Electric brake shoes are not self-aligning.
When installing new brake shoes, adjust the brake shoes until they close, and the wheel is locked to prevent turning.
The factory setting is 13 turns from fully closed, but you may need more or less when replacing new shoes. Use 4mm trailer cable on the parking brake.
Do not wire electric brakes across the axle. Rundown each chassis rail separately to reduce voltage losses.
If existing wire run across the axle, install another pair of cables or install a larger cable to counter voltage loss.
Why can’t I run the electric cable across my axle?
Click this link to check the correct cable size for your installation
- Rundown each chassis rail = 6mtr @ 6.4 Amps per pair of magnets = 5.62mm cable size
- Run down the chassis trailer (inside) = 6 meter + 2 meter (8mtr) @ 6.4 Amps per pair of magnets = 7.5mm cable size
To escape voltage drop, run your cabling down the chassis rail. How electric drum magnets can become electrically ineffective
Cable sizes can be confusing because there are two standards used.
- Electric Cable is 6mm per square inch of copper.
- Automotive Cable size is 10mm per circumference
So we careful not to purchase undersized cable else you will suffer voltage drop. Most brake controllers have proportional control. As a result, NO voltage is applied to the brakes.
Your caravan must be in motion for your electric brake controller to work.
Apply a voltage to your brakes by pulling the pin on your breakaway kit.
You are also testing the contacts within the housing in this exercise. Pull the pin on your breakaway kit, and your electric brakes activate. It will be impossible to spin your wheel when it is off the ground if your brakes are ON and adjusted correctly. It should also be impossible to move your caravan forward without your wheels skidding.
This product has an extensive range of parts and accessories available. If your brakes are pretty old, consider replacing the entire backing plates. Backing plates are straightforward to uninstall.

Further, the shoes on electric brakes are not self-centering.
- With the parking brake facing at noon ensure the shoes are parallel with two outcrops on the backing plate located at 3 and 9 o’clock.
- Tap the shoes into position until they are perfect.
Finally, use 4 x 7/16″ UNF nuts to bolt the backing plate to the weld ring.
