Explore our premium range of OEM brake master cylinders, wheel cylinders, and calipers engineered to meet exact standard specifications.
Unlike disc systems, drum brakes utilize heavy-duty drum brake shoes pressed outward against a spinning drum. This setup is highly valued in heavy commercial transport, rear axles of light trucks, and electric vehicles due to its powerful self-energizing capability.
When the vehicle's hydraulic system activates, the wheel cylinder forces the brake shoe assemblies to expand. The friction material meets the inner drum surface, converting kinetic energy into thermal dissipation. In leading-trailing layouts, the rotation of the drum pulls the leading shoe directly into the friction face, creating a self-reinforcing braking torque. This dynamic reduces the pedal force required to achieve high deceleration, making it ideal for utility vehicles hauling large payloads.
Maintaining a stable friction coefficient (µ) across changing temperatures is critical. When heavy vehicles descend steep grades, friction faces can heat up to over 350°C. If the friction material lacks high thermal stability, brake fade occurs. As a premier industrial manufacturer, we design our friction linings with high-density fibers and heat-resistant resin matrices to guarantee reliable, consistent stopping power under high thermal loads.
Explore the composite materials and precision metal forming processes that define high-performance heavy-duty drum brake shoes.
We supply custom formulations for diverse operational environments:
The backing plate serves as the structural foundation of the brake shoe. We stamp ours using heavy-gauge structural steel (Q235B or equivalent) to prevent flexing under hard braking. The plates undergo electrophoretic deposition coating (E-coat) to pass a salt spray test, ensuring long-term resistance to rust, moisture, and road chemicals.
Delamination is a dangerous safety risk in friction systems. We bond our friction linings to the steel backing plates using high-temperature thermosetting adhesives, cured under precise pressure and heat. Every batch is tested to meet or exceed shear strength standards, keeping the friction material secure even under heavy pressure.
Operating from Wuhu, Anhui province, Wuhu Qiujing Auto Parts Co., Ltd. has manufactured premium automotive brake components since its establishment in 2007, built on a foundation of industry experience dating back to 1996.
Our 6,000-square-meter facility features automated stamping presses, high-capacity hydraulic bonding lines, and precision machining stations. Controlling the entire production process in-house allows us to maintain consistent quality and produce over 2 million units annually. We utilize advanced casting, precision metal stamping, and specialized compound mixing to deliver high-durability products for global buyers.
We source steel and friction raw materials directly from verified domestic suppliers, reducing material costs. Our integrated operations, automated production, and strategic location near major shipping hubs like Shanghai and Ningbo allow us to offer competitive wholesale pricing and reliable delivery schedules to customers worldwide.

Our factory manufactures a comprehensive range of hydraulic and friction components to service light passenger vehicles and commercial fleets.
Brake systems must meet strict safety and quality standards to ensure reliable performance on public roads worldwide.
Wuhu Qiujing operates in compliance with international quality management systems, holding certifications for GB/T19001-2016 / ISO 9001:2015 and IATF 16949:2016. These standards verify our traceability, material testing, and process control throughout our manufacturing line.
For European distribution, our components are manufactured to meet ECE R90 requirements, ensuring replacement parts perform within 15% of original equipment. In North America, we align with FMVSS 121 standards for heavy vehicles and public transit fleets. We also maintain compliance with national standard GB/T29490-2013, ensuring our designs and intellectual property are protected.
Understand the commercial variables, packaging standards, and lead times involved in bulk purchasing directly from our factory.
Our bulk pricing is tied directly to the cost of raw materials, specifically sheet steel and friction composites. We use transparent raw material indexing to offer fair, current pricing based on current steel and compound markets.
We provide OEM and ODM manufacturing services for custom parts. Standard inventory items feature flexible minimum order quantities, while custom orders require specific MOQs to cover the cost of development tooling, stamping dies, and prototype testing.
We pack orders securely in moisture-barrier VCI plastic bags and strong, export-grade corrugated cartons, stacked on IPPC-treated pallets. Our logistics team organizes shipping containers and coordinates with export customs agents to ensure efficient transit.
Brake systems require specific design features to handle different road conditions, temperature variations, and vehicle loads.
Vehicles operating in stop-and-go urban transit encounter frequent brake applications that prevent the system from cooling fully. Under these conditions, standard brake linings can experience glazed surfaces and noise. To prevent this, we formulate our friction materials with structural graphite and heat-dissipating brass fibers, keeping the friction face clean and maintaining consistent stopping power.
For heavy transport traversing steep mountain passes, persistent heat generation can cause thermal expansion of the brake drum, increasing the pedal stroke required to slow the vehicle. Our heavy-duty brake shoes feature low-compressibility linings that limit expansion and maintain positive, predictable pedal feel even during prolonged descents under load.
