Wuhu Qiujing Auto Parts Co., Ltd. — Pioneering Hydraulic Brake System Solutions Since 2007
Established in 2007, Wuhu Qiujing Auto Parts Co., Ltd. stands as a premier direct manufacturing exporter and developer of safety-critical hydraulic braking components. Our founder’s legacy in the automotive brake manufacturing sector dates back to 1996, instilling over 20 years of technical expertise into our team and standard operational processes.
Operating out of a modern 6,000 m² factory floor, we integrate full-cycle engineering, from computer-aided design (CAD) to tooling, precise CNC machining, multi-stage pressure testing, and final packaging. Our portfolio contains thousands of products, including Brake Master Cylinders, Brake Wheel Cylinders, Clutch Master Cylinders, Clutch Slave Cylinders, Proportioning Valves, and Calipers.
Underpinned by a dedication to "Safety First," our production and management processes adhere strictly to GB/T19001-2016 / ISO 9001:2015 and the automotive-standard IATF 16949:2016 quality certifications.

Shift from cast iron to lightweight aluminum alloys to reduce unsprung weight, matched with EPDM rubber seals for higher chemical stability under brake fluids.
As EVs utilize regenerative systems, the friction brake relies on hydraulic master cylinders that adapt dynamically to sudden electronic braking system changes.
Distributors and import agencies demand verified ISO 9001 and IATF 16949 certificates to comply with vehicle safety standards and reduce liabilities.
Modern automotive engineering is navigating a dual transition toward vehicle electrification and advanced driver-assistance systems (ADAS). While software controls vehicle velocities, the physical deceleration mechanism remains hydraulic. High-quality master and wheel cylinders are crucial fail-safe layers.
Friction materials and sealing technologies must withstand extreme operational temperature shifts. High-quality EPDM (Ethylene Propylene Diene Monomer) rubber cups, for instance, are standard in premium master and wheel cylinders. They resist wear and chemical breakdown from glycol-ether-based DOT 3, DOT 4, and silicone-based DOT 5 fluids. Cylinder bodies undergo hard anodizing or anti-oxidation electrophoretic coatings to prevent internal pitting, which can cause micro-leakages and pressure drops.
Automotive supply chains require high precision and structural resilience. Sourcing managers from North America, the EU, and South Asia look for tier-2 or tier-3 manufacturers with ISO/IATF certifications, predictable lead times, and low PPM (Parts Per Million) defect rates.
With rising logistics costs and demand fluctuations, buyers prefer suppliers who run flexible lines and can manufacture for varied regional car parcs. A factory that supports light commercial applications (like Isuzu ELF models) alongside volume passenger cars (like Toyota Wish or Nissan Versa) helps streamline importing and consolidation.
Combining raw material integration, automated precision manufacturing, and rigorous quality inspection to deliver global competitiveness.
Wuhu Qiujing Auto Parts leverages its strategic location within China's Yangtze River Delta automotive cluster. This gives us direct access to high-grade casting foundries, heat-treatment providers, and transport hubs, allowing us to keep production costs low while maintaining high quality.
By integrating computerized boring machines, precision honing setups, and automated testing benches, we keep dimensional tolerances under 0.01 mm. Every master and wheel cylinder is subject to 100% pneumatic pressure leak testing before assembly, ensuring zero out-of-box failures for our customers.
Our core product lineup covers critical fluid displacement and pressure distribution systems for passenger vehicles, utility trucks, and industrial equipment.

Analyzing localized stress points and system engineering for Japanese, American, and European light commercial vehicles.
Light trucks operating in urban logistics deal with frequent stop-and-go cycles under full payloads. These operating conditions put significant thermal stress on hydraulic systems, meaning clutch master cylinders (such as references 8-97162-963-0 and 8-97124-110-0) must withstand sustained high fluid temperatures without internal pressure bypass. Our cylinders use hard-wearing chrome pistons and internal return springs calibrated to preserve clutch feel over long service intervals.
In North America, vehicles log high annual mileage across varying climates. Master cylinders for GM (e.g., 15844166) and Chrysler systems require high resistance to cold-weather shrinkage in sub-zero winter temperatures, as well as high-temperature stability in summer. Custom-molded EPDM seals are tested to hold pressure down to -40°C, helping prevent cold-weather fluid loss.
For daily commuter cars, brake pedal feedback and response times are key to safety. Our manufacturing uses diamond-tipped honing tools to keep cylinder bore surfaces exceptionally smooth. This reduces wear on the seal cups, giving drivers a consistent pedal feel and predictable braking response.
Off-road and utility vehicles frequently deal with mud, sand, and moisture. Wheel cylinders (such as 47201-3D350) use dust boots designed to seal out external contaminants, protecting the bore from scoring and extending the life of the internal hydraulic assembly.
