- Crack resistance— the optimized casting structure minimizes internal stresses, which significantly extends the service life of the part.
- Exact OEM standard dimensions— installation takes place without additional adjustment, and this saves time and labor costs during repairs.
- Balanced mass— eliminates vibrations at high speed, ensuring smooth running and comfortable control.
- Strict quality control— each drum is tested for compliance with geometry, hardness and balancing before shipment.

Related Components
When servicing the brake system, we also recommend paying attention to related transmission parts. In particular,bearing NUP309E (AZ9003320309)— cylindrical roller bearing, which is installed in the HW gearbox (Sinotruk). Timely replacement of the transmission bearing is just as important as the replacement of brake components, since wear of one component inevitably affects the performance of the entire chassis.

Customer case: how Sinotruk WG9231342006 brake drum solved the problem of a vehicle fleet in Central Asia
One of our regular partners is a transport company from Uzbekistan that operates a fleet of 120 Sinotruk HOWO trucks. Previously, they purchased brake drums from local resellers, but faced frequent complaints: the drums became cracked after 40,000 km.
After switching to direct deliveriesbrake drum WG9231342006 SinotrukFrom Mettlead the situation has changed dramatically. The average service life of a part increased to 90,000–100,000 km, the number of unscheduled repairs decreased by 60%, and the total cost of maintaining the brake system decreased by 35%. In addition, stable delivery times (14–18 days to Tashkent) allowed the company to switch to a planned maintenance system instead of emergency purchases.
“We have finally found a supplier we can trust. The quality of the drums is consistent from batch to batch, and the price allows us to remain competitive in the market",” noted the head of the company’s purchasing department.
Frequently asked questions about Sinotruk WG9231342006 brake drum
What material is the WG9231342006 brake drum made of?
The drum is cast from high-strength gray cast iron HT250. This alloy optimally combines hardness, heat dissipation ability and resistance to cracks under cyclic thermal loads. That is why the part retains its working geometry throughout its entire service life.
Can this drum be installed on HOWO A7 and SITRAK at the same time?
Yes. Sinotruk WG9231342006 brake drum is suitable for HC16 series rear axle models and similar ones. However, before ordering, we recommend that you check compatibility by VIN or axle number to avoid selection errors.
What is the recommended brake drum replacement interval?
Under normal operating conditions (road transport without constant descents), the drum resource is 80,000–120,000 km. However, if the thickness of the drum wall has reached its limit or deep grooves appear on the working surface, the part must be replaced regardless of the mileage.
How does your drum differ from non-original analogues on the market?
The main difference is compliance with OEM specifications for alloy chemistry, geometry and balancing. Many cheap analogues use recycled cast iron with impurities, which leads to premature cracking. The WG9231342006 brake drum from Mettlead is 100% inspected, including runout and hardness testing.
How to properly store a brake drum before installation?
Store the part in a dry place, preferably in the original packaging. The working surface is coated with an anti-corrosion compound at the factory, but during long-term storage (over 6 months) it is recommended to additionally treat it with preservative oil. Before installation, be sure to remove the preservative and check the surface for rust.
