There are two kinds of brakes:
1 - Over-ride braking systems.
The over-ride braking systems are activated when the vehicle starts to slow down and the compression of the coupling by the inertia activates the trailer braking system. The over-ride braking system is generally used when the Gross Trailer Mass (GTM) is up to 2,000kg. If you are required to tow over 2,000kg, you will require braking on all wheels of the towed trailer as well as an automatic breakaway system to be applied.
2 - Electric brake system – these are needed when towing over 2,000kg.
If you are required to tow over 2,000kg you will need to ensure you have an electric braking system fitted. The electric braking system automatically applies the brakes on the trailer at the same time the vehicle brakes are applied. You will also have the ability to adjust and tune the braking force of the trailer using the electric brake controller, this will provide a much smoother and balanced brake.
