Brake Drums

Hub Drums for Trailers & Caravans

Drum brakes are an essential part of trailer brake systems. In Australia, it’s popular for caravans, campers and general-purpose box trailers to be equipped with Brake Drums.

What’s great about our 10″ drums is that they suit a variety of backing plates. Whether you have electric, hydraulic, or mechanical brakes, Couplemate™ drums are high-quality and fit for purpose.

Our drums are available in popular stud patterns, such as Landcruiser, Ford or Holden HT, as well as niche patterns like F250, Mercedes, Jeep, and many more.

If you’re not sure what your stud pattern is, read our quick guide on how to calculate Stud P.C.D.

How Do Drum Brakes Work?

Drums use a backing plate, which causes friction on the inner surface of your drum through a brake shoes. When you apply brakes, these shoes engage and press against the rotating brake drum. This is what causes your trailer to stop!

What’s great about drum brakes is their simple design. From finding spare parts to troubleshooting, most people can do it easily with little experience.

What trailer uses these hubs?

Australian legislation states that all trailers, caravans, and campers must have brakes fitted once the ATM exceeds 750kg.

As such, 10″ drums are used on on trailers with an ATM from 750kg up to 2000kg. The type can be mechanical, hydraulic, or electric and are required on one axle.

Genuine Couplemate™ Brake Parts

Couplemate™ has been manufacturing our brake drums in Australia since 2017. Since then, they’ve become an industry favourite that is found on many popular caravan and trailer brands in Australia.

Couplemate™ engineers addressed a significant problem with lower-quality caravan drums called porosity.

Porosity is a series of holes or air bubbles in a steel casting that causes lower brake shoe adhesion, which we discovered to be a significant cause of braking inefficiencies.

All Couplemate™ products must pass rigorous testing and inspection before, during, and after manufacturing. In the rare event that our developing Engineers are unsatisfied with the quality, the drums are scraped and never made available.

This means that all Australians can feel confident on the road, knowing that their 10″ trailer brake drums will provide consistent and safe braking.
