluid exposure, and temperature changes. It maintains structural integrity over time, making it especially suited to classic vehicle restorations and long-term use. \n \nHigh-performance internal seals prevent leaks and fluid degradation: Equipped with premium-grade rubber seals and a finely finished piston, this master cylinder prevents hydraulic fluid leaks and protects against internal air ingress. It helps maintain system pressure and improves long-term braking reliability, reducing the risk of pedal fade and inconsistent braking force. \n \nRestores factory pedal feel and overall system responsiveness: A worn or leaking master cylinder can lead to a soft pedal, delayed braking, or the need for excessive pedal travel. This replacement unit restores a firm, responsive feel underfoot, allowing for predictable brake modulation and improved vehicle control under normal or emergency braking conditions. \n \nOEM-style fitment for simple installation: Designed with original factory specifications in mind, the cylinder bolts into place using existing hardware and mates cleanly with stock fluid lines and boosters. This direct-fit compatibility means no cutting, fabrication, or retrofitting is required, making the installation straightforward for mechanics or skilled DIYers. \n \nPreserves braking system health and component longevity: Consistent pressure delivery helps extend the lifespan of calipers, wheel cylinders, pads, and shoes. By restoring proper fluid flow and sealing integrity, this master cylinder reduces wear on downstream components and supports safer, more efficient braking over time. \n \nThis Replacement Brake Master Cylinder Compatible with Nissan A12 / A14 Engines – 17.46mm is a high-quality solution for restoring the original braking feel and function in your classic Nissan. Its compact bore, rugged construction, and leak-proof design ensure reliable performance, while its direct-fit layout simplifies the repair process. Whether you're preserving a vintage Datsun or keeping a long-serving workhorse on the road, this component helps maintain safety and drivability without compromise. \n \nPlease refer to the image to ensure suitability.
