Explore our high-performance components manufactured for major automotive brands including Toyota, Isuzu, Mitsubishi, Nissan, and Daihatsu.
Within automotive active safety architectures, the hydraulic system acts as the core multiplier of deceleration force. Every Brake Master Cylinder and Brake Wheel Cylinder operates as a primary pressure containment vessel, demanding flawless metallurgical integrity and strict micro-machining tolerances. At Wuhu Qiujing Auto Parts Co., Ltd. (founded in 2007, with deep sector expertise dating back to 1996), our manufacturing processes prioritize physical reliability to prevent internal seal bypasses or fluid leakage.
Our component design processes integrate structural analysis to counter long-term high-pressure fatigue. Standard master cylinders must withstand fluid pressures exceeding 15 MPa without body expansion or structural failure. We employ anodized aluminum and grade GG25 pearlite cast iron alloys to guarantee uniform wall thickness, minimal coefficient of thermal expansion, and resistance to environmental corrosion. For heavy-duty operations, including systems supporting vehicles like the Toyota Hilux and Isuzu trucks, these specifications form the foundation of our product lines.
Delivering precision performance for passenger cars, light commercial vehicles, and heavy transportation systems.
The core component that converts mechanical pedal force into hydraulic pressure. Utilizing precision-honed cylinder bores and premium EPDM seals to prevent fluid bypass under extreme temperature fluctuations (-40°C to +120°C).
Engineered for drum brake configurations, translating line pressure into outward force. We employ anti-dust boots and hard-anodized pistons to protect components from water intrusion, salt spray, and abrasive road debris.
Engineered for manual drivetrain actuation, providing a smooth clutch pedal feel and reliable pressure delivery. Resistant to degradation from standard glycol-based brake fluids (DOT 3, DOT 4, and DOT 5.1).
Self-adjusting slave cylinders designed to operate in high-vibration clutch bell housing environments, delivering consistent shift performance over long lifetimes.
Crucial components for dynamic hydraulic balancing. Prevents rear-wheel lock-up during hard deceleration by controlling rear line pressure in relation to load distribution.
Precision-cast calipers featuring optimized thermal dissipation pathways and surface finishes. Designed to prevent caliper binding, piston sticking, and uneven pad wear under heavy loads.
Operating a dedicated 6,000 m² advanced manufacturing facility, Wuhu Qiujing Auto Parts integrates automated machining centers, modern casting lines, and multi-stage testing benches to maintain high production quality. From initial raw materials to finished hydraulic components, our production pipeline minimizes physical variation and increases throughput efficiency.
Our machinery suite includes high-precision CNC lathes, automated coordinate measuring machines (CMM) for dimensional verification, and low-tolerance honing equipment. Every component undergoes pressurized verification tests before packaging, checking for microscopic surface variations and seal integrity. This automated inspection framework supports our large-scale output capabilities, serving distributors and parts suppliers globally.
Wuhu Qiujing utilizes integrated manufacturing processes to control costs and maintain quality standards.
Operated since 2007. Direct oversight of core production costs, flexible scheduling, and custom engineering capability for specialized global requests.
Every batch undergoes structural testing. We support our hydraulic lines with a two-year after-sales performance warranty.
Automated casting and machining lines ensure dimensional consistency from the first to the millionth unit, reducing field return rates.
Experienced R&D, manufacturing, quality assurance, and international logistics teams cooperate to manage customer requirements from drawing to delivery.
The global transition to electrification and advanced driver-assistance systems (ADAS) alters the requirements placed on hydraulic brake systems. Traditional vacuum boosters are replaced by electromechanical brake boosters and integrated electro-hydraulic braking systems (EHB). This requires hydraulic cylinders to handle pressure spikes faster and resist wear during cooperative regenerative braking sequences.
Our future development roadmap addresses these industry changes through targeted engineering:
Integrating electronic actuations and lightweight alloys by 2026.
Developing pressure chambers for high-frequency electro-hydraulic braking.
35% weight reduction achieved over traditional gray iron castings.
Our production facilities maintain global certifications, securing traceability and product consistency for global markets.
