Explore our industrial grade Brake Master Cylinders and Brake Wheel Cylinders manufactured to meet or exceed Tier-1 international standards.
With roots tracing back to 1996, our founder envisioned a manufacturing hub that would redefine the safety and durability standards of hydraulic braking components. Officially established in 2007, Wuhu Qiujing Auto Parts Co., Ltd. has evolved into an industry-leading source factory specialized in manufacturing premium automotive brake parts.
Operating from a state-of-the-art 6,000 m² facility, we are fueled by the synthesis of professional craftsmanship and highly standardized automation. Our plant is strictly certified under IATF 16949:2016 and GB/T19001-2016/ISO 9001:2015 quality systems. This ensures every brake master cylinder, wheel cylinder, clutch master cylinder, and caliper is subject to extensive pressure and stress testing to satisfy strict global road conditions.
A broad catalog covering core hydraulic and mechanical braking assemblies engineered for international passenger cars and commercial vehicles.
Combining mechanical precision and agile logistics to ensure consistent delivery, minimal lead times, and extreme quality reliability.
We deploy automated high-precision CNC boring machines and robotic inspection arrays. Tool wear monitoring guarantees bore tolerances stay within ±0.02mm, optimizing hydraulic pressure integrity and stopping piston drag.
Every single cylinder is 100% air-leak and high-pressure fluid-pressure tested before packaging. Our quality protocols comply fully with IATF 16949 requirements, keeping post-sale failure rates under 150 PPM.
Located within China's major automotive industrial zone, we maintain deep supply integrations with local premier casting mills, high-grade EPDM rubber developers, and raw steel refineries to protect against market shortages.
How Wuhu Qiujing Auto Parts is preparing for next-generation mobility: Electrification, lightweight alloys, and intelligent braking actuators.
Modern electric drivetrains demand brake components capable of dealing with the high-stress cycles of regenerative braking. Our research focus is on developing seals with lower friction coefficients and zero-drag piston returns.
Reducing unsprung mass is crucial to improving EV range. We are shifting toward high-strength anodized aluminum alloys, shaving up to 40% of the weight compared to traditional cast-iron cylinders while retaining burst-pressure thresholds.
To resist corrosive road salts, all master and wheel cylinders are treated with anti-corrosion zinc-nickel coatings, surviving up to 480 hours of salt spray testing (ISO 9227) without showing red rust.
Solving procurement, pricing, and technical pain points for Tier-1 buyers, wholesale distributors, and global fleet operators.
By cutting out agents, we offer direct-factory rates, giving wholesale distributors room to achieve higher operating margins. Customized packaging is available to support local brand building.
We maintain an extensive OEM parts database covering thousands of vehicles. Our engineers quickly cross-reference OEM numbers (Toyota, Isuzu, GM, Ford, Nissan) to ensure 100% mechanical drop-in compatibility.
We adapt our production planning to your shipping schedule, offering flexible MOQ limits for trial containers. This helps new market entries test the demand without running up high inventory costs.
Securing cross-border shipments through certifications, localized logistics expertise, and transparent material reports.
We provide full documentation, including Mill Test Certificates, REACH chemical safety compliance, and ISO 9001:2015/IATF 16949 logs, allowing for fast customs clearance at major global ports.
Our internal testing matches US FMVSS 105/135 and European ECE R90 regulations. Piston return springs, EPDM seal elasticity, and cylinder wall finishes are tested under temperature extremes from -40°C to 120°C.
Customers working on custom applications get direct support from our engineering team, with fast turnaround times for CAD designs and metal prototype evaluation.
We maintain strict quality control through adherence to international standards: GB/T19001-2016/ISO 9001:2015, IATF16949:2016, and GB/T29490-2013.

Each cylinder undergoes 100% pneumatic sealing verification and high-pressure oil testing (exceeding 10 MPa) to ensure zero fluid leaks. Tests are calibrated to meet or exceed IATF 16949 and ISO 9001 standards.
Yes. Our engineering department can convert custom CAD models or sample components into production-ready designs. We provide metal alloy composition analysis and rapid physical prototyping.
We use multi-station CNC boring machines equipped with automatic tool wear compensators. This keeps bore diameter and cylinder circularity within strict ±0.02mm limits.
We exclusively use premium EPDM rubber formulation seals. These offer excellent resistance to corrosive glycol-based DOT 3, DOT 4, and DOT 5.1 brake fluids, even at temperature extremes from -40°C to 120°C.
Standard tooling and production setups for catalog products generally range from 30 to 45 days. Lead times can vary depending on materials availability and order size.
We apply an advanced black electro-deposition coating (e-coat) or acid-zinc plating. This provides strong resistance against road debris, oxidation, and humidity.
