Braking Systems
Electric Brakes
The Simpson comes fitted with electric brakes which require a brake controller installed into the
towing vehicle that can be controlled from the driver’s seat. There are many systems available
which can either be permanently installed into the tow vehicle or Bluetooth units that are mounted
to the trailer and have a remote to control from the driver’s position. You must have a brake
controller installed in the vehicle or a Bluetooth unit on the day of handover otherwise the camper
will not be released to you.
Electric trailer brakes are designed to assist your vehicle brakes to stop in a safe and effective
manner. It is important that both your vehicle and the trailer are serviced regularly. The trailer
brakes will have a run-in period that will vary trailer to trailer, but it is important to have the trailer
brakes inspected and adjusted by a qualified professional in line with the maintenance schedule.
During your regular services, a qualified professional will complete a visual inspection of the brake
shoes to determine if they require replacement. Replacement will be necessary when the lining is
worn down to approx 1.5mm, or abnormally scored or gouged.
Scouring and gouging of the brake shoe lining is generally due to overheating of the brake system or
dirt caught in between the shoe and the hub. It is important to ensure that the brakes are adjusted
correctly and cleaned thoroughly after each trip, especially if there were water crossings involved.
Trailer Plug Wiring
The Simpson comes fitted standard with a 7-pin flat trailer plug.
If a different plug configuration has been requested, please reach out to your local showroom or
the service department to obtain a copy of the wiring diagram.
Anderson Plug
The Simpson is fitted with an Anderson connection at the drawbar. This is wired directly to the
batteries through a circuit breaker inside the water tank change over compartment. This is designed
to run all regulated sources of charging to the batteries and can also be utilised as a power output if
required.
To adequately charge from your vehicle, you will need to have a DC-DC charger installed into your
vehicle. Without this, you will receive some charge, but it will rarely be enough to charge the batteries
to capacity.
