Wuhu Qiujing Auto Parts Co., Ltd.
Established in 2007, Wuhu Qiujing Auto Parts Co., Ltd. has developed into a premier manufacturing base for hydraulic brake control systems. Our founder's journey in the automotive brake sector dates back to 1996, instilling a legacy of manufacturing wisdom, technical precision, and unwavering reliability.
Operating from a state-of-the-art 6,000 m² factory, we run advanced casting, CNC machining, and quality inspection units. Our annual output capacity exceeds 2 million pieces, supplying Tier-1 distributors, commercial vehicle operators, and automotive aftermarket organizations worldwide.
Safety and performance are our guiding values. All product pipelines comply strictly with the rigorous requirements of GB/T19001-2016 / ISO 9001:2015 and the automotive-standard IATF 16949:2016 quality management frameworks.
Engineered to match precise OEM standards, our product lines deliver performance and system longevity under severe driving conditions.
The central pressure actuator of the hydraulic brake system. Machined from high-strength cast iron or lightweight aluminum alloy to withstand extreme burst pressures. Ensures consistent displacement of brake fluid across all calipers and wheel cylinders.
Essential actuators for drum brake systems. Feature precision bore finishing and highly durable EPDM rubber cups. These units prevent internal leakages, maintaining uniform friction against the brake drum for dependable stop times.
Converts pedal force into hydraulic control line pressure. Built with premium corrosion-resistant materials and low-friction pistons. Provides smooth gear changes and reliable clutch release mechanics over extended operational lifespans.
Actuates the release fork of the transmission unit. Internally treated to prevent wear, these units offer reliable piston movement and seal integrity, maintaining pressure control and reducing regular maintenance costs.
Controls the distribution of line pressure between the front and rear wheels. Prevents rear-wheel lock-up during high-deceleration braking, ensuring directional stability and passenger safety across all load variations.
Directs hydraulic clamping force onto the brake pads. Constructed for efficient heat dissipation to prevent brake fade. Tested under extreme loads to verify seal and caliper body durability.
Why Tier-1 buyers, industrial importers, and international automotive brands partner with Wuhu Qiujing.
By managing the entire production process from raw material inspection and precision casting to final test verification, we eliminate intermediary costs. This allows us to offer competitive factory pricing for high-volume orders. Standard pricing sheets are updated regularly to match global metals index movements.
We utilize automated CNC machine tooling alongside premium gray iron, ductile iron, and anodized aluminum. Bore machining achieves sub-micron tolerances, minimizing friction coefficients. This reduces early cup wear, ensuring our master and wheel cylinders maintain pressure over years of service.
With dozens of casting molds and over a thousand finished component designs, we serve commercial truck fleets, passenger vehicle programs, and aftermarket lines. Our engineering department can develop replacement components using customer drawings or physical samples, providing quick prototyping times.
Every product batch undergoes continuous stress testing. Our quality control protocol includes high-pressure leak testing, piston stroke evaluations, and chemical exposure tests. We confidently back our products with a comprehensive two-year after-sales quality guarantee.
Developing innovative solutions to meet the demands of modern logistics, electric vehicles, and automated driving systems.
To support automotive fuel efficiency and extend electric vehicle driving ranges, we are increasing the share of lightweight aluminum alloy configurations across our cylinder lines. This helps reduce vehicle weight without sacrificing structural strength or pressure limits.
Electric and hybrid vehicles place unique demands on hydraulic backup systems. We are designing low-drag caliper pistons and specialized master cylinder valves to integrate smoothly with modern regenerative braking controllers and anti-lock electronics.
We are adopting advanced zinc-nickel plating and eco-friendly surface coatings that meet global environmental standards (such as REACH and RoHS). These treatments provide excellent resistance to road salt spray and moisture, extending the service life of our components in harsh winter climates.
By installing robotic assembly lines and automated end-of-line diagnostic equipment, we capture and analyze pressure curves for every cylinder. This data-driven quality control helps ensure that only zero-defect parts reach the packaging stage.
Our manufacturing and quality control systems are fully certified under key international automotive standards.

We use high-precision CNC machining centers to hold critical bore tolerances within micrometers. Every product batch is validated using precision coordinate measuring machines (CMM) and undergoes high-pressure air and fluid leakage testing up to twice its maximum operating pressure.
We use high-grade Ethylene Propylene Diene Monomer (EPDM) rubber seals designed for automotive brake fluid applications. They are formulated to resist swelling, degradation, and cracking across a wide temperature range, from -40°C to +120°C, and are fully compatible with DOT 3, DOT 4, and DOT 5.1 brake fluids.
Standard lead times range from 30 to 45 days, depending on order size and custom requirements. MOQ requirements vary by part number, typically starting at 50 to 100 pieces per reference for standard items, and 500 pieces for custom developments.
Yes, as an IATF 16949 certified manufacturer, we can provide standard Level 3 Production Part Approval Process (PPAP) documentation. This includes material test certificates, process flow diagrams, failure mode and effects analysis (FMEA), control plans, and registration with the International Material Data System (IMDS).
Yes, we offer custom packaging and private labeling services. We can laser engrave part numbers, batch codes, or client logos directly onto cylinder bodies, and package them in custom boxes that meet your retail or industrial distribution requirements.
Heavy-duty master cylinders, clutch slave systems, and replacement cylinders designed for light commercial vehicles, passenger vans, and cargo trucks.
Provide your required part numbers, OEM cross-references, or technical specifications. Our engineering team will review your inquiry and respond with detailed pricing and delivery terms within 24 hours.
