A few years ago, we were worried about the increasing loss of quality and increasing complaints from imported drums.

We decided to make a better 10-inch drum brake to ensure electric brake drums were first class and we could take ownership of a quality product. We also gained the opportunity to make a variety of uniquely studded drums within 48 hours.

What makes Couplemate Electric Brake Drums Different?

Our engineers discovered a little talked about a problem called porosity as a major cause of braking inefficiencies.

Porosity is a series of holes in a casting that causes lower brake shoe adhesion.

In simple terms, a porous surface will have less braking resistance than a non-porous surface.

The best way to explain how to remove air from steel is to understand how air is expelled from concrete. The process of shaking or vibrating the tooling containing a drum casting effectively removes air bubbles thereby greatly reducing porosity.

Further, during the machining process, our craftsman is on the lookout for a sign of porosity. When found, drums are rejected, scraped and returned to the furnace. As a result, you can be assured the drums you have purchased have undergone rigorous testing and inspecting processes.

Today we sell, Australian made Couplemate 10? brake drums and Alko 12? brake drums to the RV markets and for retail consumption.

Trailer and caravan electric brakes have a variety of problems—not just worn bearing journals. The only thing you can do with worn outer bearing journals is to replace the drum. (Store Locator)

The fix will last until you get into the next big town without the need for an emergency tow. Limit your speed to 60 km, and hobble into town, Also, be on the lookout for a worn magnet face, both on your magnet and on your inner drums. Worn surfaces will decrease braking efficiency by about 70%.

When you’re out in the Australian outback, your vehicle and caravan trailer have to deal with a lot more than just a bumpy ride. The temperature outside is reasonably hot, and most parts of your car, especially, the suspension, the brakes, ball coupling and the springs, are subject to large amounts of physical stress.

Please note: Wheel nuts not included.

We also ship products to New Zealand via Australia Post Air Express.
