AL-KO 9-inch Commodore Brake Drum for Trailers

Genuine replacement AL-KO 9-inch trailer brake drums are engineered from heavy-duty ductile iron casting to fit standard mechanical and hydraulic backing plates seamlessly.

Product Description

Upgrade or service your trailer’s braking assembly with this high-grade AL-KO 9-inch Commodore Brake Drum. Manufactured by industry leader AL-KO International, these drums are engineered from premium S.G. casting (spheroidal graphite ductile iron), making them significantly stronger and more fracture-resistant than traditional grey iron castings. Whether you are operating a boat trailer, caravan, or utility box trailer, this drum ensures smooth, efficient, and legal stopping power across Australian highway networks.

This versatile hub drum is engineered to operate seamlessly with both 9-inch mechanical override backing plates and 9-inch hydraulic drum setups. Please note that this product comes fitted with heavy-duty wheel studs but does not include internal bearings, cups, or seals, giving you the freedom to utilise your preferred bearing configurations during setup.

Frequently Asked Questions (FAQ)

Q: Do these AL-KO brake drums include the internal trailer bearings and hub seals?

A: No. These genuine brake drums are delivered with the structural wheel studs securely installed but do not contain bearings, bearing cups, or hub dust seals. Matching Holden LM or Ford Slimline bearing kits must be purchased separately.

Q: Can I use this specific drum for an electric trailer brake backing plate?

A: This product is designed specifically to interface with mechanical override and hydraulic trailer backing systems. Electric drum brakes utilise a distinct internal machining profile on the inner face for electromagnet contact, which requires a specialised AL-KO electric hub drum variant.

Q: What is S.G. Ductile Iron Casting, and why does it matter for safety?

Use code with caution.A: Spheroidal Graphite (S.G.) ductile iron contains structural graphite nodules that maximise overall tensile strength, impact flexibility, and resistance to sudden fractures. This offers superior safety over cheap, brittle grey iron alternative drums on rough Australian regional tracks.
