This heavy-duty brake drum is cast from high-grade grey cast iron. The outer reinforced rib structure improves structural strength and heat dissipation, reducing the risk of thermal cracking under continuous heavy braking. The red anti-rust coating protects the surface during storage and shipment. The inner friction surface is precisely machined to ensure smooth, stable braking and low vibration. It fits most semi-trailer and heavy commercial truck axles. We support custom OE marking, different paint colors and bulk production according to samples or drawings.

FAQ
Q: What is red painted ribbed cast iron brake drum for semi trailer heavy duty axle used for?
A: It is a core drum brake spare part for semi-trailer axles. It works with brake shoes to generate friction to slow down and stop heavy trailers.
Q: What is the function of the outer ribs on this brake drum?
A: The ribs reinforce the drum body and expand heat dissipation area, helping release braking heat faster and avoid cracks.
Q: Does the red paint affect braking performance?
A: No, the red paint is only outer anti-rust protection, the inner friction surface is bare metal without coating.
Q: Can you supply matching brake shoes and wheel hardware?
A: Yes, we can provide compatible brake shoes, wheel studs and lug nuts together.
Q: Can you produce this brake drum with other paint colors?
A: Yes, we can customize black, dark green, red and other anti-rust paint finishes as requested.
