Explore our top-tier selection of brake and clutch cylinders designed for global automotive architectures.
An authoritative whitepaper on materials engineering, dimensional metrics, and manufacturing standards for rear brake wheel cylinders.
The OEM Uh71-26-610 is a high-duty rear brake wheel cylinder, primarily integrated into the drum brake assemblies of utility trucks and mid-sized pickups, notably the Mazda B-Series (B2500, B2600, B2200) and corresponding Ford Ranger platforms. As a critical actuator, this component transforms hydraulic line pressure into mechanical force, expanding the brake shoes against the drum to decelerate the vehicle safely.
To withstand extreme operating conditions, the cylinder bore is honed to a strict tolerance profile (micrometer level) to minimize friction and prevent fluid bypass. Additionally, the interior is treated with anti-corrosive, wear-resistant coating schemes to resist the aggressive chemical environment of glycol-ether-based DOT 3, DOT 4, and DOT 5.1 brake fluids.
Reliability in commercial-grade drum braking relies heavily on materials science. The Uh71-26-610 utilizes high-strength HT250 Grey Cast Iron, which provides excellent thermal conductivity and dampens mechanical vibrations. In lighter application profiles, premium anodized aluminum cylinders are utilized to reduce unsprung weight.
The internal seals are formulated from Ethylene Propylene Diene Monomer (EPDM) rubber. Unlike standard nitrile polymers, our proprietary EPDM compound is resilient against degradation from temperature peaks (up to 150°C) and stays elastic at sub-zero temperatures (-45°C), ensuring no pressure drops occur during cold climate startups. Anodized pistons are paired with dust caps to exclude road dust, mud, and water, protecting the sliding surfaces from scoring.
Our state-of-the-art manufacturing lines cover all aspects of automotive hydraulic control.
We are a professional brake system parts manufacturer and supplier, mainly including brake master cylinder, brake wheel cylinder, clutch master cylinder, clutch slave cylinder, etc. The founder has been deeply engaged in automotive brake parts since 1996. Through industry experience and production technology, the factory has now developed dozens of models and thousands of products to ensure that they are suitable for different models and meet different road requirements. The products have GB/T19001-2016/ISO 9001:2015, IATF16949:2016 quality system certification.
"Safety First" is the core manufacturing concept of our facility.
Actively promoting the corporate spirit of "Integrity, Innovation, and Efficiency".
Discover how Uh71-26-610 fits into regional logistics, mining vehicle operations, and commercial supply lines globally.
In Southeast Asia and regional China, Mazda B-Series platforms function as core workhorses for agricultural transport. These vehicles operate under payload levels that push limits, traveling on unpaved roads and steep slopes. Our Uh71-26-610 wheel cylinders are optimized to prevent thermal fading, maintaining braking safety even under heavy agricultural cargo loads.
From the Andean passes in Chile to the humid regions of Brazil, utility fleets contend with extreme altitudes and corrosive salt-air conditions. Our wheel cylinders feature an electro-deposition coating that achieves over 240 hours of salt spray protection, preventing rust and sticking pistons in high-humidity areas.
For wholesale distributors across the EU and UK, component traceability and certifications are essential. Wuhu Qiujing satisfies these standards by providing complete batch tracking, IATF 16949-compliant test sheets, and retail-ready packaging designed for rapid fulfillment cycles.
The automotive braking landscape is adapting to stricter environmental and safety standards. Our R&D department continues to optimize hydraulic components to meet these changes, focusing on three key areas:
Why Tier-1 distributors, wholesalers, and purchasing departments trust Wuhu Qiujing Auto Parts.
We operate our own facility featuring a 6,000+ m² production layout, supporting direct factory quotes and streamlined delivery schedules.
Equipped with precision testing benches to monitor hydraulic performance, backed by a comprehensive two-year after-sales warranty.
Consistent manufacturing tolerances and automated quality audits ensure long-term, reliable operations for bulk contracts.
Our engineering, quality control, and export teams cooperate to provide rapid custom development and dispatch handling.
Our products carry global certifications to meet strict regional regulatory requirements.
Insightful strategies for industrial buyers to optimize inventory turnover and secure high-value pricing models.
Sourcing pricing for wheel cylinders is dependent on raw material indexes for iron ore, copper, and polymer bases. At Wuhu Qiujing, we mitigate price fluctuations through raw material reserves and efficient energy use, ensuring long-term price stability for our distribution partners.
