Frequently Asked Questions

Q: What does a trailer hub drum with electric brakes do? A: The hub drum provides the wheel mounting surface and rotating brake surface, while the electric brake assembly applies braking force to help slow the trailer. Together they form the wheel-end braking and mounting assembly on the axle.

Q: How should I verify fitment? A: Confirm the axle rating, the wheel bolt pattern, and the brake drum size against your existing drum or axle specification before ordering. Also compare the existing part number and the complete axle or trailer model designation where available.
