This brake drum is a precision-machined cast iron component designed specifically for SINOTRUK HOWO 6×4 heavy-duty trucks. It provides the friction surface for the brake shoes, converting kinetic energy into thermal energy to slow and stop the vehicle safely and reliably. Manufactured to exacting OEM tolerances, this drum ensures a perfect fit and reliable performance in all operating conditions.
The drum is cast from a high-carbon equivalent alloy iron, offering excellent thermal conductivity, wear resistance, and resistance to crack formation under severe braking. Its uniform wall thickness and optimized ribbing ensure even heat distribution, minimizing the risk of distortion and hot spots that can lead to brake fade or vibration. The friction surface is precision-ground to provide an ideal mating surface for new brake shoes, ensuring quick bed-in and consistent stopping power.
Investing in the genuine WG9112340006 brake drum ensures that your truck maintains its original braking performance, with reliable stopping power in all conditions. This component is the preferred choice for fleet operators and workshops that demand uncompromised safety, performance, and durability from their braking systems.

All values are based on OEM engineering drawings for this brake drum. Minor deviations may occur due to casting and machining tolerances.
This drum is cast from a high-carbon equivalent iron that provides excellent thermal conductivity, wear resistance, and resistance to crack formation under severe braking.
The ribbed outer design and uniform wall thickness promote even heat distribution, reducing the risk of hot spots and thermal cracking.
The inner surface is ground to a precise finish, ensuring optimal contact with brake shoes, rapid bedding, and consistent friction coefficient.
Each unit is dynamically balanced to minimise rotational vibration, ensuring smooth braking and reduced stress on wheel bearings.
The alloy and heat treatment provide exceptional resistance to cracking and distortion from repeated thermal cycling.
With its durable material and precision manufacturing, this drum delivers long-lasting performance, reducing brake overhaul frequency and lowering maintenance costs.
The brake drum is a safety-critical component that directly affects stopping distance, stability, and overall vehicle control. Using a counterfeit or substandard drum can lead to brake fade, cracking, and catastrophic failure. The genuine WG9112340006 drum eliminates these risks through OEM-grade materials, precision manufacturing, and rigorous quality control.
Key benefits of choosing the authentic component:
Deruna sources this brake drum directly from authorized manufacturers, subjecting each unit to a thorough quality inspection. We package each drum securely to prevent damage during shipping, so it arrives ready for installation.
Proper installation and regular maintenance are essential to maximize the service life and braking performance of this brake drum. Follow these best practices:
Before installation, clean the hub mounting face and inspect the drum for any shipping damage, cracks, or surface defects.
Always fit new, genuine wheel stud nuts or bolts when installing the drum to ensure correct clamping torque.
Tighten the wheel nuts in a cross-pattern to the torque value specified in the SINOTRUK HOWO service manual.
Clean the drum’s inner surface with brake cleaner and apply a thin layer of anti-seize to the hub pilot to prevent seizing.
Always refer to the SINOTRUK HOWO service manual for detailed wheel-end procedures, torque values, and wear limit inspections. Regular inspection of the drum’s inner diameter and thickness is essential to ensure safe braking performance.
This brake drum is compatible with a wide range of SINOTRUK HOWO heavy-duty trucks and commercial vehicles, including:
For models not listed, cross-reference your original brake drum part number with WG9112340006. This drum is designed to fit SINOTRUK HOWO axles with drum brake systems and 10-hole wheel mounting patterns. Please consult your vehicle’s service manual or a qualified technician to confirm compatibility.
This brake drum is a cornerstone of the SINOTRUK HOWO braking system, providing reliable, fade-resistant stopping performance in the most demanding heavy-duty applications. Its high-strength alloy construction, precision machining, and optimised heat dissipation ensure that your truck can stop safely and predictably, time after time.
By choosing the genuine WG9112340006 part, you protect your vehicle and its occupants from the dangers of inferior aftermarket alternatives – poor heat dissipation, cracking, and unpredictable braking.
