Easily Upgrade Your Current Caravan Axle to Off-Road Brakes

Electric brakes are reliable, safe, and easy to maintain.

Similar to backing plates seen on cars, electric drum brakes use backing plates to apply brakes. Even better, 10″ drum brakes are one of the most common brake systems on Australian trailers and caravans, meaning that finding spare parts is easy.

Couplemate™ 10-inch Conversion Kits are available in multiple stud patterns, such as 6-Stud Landcruiser and 5-Stud Ford.

For increased 4WD performance, you can upgrade to Off-Road Brakes.

Why do people like electric trailer brakes?

Along with being cheaper than disc brakes, people like them because they:

  • Prove highly effective, safe braking in all-terrain conditions.
  • They are low maintenance and require no technical knowledge.
  • Spare parts are relatively cheap and easy to find anywhere in Australia.
  • Use brake controllers that allow you to adjust power output if needed easily.

Conversion Kit Contents

The Couplemate™ Conversion Kits are designed to easily convert your current axle to electric brakes.

When you buy this conversion kit, you will receive: 

  • 2 x 10″ Brake Drums (incl. wheel nuts)
  • 2 x 10″ Electric Backing Plates (incl. mount nuts)
  • 2 x Japanese Bearing Kits (incl. bearings, seal and grease caps)
  • 2 x Weld Rings

What are the Weld Rings for? Weld Rings get welded onto your axle and allow you to mount your backing plate.

What Do You Need To Know?

Brakes are an important part of road safety, so it’s important that you get the right parts for your system.

Couplemate™ brakes this down in three, easy steps:

Step 1: Check your wheels.

Check your stud pattern to ensure the brake drum will fit your existing wheels.

The three most common are:

  • Ford (5 x 114.3mm)
  • 5 Stud Landcruiser (5 x 150mm)
  • 6 Stud Landcruiser (6 x 139.7mm)
What is P.C.D.

Easily work our your stud pattern by measuring stud centre to stud centre on the two closest studs (“S”).

If you’re looking to match your trailer wheels to your tow vehicle, now’s a great time. Just make

Step 2: Check your bearings.

This 10″ conversion kit suits Ford Slimline (SL) bearings.

  • Inner Bearing: LM68149/10
  • Outer Bearing: LM12749/10

Most DIY enthusiasts resort to this hands-on approach, though sometimes bearing information is in your caravan owner’s manual.

Step 3: Check your axle.

Firstly, examine the bearing profile to determine whether a marine or electric turn weld ring is required for your axle.

Not sure? Measure from the tip of the axle to the back shoulder.

  • Electric Turn: 128mm
  • Marine Turn: 115mm

If you have a marine turn, use square. If you use an electric, use a round.

What’s Good About Couplemate™ Drums?

Our engineers successfully addressed a critical issue, “porosity,” significantly contributing to braking inefficiencies.

Porosity refers to the presence of small holes within a casting, which reduces brake shoe adhesion. Essentially, a porous surface exhibits lower braking resistance than a non-porous surface.

The most effective method to eliminate air from steel is analogous to expelling air from concrete. By subjecting the tooling containing a drum casting to shaking or vibration, we effectively eliminate air bubbles, significantly reducing the occurrence of porosity.

Furthermore, our skilled craftsmen meticulously scrutinise the machining process for any signs of porosity. When identified, drums are promptly rejected, discarded, and returned to the furnace. This stringent quality control ensures that the drums you acquire have undergone rigorous testing and inspection processes, guaranteeing their performance and reliability.
