The 12" Electric Backing Plate is supplied as a whole assembly and includes the magnet and brake shoes.

  • Pre-drilled with five holes.
  • Hole Centres: 55mm x 78mm
  • Rating: 2500kg (per pair)

TIP: Left side refers to the passenger's side, whereas the right side is the driver's side.

Upgrading from 10-inch Brakes

Many customers call Couplemate™ to get help upgrading their 10-inch brakes to 12-inch brakes at home. More often than not, this requires upgrading the entire axle.

Going from drum brakes to calliper brakes on the same bearings (or same axle) is a much simpler process.

Not sure? Contact our expert team.

Standard backing plates are known as "AL-KO" backing plates and are the most common style in Australia.

However, some manufacturers will use Dexter brake systems, or " American-style" backing plates.

One way to identify this is through the park brake lever:

  • Horizontal Park Brake: Standard
  • Vertical Park Brake: Dexter USA

For information on choosing magnet-types, read our short article on the difference between Standard and Off-Road brakes.

Couplemate™ backing plates are among the best, most reliable systems. Couplemate™ offers a 12-Month Manufacturer’s Warranty wherein materials and workmanship are guaranteed to be free of defects for the service life of the product (when used as recommended).
