Electric Brake Conversion Kit
The electric brake conversion kit converts an unbraked trailer into an electric braked trailer or camper using the existing axle.
Couplemate sells only the highest quality electric backing plates, Japanese bearings and Australian made Couplemate Brake Drums.
What make Couplemate Drums Different?
Our engineers discovered a little talked about 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 are on the lookout for 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.

How to select the correct weld ring?
Firstly, examine the bearing profile to determine whether a marine or electric turn weld ring is required for your axle
- An electric turn measures 128mm for slimline and 140mm for parallel bearings, from the top of the axle to the back shoulder
- A marine turn measures 115mm for slimline bearings from the tip of the axle to the back shoulder
(from the image) Use the square hole weld ring for marine turn and the round hole for electric turn axles.
Select your weld ring from the drop-down menu. Note: Electric weld rings are not suitable for hydraulic brakes.
Activate the caravan or trailer brakes from a brake controller in the tow vehicle or some states, located on the trailer chassis.
Standard highway magnets are installed in all conversion kits; however, Al-ko makes a perfect off-road magnet as an optional extra. A wide selection of 10″ drums is available including 5 and 6 stud Landcruiser and Landrover.
Disc brakes are not available to be electrically braked when installed on boat trailers. Mechanical disc brakes are suited to trailers under 1500kg. Alternatively, hydraulic disc rotors are suited to boat trailers over 2000kg.
Brake Kit Install method #1
When fitting your electric weld ring, ensure there is pressure against the rear shoulder and quickly tack the four corners. You are now ready to weld the weld ring into place.
Brake Kit Install method #2
- Bolt the weld ring to the backing plate
- Slide the backing plate onto the axle
- Install the drum onto the axle and tighten (no grease in the bearings at this stage)
- Pull the backing plate into the drum and then tighten the brake shoes, so they firmly engage the drum
- Tap the backing plate, so it is Concentrix with the drum
- Tighten the shoes against the drum firmly
- Tack the backing plate on the four corners
- Remove the drum
- Finish the weld and proceed to do the same at the other end of the axle
Trailer parts include:
- Electric Backing plates x 2
- 7/16″ Nylocks for backing plates x 8
- Slimline or Parallel bearings x 2
- 10″ Electric Drum x 2
- Weld rings x 2
- Wheel nuts
Hydraulic disc brakes are superior in marine applications. Electric braking plates and drums rust out quickly when exposed to salt water. Fresh water is not as corrosive however, hydraulic brakes are still preferred in this environment.
