Our testing has found electric drums are not magnetised when an energised magnet engages a drum for several days. However, by turning the drum and applying a magnet to the surface of the drum, a different result is achieved.
Some trailers and caravans are very long and therefore incur more voltage drop than usual. Measure the voltage drop from the battery to the last electric magnet.
In our opinion, bearing buddies can cause grease contamination of brake shoes when overfilled. Couplemate has concluded that bearing buddies are unsafe to be used in conjunction with drums brakes and should be immediately replaced with conventional or grommeted grease caps.
Caravans and some heavier campers are continuing to experience braking problems in mountainous regions. Overheating drums are a major concern for owners as they strive to improve their braking. Couplemate have deconstructed and simplified electric braking problems.
“I have no idea what PCD is nor do I know how to calculate it?”….is an answer we hear frequently from customers. Technically, Pitch Circle Diameter (PCD) is the diameter of the circle which passes through the centre of the wheel studs, wheel bolts or wheel rim holes.
Here is a simple test for your electric drums to test to prove polarisation. Point your trailer coupling facing north or south. Residual magnetism can be excess positive ions(North Pole) or excess negative ions (South Pole).
Learn how dirt roads destroy Electric Brakes. Unsuspecting caravan owners discover their electric braking systems and electric drums are being rendered defective by vibrations transferred to braking systems by corrugated roads.
“I do not think I really need electric brakes on my camper as it is pretty light.” is a comment I get all the time. This one scared me enough to put disc rotors and brakes on my boat trailer. I should have known better, and I should have done it years before, but I didn’t. How electric brakes work. Allow the experts at Couplemate to solve your braking problems. Simple solutions to increase braking power.
The correct method using 5mm cable is to run a cable down EACH chassis rail and connect each magnet independently. This type of connection is called parallel.

The Coupleamte Caravan Hubodometer measures the kilometres travelled towing your gear. Distance between service events like bearing adjustments, tyre wear, shackle bolt and plate replacement can be measured.
Dee Shackles and Bow Shackles will be mandatory when rule changes come into effect in 2019.
Early Alko offroad couplings used a locking ring to enable the coupling to be connected. Learn how to connect this coupling correctly and not brake the locking ring.
Understanding Safety Chains can be difficult and confusing. The experts at Couplemate have tried to make it simpler with this animated video.
