the rate of deceleration.
When stationary, if the bakes are operated. Brake Commander will only provide a minimal
brake response as there is no deceleration.
The Sensitivity or “Gain” can be adjusted independently in both the forward and reversing
directions. The Sensitivity allows the brake response to be tuned to suit the weight of the
trailer and/or the drivers personnel preferance. Ideally the sensitivity should be set so as the
tow vehicle and trail feel to brake equally. To achieve this:
• While driving slowly in a safe area
• Set the forward sensitivity to an initial value, 40% is a good starting point.
• Brake lightly at a constant rate, check if the trailer brakes can be felt.
• Repeat the test until the trailer brakes are just felt to be braking harder than the tow
vehicles.
• Then reduce the forward Sensitivity by approximately 5%.
All settings are stored in the Brake Commander device, if a new or different remote is
connected, it will access the values stored in the device.
If the Wireless Remote is lost or damaged the braking system will continue to provide braking,
however the minimum brake response will be significantly higher so as to act as a warning to
the driver that a remote is not present. Operating in this condition is not recommended and
should be resolved as soon as possible.
If the driver forgets to turn the lights ON or there is an electrical fault preventing
the normal power supply, Brake Commander will be charged every time the driver
uses the brakes, once sufficiently charged, the braking system will provide braking,
however the minimum brake response will be significantly higher so as to act as a
warning to the driver of the condition. Operating in this condition is not recommended
and should be resolved immediately.
Brake Commander provides a Park Brake function that can be used in temporary
conditions only. The park brake function can applied by double clicking the “+”
(plus) button and released by double clicking the ”-” (minus) button. The function
can be applied or released whenever the device is sufficiently charged. Additionally
operating the Brakes will release the Park function automatically.
