Engineered to meet the rigorous demands of Japanese domestic and global automotive standards.
Osaka has long been recognized as the industrial heartland of Japan, particularly famous for its Monozukuri (the art of making things) philosophy. The region hosts a dense concentration of precision metalworking, casting, and chemical engineering factories. This industrial cluster plays a pivotal role in supporting global automotive giants like Mitsubishi Motors, whose regional assembly plants and supply chains rely heavily on the high-grade components manufactured in the Kansai area.
For decades, suppliers in Osaka have set the benchmark for automotive hydraulic systems. The rigorous quality standards demanded by Japanese OEMs have forced local factories to innovate continuously. From advanced heat treatment processes to ultra-precise CNC machining of cylinder bores, Osaka's manufacturing ecosystem ensures that every brake master cylinder and wheel cylinder meets the highest safety and durability metrics.
Our production lines integrate these classic Japanese engineering principles with modern, automated manufacturing technology. By sourcing raw materials that match Japanese Industrial Standards (JIS) and employing strict quality gates, we deliver aftermarket and OEM-replacement parts that match the performance of original Osaka-manufactured components for Mitsubishi Lancer, Pajero, Outlander, and Fuso commercial vehicles.
Explore our comprehensive range of hydraulic braking and clutch control systems.
The heart of the hydraulic system, converting pedal pressure into hydraulic force with zero pressure loss.
Precision-engineered for drum brake systems, ensuring balanced force distribution to brake shoes.
Delivers smooth, responsive clutch engagement for manual transmissions under all driving conditions.
Works in tandem with the master cylinder to actuate the clutch release fork efficiently.
Regulates fluid pressure to prevent rear-wheel lockup during heavy braking maneuvers.
High-durability calipers designed for optimal heat dissipation and consistent stopping power.
In the automotive safety sector, there is no room for error. A vehicle's braking system is its most critical safety feature. As a leading manufacturer, we adhere to strict quality protocols that align with the highest global standards, including IATF 16949:2016 and ISO 9001:2015.
The internal bore of a brake master cylinder must be machined to extremely tight tolerances. Our factory utilizes advanced CNC honing machines to achieve a surface roughness of less than 0.8 Ra. This mirror-like finish reduces friction between the piston cup seals and the cylinder wall, preventing premature wear of the EPDM rubber seals and eliminating internal fluid bypass.
The rubber seals used in our cylinders are formulated from high-grade Ethylene Propylene Diene Monomer (EPDM). This material offers exceptional resistance to glycol-based brake fluids (DOT 3, DOT 4, and DOT 5.1). It maintains its elasticity and sealing properties across a wide temperature range, from -40°C to +120°C, preventing fluid leakage and pressure drops in extreme climates.
Every single cylinder that leaves our assembly line undergoes a dual-stage pneumatic testing process. The low-pressure test detects minor sealing imperfections, while the high-pressure test simulates emergency braking conditions up to 15 MPa. This 100% testing protocol ensures that zero defective units reach our global distributors.
We are a professional brake system parts manufacturer and supplier, mainly including brake master cylinder, brake wheel cylinder, clutch master cylinder, clutch slave cylinder, etc. Our founder has been deeply engaged in automotive brake parts since 1996. Through decades of industry experience and production technology, the factory has now developed dozens of models and thousands of products to ensure that they are suitable for different models and meet different road requirements.
Our products have obtained GB/T19001-2016/ISO 9001:2015 and IATF16949:2016 quality system certifications. "Safety first" is the core concept of our factory, and we actively promote the corporate spirit of "integrity, innovation, and efficiency."
The automotive industry is undergoing its most significant shift in a century, driven by electrification, autonomous driving, and environmental sustainability. These trends are directly impacting the design and manufacturing of hydraulic braking components.
To maximize the range of Electric Vehicles (EVs) and improve fuel efficiency in Internal Combustion Engine (ICE) vehicles, manufacturers are focusing heavily on weight reduction. Traditional cast-iron brake cylinders are increasingly being replaced by anodized aluminum alloys. Aluminum cylinders offer up to a 50% weight saving while maintaining excellent structural integrity and corrosion resistance. Our R&D team is actively expanding our aluminum cylinder product line to meet this growing OEM demand.
Modern hybrid and electric vehicles utilize regenerative braking to capture kinetic energy. This changes the duty cycle of the hydraulic braking system, which now acts as a secondary system during rapid deceleration. The brake master cylinder must work seamlessly with electronic brake boosters (such as Bosch iBooster) to provide a consistent pedal feel and rapid pressure build-up when mechanical braking is required. Our engineering department in Osaka and global R&D centers are optimizing cylinder design to ensure compatibility with these advanced electronic control units.
Looking toward the future of autonomous driving, we are exploring the integration of pressure and stroke sensors directly into the brake master cylinder body. These smart cylinders will provide real-time feedback to the vehicle's central computer, monitoring fluid levels, seal wear, and system pressure to enable predictive maintenance and enhance overall vehicle safety.

We utilize original OEM samples and detailed technical drawings to reverse-engineer and manufacture our cylinders. Every dimension, including mounting hole alignment, port threads, and piston stroke, is verified using coordinate measuring machines (CMM) to ensure a 100% perfect fit and function matching the original Japanese specifications.
Our cast-iron cylinders are treated with an anti-corrosion black paint or zinc plating, while our aluminum cylinders undergo an anodizing process. This creates a protective oxide layer that resists salt spray, moisture, and road chemicals, ensuring long-term durability even in harsh winter conditions.
We stand behind our quality by offering a 2-year warranty on all brake and clutch hydraulic components. If any product fails due to manufacturing defects within this period, we provide free replacements in your next shipment.
Yes, we offer comprehensive OEM/ODM services. We can customize the packaging boxes, print your brand logo on the cylinders (via laser marking), and design custom labels according to your market requirements, subject to minimum order quantities (MOQ).
With an annual production capacity of over 2 million units and a highly optimized supply chain, our standard lead time for a full container load is 30 to 45 days. For regular, high-demand items, we maintain safety stocks to facilitate faster dispatch.
