Brakes & Brake Parts — Frequently Asked Questions
Does my trailer need brakes in New Zealand?
It comes down to the trailer's gross laden weight (the trailer plus its load), and it is the service brake — the main brake that slows the trailer as you drive — that the rules refer to. As a guide: up to 2,000kg a service brake is not required; from 2,001kg to 2,500kg a service brake is required; and from 2,501kg to 3,500kg both a service brake and a parking brake are required. Always confirm against the current NZTA guide to safe loading and towing for your specific trailer, or talk to us.
What is the difference between a service brake, a parking brake and a breakaway brake?
The service brake is the trailer's main brake, slowing it as you drive alongside the tow vehicle's brakes. The parking brake holds the trailer still once parked or unhitched, like a handbrake. The breakaway brake is an emergency system only, applying the trailer's brakes automatically from its own battery if the trailer ever separates from the tow vehicle.
How many safety chains does my trailer need?
Most trailers on New Zealand roads need one safety chain. Once gross laden weight goes over 2,000kg, two safety chains are required. A breakaway brake is required unless the trailer has an appropriate coupling together with those chains, which is why most ordinary trailers get by on a properly rated coupling and chains. Use rated shackles — general hardware-store shackles are not suitable.
What is the difference between override and electric brakes?
An override (or surge) system is self-contained: as you slow, the trailer pushes against the coupling and that movement applies the trailer brakes, either mechanically or hydraulically. No wiring to the tow vehicle is needed. An electric system uses a controller to apply the trailer brakes in proportion to the tow vehicle's braking, giving finer control and the ability to adjust braking effort, which is particularly useful on heavier trailers and caravans.
Do I need a brake controller fitted inside my vehicle?
Not necessarily. Traditional electric brake controllers are dash-mounted and hard-wired, but wireless Bluetooth units such as Elecbrakes mount on the trailer itself and are operated from a phone or a remote, which means no permanent installation in the tow vehicle and easy transfer between vehicles.
How do I know when trailer brake pads need replacing?
Reduced braking performance, a longer stopping distance when towing, squealing or grinding, or visibly thin friction material. On boat trailers, corrosion is often the bigger issue than wear, so check for seized calipers and scored or rusted rotors as well as pad thickness.
