Trailer Disc Brake Rotor – ElectroGal

The ElectroGal trailer disc brake rotor is 10 inches in diameter and is used for braking boat trailers up to 1450kg.

Australian MadeElectrogal disk rotors are manufactured in Australia by Couplemate and feature cross-drilled, slotted discs.

HIgh-grade steel was chosen as the foundation upon which to build this superior disc rotor.

This disc rotor sets the industry standard for disc braked axles and is the most popular rotor used in our axle builds.


ElectroGal is an electrolytic coating formed on disc rotors due to the application of an electric current onto an anode and cathode.

The disc rotors are chemically clean of oils, dirt, dust and grime before being electrically bonded to a preparation coating before the ElectroGal process.

Cross-Drilled or Slotted

Electrogal disc rotors release gases and particles from the brake pads during braking. These particles form a layer that prevents the pad from touching the disc as effectively. This phenomenon is referred to as brake fade.

Superior braking is achieved by drilling holes through the disc give the gas and particles somewhere to escape.

Slots or grooves on the disc face also allow gases to escape, and there are additional benefits.

The ‘scraping’ action of the slots can clean the pad, and the edges of the groves increase friction, albeit at the expense of pad wear.

A smooth surface, free of disc and gases improves braking efficiency and provides effective braking.

And finally, like drilled discs, not only is the disc more efficient, but they also look pretty awesome.
