12-inch Electric Backing Plate Brake Kit optional Highway or Off-Road Magnets

12-inch Electric Backing Plate Drum Brake Assembly suits Al-ko, Dexter, and VC 2t and 3t brake hub drums.

These robust backing plates are one of the best, most reliable brakes available. Additionally, they are made for Australian conditions.

Complete replacement of backing plates is often a better option than replacing worn components.

You may be unaware of other parts in your backing plate near the end of life. Replacing an entire backing plate is a relatively easy procedure.


  • Select from Highway or Off-Road magnets
  • The left-hand side is the passenger's side
  • The right-hand side is the driver's side
  • Premium off-road electric drum brake kit has a 2,500kg rating per pair
  • We recommend installing the hand brake mechanism on the TOP side of the backing plate. (noon)

Install Use 6mm to 10mm trailer cable for electric trailer brakes. Note: A larger cable significantly reduces voltage loss and improves braking performance.

  • 6mm Electric cable measures the cross-sectional area.
  • 10mm Automotive cable measures the circumference.

Do not wire electric brakes across the axle. Install wiring down each chassis rail separately to resolve voltage losses.

Installing a small cable to power electric brakes causes voltage loss

The wiring of electric brakes made easy provides great information on tips and tricks.

Parking brake lever

  • Al-ko model is horizontal.
  • Dexter's model is vertical.

Connect the hand brake cable to the front axle park brake lever only. If this cable is connected to the front and rear park brake handles, the torque from the coupling hand brake is halved.

Why can't I run the electric cable across my axle?

  • Rundown each chassis rail = 6mtr @ 6.4 Amps per pair of magnets = 5.62mm cable size
  • Run down the chassis trailer (inside) = 6 metre + 2 metre (8mtr) @ 6.4 Amps per pair of magnets = 7.5mm cable size

To resolve voltage drop, run electric cabling down each chassis rail.

A broad range of parts and accessories is available for this product.

TIP: Sometimes, it is easier to buy new 12-inch backing plates than to replace worn 12-inch brake shoes and brake magnets. Parts like magnet arms will also need replacing, as will springs that hold the brake shoes.
