Hayes G2 Brake Controller 81792BB
Introducing the new
Hayes G2 trailer brake controller with an audible signal alert for connection
continuity a market exclusive feature that makes for safer braking. The easy to
find, easy to use manual emergency braking control lets you apply full power in
emergency stopping situations. The three axis accelerometer technology
automatically levels and senses the rate of deceleration. The G2's large,
high-resolution diagnostic liquid crystal panel is recessed to eliminate glare.
The easy to read digital display indicates the amount of power being sent to
the trailer brakes and allows adjustment in three modes percent of power,
voltage, and current. This advanced controller has a power boost feature which
gives you the ability to apply more initial braking power when towing heavy
trailers. The G2 is compatible with the new Hayes universal quik-receiver
mounting sleeve to make installation a snap. For 2, 4, 6, and 8 electric
brakes, limited life.

Mounting Angle and
Mounting Direction
Mounting angles between
–35 and + 90 degrees can be accommodated by the controller. The unit must,
however, be installed so that it is parallel with the travel of the tow vehicle
and trailer. Use the included reversible slotted mounting bracket and machine
screws and fasteners to mount your controller with the back of the controller
toward the front of the vehicle. Always be sure to mount in a location which
allows the driver to easily apply the manual override and to see the red
indicator light.
Automatic Operation with
LCD Display
During braking, the G2
senses deceleration of the tow vehicle. An internal sensor measures the amount
of deceleration and sends a proportional amount of power to the trailer brakes.
The maximum braking supplied depends on the set up of the controller. The LCD
display will indicate the amount of power being sent to the trailer brakes.
Once the brake pedal is released, the unit will remain in the “MAIN SCREEN.”
While standing by and during braking, the controller will display the MAIN
SCREEN: % power, voltage bar graph, brake type (electric or hydraulic), and
selected Boost setting (B0-B4).
Built-In Audio Alerts
The G2 brake controller
has an audible alert for faults. This function can be turned off if not wanted.
The default is for the audible alert to be set to ON.
Boost Settings
The controller is
factory pre-set to a Boost Setting of B2 (10%). At this setting, the minimum
amount of power that will be immediately applied to the trailer brakes is 10%
(when the brake pedal is depressed and before deceleration is detected). The
selected Boost setting controls the minimum power in automatic and manual
operation (as a percentage of total available power). Changing the Boost
setting is designed to allow more or less power to be delivered to the brakes
when the controller does not sense deceleration. See the user manual included
with the controller for loaded trailer weight guidelines and select the Boost
setting required for your loaded trailer weight. The Boost setting may be
changed in 5% increments (B0 = off, B1 = 5%, B2 = 10%, B3 = 15%, and B4 = 20%).
Maximum Power with Automatic
and Manual Settings
Under automatic braking
(via brake pedal), the maximum power is the percent of available power that is
sent to the trailer brakes. Under manual override (via manual slide lever), the
maximum power is the percent available power that is sent to the trailer brakes
when the manual slide lever is moved all the way to the left. Choose Automatic
Maximum Power settings to use the factory pre-set of 50% Maximum Power, or
adjust the settings to your preferred amount of braking power. Use the Manual
Override slide lever to apply the trailer brakes independently of the tow
vehicle brakes or to override the automatic trailer brakes when less braking is
required. The Manual Override slide lever can be used for emergency stopping or
for control of excessive trailer sway. The tow vehicle and trailer brake
stoplights will still illuminate during the manual lever activation.
