10-inch AL-KO Electric Brake Conversion Kit
The 10-inch caravan electric brake conversion kit makes it easy to convert an unbraked or disc-braked trailer axle to electric drum brakes.
Electric brakes are reliable, safe, and easy to maintain. Like the backing plates on cars, electric drum brakes use backing plates to apply the brakes. Even better, 10″ drum brakes are one of the most common brake systems on Australian trailers and caravans, meaning finding spare parts is easy.
AL-KO 10-inch Conversion Kits are available in multiple stud patterns, such as 6-Stud Land Cruiser 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 let you easily adjust power output if needed.
Conversion Kit Contents
The Couplemate™ Conversion Kits are designed to convert your current axle to electric brakes easily.
When you buy this conversion kit, you will receive:
- 2 x 10″ AL-KO 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 (Note: Standard weld ring is 45mm round hole to fit over seal journal – Most Popular)
What are the Weld Rings for? Weld Rings get welded onto your axle and allow you to mount your backing plate.
What Parts Do You Need?
Bearing Profile
This information is sometimes outlined in your owner’s manual or kept on file by the original caravan/trailer manufacturer. However, most customers resort to a hands-on approach.
To find your bearings, separate your hub from your axle and pull out both bearings. Quality bearings will always have their bearing number engraved on them, as shown in the example image:
An example of where to find a bearing number on trailer or caravan bearings is
Holden LM Bearings (750kg)
Ford SL Bearings (1450kg)
Axle Weld Rings
First, examine the bearing profile to determine whether your axle needs a marine or electric turn weld ring.
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 a square. If you use an electric, use a round.

Stud Pattern & Stud Thread
Understanding your Stud Pattern (PCD) is crucial when buying spare parts, as it ensures that your new drum will fit your existing trailer wheel.
The best way to work out your stud pattern is by measuring from stud centre to stud centre on the two closest studs (see “S” on the diagram). Once you have this measurement, use our Stud Pattern chart (available here) to work out your PCD.
How To Install Electric Brakes
Method One
When fitting your electric weld ring, ensure it’s pressed against the rear shoulder, then quickly tack the four corners. You are now ready to weld the weld ring into place.
Couplemate uses a tool to firmly secure the weld ring onto the axle shoulder before tack welding.
Method Two
- Bolt the weld ring to the backing plate
- Slide the backing plate onto the axle
- Install the drum onto the axle and tighten it (no grease in the bearings at this stage).
- Pull the backing plate into the drum and tighten the brake shoes to firmly engage the drum.
- Tap the backing plate so it is concentric with the drum
- Tighten the shoes against the drum firmly
- Tack the backing plate to the four corners
- Remove the drum
- Finally, finish the weld and repeat at the other end of the axle.
Brake Conversion FAQ & Installation Guide
10-inch AL-KO Electric Brake Conversion Kit
What You SHOULD Do (Dos)
- ✓ Check backing plate orientation: Ensure you install the left-hand (LH) and right-hand (RH) backing plates on their correct sides; the primary shoe (shorter lining) must face the front of the trailer.
- ✓ Bed in your new brakes properly: Perform 20 to 30 smooth stops from roughly 50 km/h during your first drive to properly seat the new shoes against your 10-inch AL-KO drums.
- ✓ Use correct gauge automotive wiring: Run a minimum of 4mm or 5mm twin-core automotive cable directly to the backing plates to prevent voltage drops across your **electric brake system**.
- ✓ Solder and seal your connections: Always solder your wire joins and insulate them with marine-grade heat shrink to shield the connections from moisture and road grime.
What You SHOULD NOT Do (Don’ts)
- ✗ Do not contaminate the brake linings: Keep all grease, oil, and workshop solvents completely away from the brake shoes and magnet faces during installation.
- ✗ Do not over-tighten the shoe adjuster: Avoid locking up the drum when setting your initial manual adjustment; leave just enough room for a very slight, even drag when turning the wheel by hand.
- ✗ Do not forget the breakaway system: Never complete an electric conversion on trailers over 2,000kg ATM without installing a compliant breakaway battery kit to meet Australian design rules.
- ✗ Do not submerge standard electric plates: Refrain from launching boats or submerging these backing plates deep into water unless you have specifically purchased the specialised AL-KO marine-ready electric variant.
