The global automotive supply chain is undergoing structural shifts toward efficiency, parts consolidation, and stringent safety criteria. Citroen (as a core brand of Stellantis) relies on highly specific hydraulic architecture. The legacy of classic hydropneumatic systems (like the iconic LHM-fluid-based systems) has transitioned into high-pressure modern braking assemblies integrated with Anti-lock Braking Systems (ABS), Electronic Brakeforce Distribution (EBD), and Electronic Stability Programs (ESP).
For modern Citroen vehicle platforms, including the Stellantis CMP (Common Modular Platform) and EMP2 (Efficient Modular Platform 2), brake master cylinders and wheel cylinders must function within tighter safety margins than ever. Advanced driver assistance systems (ADAS) execute autonomous braking sequences, which demand immediate hydraulic pressure build-up. This places severe mechanical demands on the internal piston components, return springs, and elastomeric seals of the brake cylinder.
Providing a comprehensive suite of hydraulic components to meet all heavy-duty industrial and automotive requirements.
Dual-circuit designs featuring cast iron or anodized aluminum bodies for maximum pressure endurance.
Rear drum brake cylinders fitted with integrated pressure-conscious regulatory valves (PCRV).
Lightweight thermoplastic or metallic designs optimized for smooth, low-effort gear engagement.
Engineered for precise throw-out bearing actuation, ensuring minimal mechanical hysteresis.
Directs dynamic brake pressure distribution between the front and rear axles based on vehicle load.
Heavy-duty floating and fixed caliper designs engineered for rapid thermal dissipation and low drag.
Founded in 2007, with heritage and core engineering knowledge dating back to 1996, Wuhu Qiujing Auto Parts Co., Ltd. has established itself as an industry leader in manufacturing high-precision braking and clutch system hydraulics. Through continuous investment in advanced manufacturing, automated assembly lines, and digital testing laboratories, our facility supplies reliable solutions to distributors and OEM projects worldwide.
"Safety first" serves as our core operating directive. Under strict implementation of national and international quality systems, we run multi-level quality inspection gates from raw metallurgical casting analysis down to the final micron-level verification of rubber dust boots and primary seal cups.
An in-depth review of the metallurgy, surface treatments, and sealing technologies that define our high-reliability manufacturing process.
Brake cylinders function under severe pressures, sometimes exceeding 150 bar (15 MPa) during emergency stops. We utilize nodular cast iron (ductile iron) and lightweight anodized aluminum alloys. Ductile iron provides the high tensile strength required for commercial Citroen vehicles, such as the Citroen Jumper and Relay vans, which endure high payload-induced brake system loads. Aluminum designs, typical in passenger models like the Citroen C1 and C3, minimize unsprung mass, contributing to the vehicles' dynamic driving characteristics.
The weakest link in any hydraulic system is its seal. Our factory uses premium ethylene propylene diene monomer (EPDM) rubber compounds, which are compatible with DOT 3, DOT 4, and DOT 5.1 glycol-ether based brake fluids. These seals resist swelling and maintain their flexibility at extreme temperatures from -40°C to +120°C. This prevents seal degradation under heavy braking, which can lead to hazardous pressure loss.
Our internal cylinder bores are honed to a surface finish roughness (Ra) of less than 0.25 microns. This mirror-like finish reduces friction and extends the service life of the primary and secondary seals. Each cylinder undergoes automated pneumatic leak tests to ensure 100% seal integrity before shipment.
Professional, efficient, and integrated services built to secure and scale your automotive parts supply chain.
6,000+ m² facility, modern production tools, and an annual output exceeding 2 million units.
Advanced testing equipment ensuring rigorous performance metrics, backed by a 2-year warranty.
Standardized QC protocols and flexible batch production suitable for long-term distributor partnerships.
In-house R&D, manufacturing, QC, and sales teams ensuring smooth technical support and communication.
Our quality system is verified by international automotive testing bodies, meeting certifications including GB/T19001-2016 / ISO 9001:2015, IATF 16949:2016, and GB/T29490-2013.
We actively invest in product development to meet the evolving demands of modern vehicle platforms.
Transitioning from cast iron to high-strength aluminum alloys, reducing caliper and cylinder weight by 30%.
Adopting chrome-free surface coatings and fully bio-degradable, low-emission packaging.
Developing integration components for electro-hydraulic actuators used in hybrid and battery electric vehicles (EVs).
Deploying AI-driven optical scanners for real-time detection of micro-surface variations down to 0.05 microns.

We manufacture brake master cylinders and wheel cylinders for major Citroen platforms, covering models like the C1, C2, C3, C4, C5, Berlingo, Xsara, and Jumper. Our catalog is indexed with OEM cross-references, including PSA group part numbers, and standard aftermarket identifiers from databases like TecDoc (Ate, TRW, Bosch, and LPR cross-references).
Each brake cylinder undergoes a two-stage pneumatic leak test. First, a low-pressure test (0.02-0.05 MPa) checks for initial seal seating. Second, a high-pressure test (up to 16 MPa) simulates emergency braking loads. We also perform burst pressure tests on casting samples and environmental testing on rubber seals to verify heat and fluid resistance.
Cast iron housings are treated with an eco-friendly black electrophoretic coating (e-coat) or trivalent zinc plating. Our aluminum cylinders are anodized to protect the metal from atmospheric moisture and contaminants in the brake fluid. These surface treatments withstand over 240 hours of salt spray testing (ISO 9227 / ASTM B117) without showing red rust.
Yes. Our engineering department can work from technical drawings or physical OEM samples to reverse-engineer components. We verify the cylinder bore, piston stroke, thread pitches for the ports, and mounting bracket dimensions to ensure exact alignment and performance.
Our standard manufacturing lead time is 35 to 50 days, depending on production scheduling. For catalog items with existing casting tooling, the minimum order quantity is generally 50 to 100 units per reference. Custom development projects require higher MOQs to offset tooling costs, which we determine on a project-by-project basis.
Our Quality Management System (QMS) is certified to IATF 16949:2016 standards. This framework dictates strict control over our raw material sourcing, production tooling calibration, operator training, and traceability. Every batch of parts is marked with a laser-etched tracking code, allowing us to trace manufacturing details back to the raw material melt sheet.
