Breakaway Kit Incl 5ah Battery, Switch and 12v/5A Battery

The Breakaway Trailer Brake Kit is mandatory for all trailers over 2000 kg GTM. Should the tow vehicle and trailer separate accidentally, the breakaway kit engages the electric brakes at full power for a minimum of 15 minutes.

Safety is key when it comes to driving. One important aspect of ensuring a safe driving experience is having well-functioning brakes.

However, standard brakes may not be enough for those who enjoy racing or pushing the limits of their vehicle’s performance. This is where breakaway and brake kits come into play.

A breakaway system is essentially an emergency braking system separate from the primary one. It is designed to activate in the event of a catastrophic brake failure. Some breakaway systems use a cable that is attached to the brake pedal or lever, while others use a hydraulic system.

The main advantage of a breakaway system is that it provides an additional layer of safety in case of brake failure, which can be especially important for high-speed racing or other extreme driving situations.

Overall, breakaway and brake kits are significant upgrades for those who demand more from their vehicle’s braking system. Whether you’re a racer or simply looking for an extra layer of safety, these upgrades can help ensure your car is equipped to handle any situation on the road or track.

Breakaway Replacement Parts

Caravan and Trailer onboard Battery Kit

It is essential to note that an independent, designated, or separate breakaway battery system is not required.

In other words, the caravan or camper onboard 12v battery is the breakaway battery provided it can apply 12vdc to your electric brakes.

Further, the onboard caravan battery will be larger than the minimum requirement and have the same or larger capacity than the smaller unit.

The breakaway switch activates the trailer brake system for 15 minutes in cases where the trailer was detached from the vehicle when travelling.

Additionally, included in the price is a rubber boot that fits over the breakaway switch. The rubber boot reduces or helps prevent water ingress.

Breakaway kit testing.

  • Connect the wires to the terminals. In a fully charged state, a green light will glow.
  • Remove the pin and notice a sound coming from your magnets
  • You may hear a hum or a tick as the electric magnet sticks to the inside of the drum
  • When energised, check the Voltage at the battery
  • If the Voltage is under 12 volts, the battery is putting out less than 12v, or you have a voltage loss.
  • If voltage loss exists, increase the cable size to the brakes to 4mm or 5mm.

Increasing the size of the cable removes voltage loss and restores Voltage to 12vdc.

Breakaway Trailer Brake Kit for Hydrastar

Electric / Hydraulic controllers use a 17 Amp Hour battery because the hydraulic motor uses more power than an electric magnet.

Standard 1200 psi and 1600psi Hydrastar actuators use a 5ah Breakaway Kit battery,

An excellent read about the Caravan and Trailer Breakaway Kit article.

How do I tell when the battery requires replacement?

Your breakaway battery will require replacement when you cannot get a green light on your control panel.

In Australia, the test button must indicate

  • Full Battery Power is Available.
  • Battery Charging.
  • Battery flat

This is in contrast to America, where there is no requirement for test lights.

If your battery does not charge, then it needs replacing.

Finally, all trailers over 2000kg require a breakaway system.
