We've been involved in install and wiring vehicle for towing vehicle for just about the same time as we've
been working in caravans. We know what gauge cables to and should be used to make the braking system
work as affectively as possible and how a brake system should be intersected int a vehicles operating
wiring without causing any concern with warranty or cam-bus interference.
You should always use a professional like Absolute Caravan Care when putting your foot down and
stopping correctly.

The brakes on your Caravan will not work unless you have a 12volt brake control module installed into your
vehicle. This device is known as an Electric Brake Controller, by law it has to located within in easy reach of
the driver, the brake controller is connected to the car’s battery, it is activated by the stop light circuit
of the towing vehicle and is connects to the caravan through the seven or twelve point trailer socket.

Australian Design rules state that trailers over 750 kg GTM must have an effective brake system fitted
(irrespective of the vehicles towing capacity or unladen mass).

An electric brake in the tow vehicle will enable the electric trailer brakes to function.  Its placement should be
readily accessible by the driver, most brake controllers are mounted under the dashboard.  A correctly set
up electric brakes will stop the effect of the (weight of the) van pushing the tow vehicle along.

Caravans and trailers over 2000 kg usually have tandem axles and must have brakes operating on all wheels
whereas caravans and trailers under 2000 kg must have efficient brakes operating to at least two wheels of
one axle
The electric connection between the tow vehicle and the caravan is done with a seven or twelve pin round or flat plug
(compulsory in Australia) and socket.  This connection operates the lights, stoplights, indicator lights, supplies the power for the
brakes, also the 12volt power supply for the fridge or general 12volt on the caravan or camper trailer.

The most efficient type of brake controller has a motion sensing device.  Some have features such as a self adjusting sensing
device to compensate for various terrain, self-levelling device and digital displays plus the ability to report electrical fault
conditions such as power loss and short circuits.  
Once the brake controller is set up and adjusted correctly the driver will be able to slow the vehicle and caravan or trailer
combination with smooth proportional braking.

DIGITAL OR PENDULUM inertia-activated brake controller applies power to the trailer brakes in proportion to the tow vehicle’s
deceleration.  The Tekonsha Prodigy has a self adjusting sensing device, a digital display showing voltage level delivered to the
trailer brakes plus a ‘boost’ feature that gives the user the ability to apply more initial braking power when towing heavier
trailers.  The Prodigy can brake up to four trailer axles but it is not designed for use with electric-hydraulic trailer brake systems

TIMER OR SYNC CONTROL brake controllers are a compact, slim-line controller and can be easily installed with a conventional
4 wire hook up. The Hayman Reese electric brake controller features a ‘Sync –Control’ of the output for the timing of the brakes
as well as the power.  A manual control is also located on the front of the unit.

Most brake controller manufacturers have installation instructions with the packaging of the device although most of this
information is available on their websites.

For caravans and trailers over 2000 kg GTM (2 ton) a breakaway cable/device is mandatory. This is required in the awful event
that the RV parts company with the tow vehicle.  When the cable is detached the trailer brakes are operated automatically.  
These heavy type caravans or trailers will also have two safety chains which must meet Australian Standards.

For caravan and trailers in excess of 2,000 kg GTM there will be Break Safe brake control unit in the front boot of the caravan
with its own 12V battery.  The Break Safe breakaway kit is designed to activate the caravan or trailer electric brakes as well as
the brake lights if the caravan or trailer becomes separated from the tow vehicle. This battery should be checked from time to
time by pressing on a ‘test’ button on the front of the unit, just remember that most of these breakaway devices only receive their
charge when the caravan is connected to the tow vehicle's 12volt power supply.

The trailer plug wiring to the tow vehicle should be disconnected before you do the test. A green light should glow if all is well, a
red light if battery is low or no light if battery is flat, although this unit will be connected to your vehicle for around 30minutes to
be charged enough to make the green light work.

PLEASE NOTE: These units use a 12volt 7A/hr lead acid battery, if this battery is left uncharged for any extended period of time
it will become open cell, meaning it will not hold a charge at all.
We recommend that battery be load tested every 12-18month and replaced if necessary, its no good having a Break Away
System when the battery to run it is not able to hold a charge long enough to operate the system in an emergency.
