Explore our high-performance brake master cylinders, wheel cylinders, and load-sensing valves manufactured to meet stringent global quality frameworks.
In the modern automotive landscape, safety and performance are inseparable from precision engineering. As a leading high-quality car performance factory group, Wuhu Qiujing Auto Parts Co., Ltd. has established itself as an industry benchmark since our founding in 2007, building on a technical heritage that traces back to 1996. Over the past two decades, we have continuously advanced our research and development in hydraulic braking systems, ensuring our master cylinders, wheel cylinders, and proportioning valves exceed OEM specifications.
Our 6,000 m² manufacturing plant operates under the strict regulations of IATF 16949:2016 and ISO 9001:2015. By utilizing advanced CNC machining centers, automated hone-lapping technology, and computerized pneumatic/hydraulic leak testing, we produce over 2 million units annually. These metrics represent our commitment to safety, engineering integrity, and long-term durability for clients worldwide.
Explore our six main hydraulic product lines. Each line is designed, manufactured, and verified under aerospace-grade precision to guarantee zero-defect safety performance.
A comprehensive analysis of metallurgy, seal design, and brake system integration for future vehicle architectures.
Brake master and wheel cylinders are subjected to severe cyclical stress, operating at hydraulic pressures often exceeding 100 bar (1,450 psi). To prevent internal pressure bypass, the inner bore must maintain precise tolerances and low surface roughness. Our factories utilize diamond honing heads to achieve surface finishes below Ra 0.2 microns. This process minimizes seal wear and ensures consistent volumetric efficiency over millions of stroke cycles.
EPDM (Ethylene Propylene Diene Monomer) elastomer seals are a critical wear component in hydraulic systems. We source premium-grade EPDM formulated to withstand extreme temperature ranges (-40°C to +120°C) and resist chemical degradation from modern glycol-ether-based fluids (DOT 3, DOT 4, and DOT 5.1). Our advanced compounding processes prevent seal swelling and softening, eliminating a common cause of fluid leakage and pressure loss in high-demand fleet environments.
The automotive industry is transitioning toward hybrid and fully electric drivetrains. In these architectures, regenerative braking changes the pressure distribution requirements within the hydraulic circuit. Traditional vacuum boosters are being replaced by electromechanical brake boosters and active brake actuators. Wuhu Qiujing is actively designing next-generation brake master cylinders configured to handle rapid, high-frequency pressure changes from automated emergency braking (AEB) systems.
Additionally, we are exploring weight reduction through aluminum alloys like AlSi1MgMn. Replacing traditional nodular cast iron with these alloys reduces unsprung mass, supporting vehicle range extension and lowering carbon emissions. This engineering direction ensures our products remain compatible with evolving vehicle platforms.
Established in 2007, Wuhu Qiujing Auto Parts Co., Ltd. is a specialized manufacturer and supplier of safety-critical braking system components. Our product line includes brake master cylinders, brake wheel cylinders, clutch master cylinders, clutch slave cylinders, and brake proportioning valves. Under the leadership of our founder, who has been active in automotive hydraulics since 1996, the factory has developed thousands of models designed for light commercial vehicles, passenger cars, and heavy-duty trucks.
Our facility is located in Wuhu, Anhui Province—a prominent automotive manufacturing hub in China. This location allows us to leverage localized raw material access, skilled engineering personnel, and efficient logistics infrastructure to deliver cost-effective and reliable products to clients globally.
The automotive supply chain requires high reliability and cost efficiency. Our Wuhu facility manages production risk through vertical integration of manufacturing stages, including casting, precision machining, seal assembly, and pressure testing.
By sourcing raw materials from local specialized foundries, we minimize transportation delays and ensure consistent alloy quality. We also utilize multi-station CNC machines to reduce cycle times and maintain tight tolerances. This domestic supply chain setup protects our international partners from supply disruptions, allowing us to maintain stable lead times even during market volatility.
Vehicles operate in diverse global environments, requiring components that perform reliably in extreme conditions. Wuhu Qiujing optimizes its hydraulic cylinder formulations based on regional field data:

We follow IATF 16949:2016 guidelines at every step of production. Our quality control team performs initial material analysis, monitors CNC dimensions, conducts automated surface roughness checks, and runs 100% pneumatic/hydraulic pressure leak tests on every cylinder before packing.
Yes. Our in-house engineering team can develop custom components based on OEM drawings, physical samples, or CAD files. We verify fitment and functional performance using solid modeling tools and test prototypes.
We use HT250 gray cast iron or QT450 nodular cast iron for standard applications to balance durability and cost. For weight reduction, we offer anodized 6061-T6 aluminum alloys. Pistons are typically made from chrome-plated steel, aluminum, or phenolic resin, depending on OEM specifications.
For catalog items that utilize existing tooling, the MOQ typically ranges between 50 to 100 units per part number. Standard production lead times are 30 to 45 days, depending on order size and scheduling. Custom development projects require additional time for tooling design and validation.
Our standard EPDM seals are designed for glycol-ether fluids (DOT 3, DOT 4, and DOT 5.1). If your application requires silicone-based DOT 5 fluid, please specify this during the inquiry stage. We will configure your order with compatible fluorocarbon or customized silicone seals to prevent leakage.
