Trailer Disc Brake Rotor – ElectroGal

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.

ElectroGal disc rotors are manufactured in Australia by Couplemate and feature cross-drilled, slotted discs.

The foundation upon which building and designing this superior disc rotor, was selecting the high-grade steel needed to withstand the drilling process.

This disc rotor sets the industry standard for disc-braking axles and is the most popular rotor within our axle builds.

What is ElectroGal?

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

The process begins with the disc rotors undergoing a chemical cleaning of oils, dirt, dust and grime before being electrically bonded to a preparation coating prior to the ElectroGal process.

Cross-Drilled for Superior Performance

Electrogal disc rotors release gases and particles from the brake pads during braking. As a result, particles will form a layer that prevents the pad from touching the disc as effectively. Brake fade is the result of this phenomenon.

Superior braking is achievable by drilling holes through the disc, this will give the gas and particles somewhere to escape.

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.

Due to the cross-drilling on the disc face, these are available separately to suit the left-hand side and right-hand side. A smooth surface, free of disc and gases improves braking efficiency and provides effective braking.

Not only is our new disc more efficient, but they also look pretty awesome.
