Product Q&A

Q:Are truck brake drums balanced?

Yes. High-quality brake drums are dynamically balanced to reduce vibration, noise, and uneven wear during braking.

Q:What materials are truck brake drums made of?

Most truck brake drums are manufactured from high-quality cast iron (HT250 / HT300) or ductile iron for higher strength and crack resistance. These materials provide excellent heat dissipation and wear resistance.

Q:What are the common sizes of truck brake drums?

Popular sizes include 16.5 inch, 15 inch, 420 mm, and 410 mm. Sizes vary by axle type and market standards (SAE / ECE).

Q:What is the difference between front and rear brake drums?

Front brake drums are used on steer axles with lighter loads. Rear brake drums are used on drive axles requiring higher load capacity and wear resistance.

Q:What is the service life of a truck brake drum?

Service life depends on load conditions, road and climate environment, and driving habits. On average, truck brake drums last 200,000-400,000 km under normal conditions.
