Direct manufacturer-to-distributor quotes featuring high-precision hydraulic parts engineered to OEM standards.
Deep analysis of the technical evolution, safety benchmarks, and supply constraints governing the production of critical braking elements like the 46010-72Y04 series.
Modern production utilizes high-density anodized aluminum housing that significantly minimizes friction coeffecients while maximizing burst pressure tolerances, ensuring long-term safety in variable climates.
Utilizing high-grade EPDM rubber seals for resistance to corrosive DOT 3, DOT 4, and DOT 5.1 brake fluids. Eliminates micro-leakage risks and pedal sponginess under extreme operating temperatures.
Micro-honed piston bores with precision tolerances down to the micron level reduce piston wear, optimize fluid return velocity, and enhance overall master cylinder assembly lifecycle.
The 46010-72Y04 Brake Master Cylinder (along with its interchangeable counterparts 46010-72Y14, 46010-72Y24, 46010-72Y74, and 46010-Y02G1) is a critical hydraulic unit designed for optimal performance on Nissan vehicle platforms. As a primary pressure generator in the brake system, this component translates mechanical force from the brake pedal into hydraulic pressure directed to the calipers and wheel cylinders.
At our state-of-the-art facility, our manufacturing processes prioritize physical dimensions accuracy and material integrity. Heavy-duty castings, pressure chambers designed to withstand intense stress cycles, and exact matching of ports guarantee that replacement parts offer a seamless drop-in fit. Our engineering practices respect the original equipment manufacturer (OEM) specs to prevent typical aftermarket problems like premature piston seal failure and hydraulic pressure lag.

Wuhu Qiujing manufactures a comprehensive range of automotive safety components designed for diverse international vehicle applications.
High-integrity primary pressure cylinders for major automotive platforms.
Dependable rear drum brake cylinders ensuring balanced braking torque.
Smooth mechanical translation for manual transmission vehicles.
Durable engagement actuators engineered to withstand millions of cycles.
Optimal pressure distribution preventing rear wheel lockups during heavy braking.
Precision-cast calipers engineered for rapid heat dissipation.
Different regions present unique challenges for brake components. We adapt our manufacturing processes to meet these environmental demands.
In hot and humid markets (such as Southeast Asia and parts of Latin America), condensation can accelerate external corrosion. Our 46010-72Y04 units undergo an advanced anti-oxidation surface treatment to prevent rust and maintain cylinder integrity over time.
For operations in desert regions like the Middle East, dust particles can damage cylinder seals and contaminate hydraulic fluid. We use high-precision EPDM dust boots that create an effective barrier, protecting the inner piston assembly from abrasive dust ingress.
In cold regions like Northern Europe and North America, low temperatures can cause standard rubber seals to contract and leak. Our custom-formulated EPDM seals remain flexible and maintain their sealing performance down to -40°C, ensuring reliable operation in winter climates.
