Frequently Asked Questions
A brake drum is a rotating cylindrical component attached to the wheel hub. When the brake pedal is pressed, hydraulic pressure forces brake shoes against the inner surface of the drum, creating the friction necessary to slow or stop the vehicle.
Depending on the application, high-quality cast iron is used for its strength and heat resistance, while aluminum alloys or composite materials are used to reduce unsprung weight and improve efficiency in performance vehicles.
Key signs include vibration or pulsation during braking, visible scoring or cracks on the drum's internal surface, a noticeable reduction in braking performance, or uneven wear patterns.
Standard solid drums are single-piece designs for light-duty use. Vented drums feature cooling fins between two walls to improve heat dissipation, making them essential for heavy-duty trucks and high-performance braking.
Yes, we provide comprehensive OEM & ODM services. We can manufacture brake drums according to your specific technical drawings or samples, including custom sizes, surface treatments, and brand logo engraving.
Under normal conditions, they last between 100,000 and 150,000 km. However, lifespan in industrial or agricultural machinery varies based on load weight, frequency of braking, and the quality of routine maintenance.
