BRAkES
Brake Controller
The recreational vehicle brakes are
controlled electrically. This requires a brake
controller be mounted inside the tow vehicle.
The brake controller varies voltage output to
change braking force.
Increasing voltage (gain) increases the
amount of braking force. To ensure safe
brake performance and timely reaction of
the recreational vehicle brakes, the brake
controller will need to be synchronized so the
tow vehicle brakes and recreational vehicle
brakes react progressively in unison.
Brake controllers come in two basic
configurations; Proportional and Time
Delayed. While both systems have adjustable
gain control, the difference is how and when
the control signal to the brakes is generated.
Proportional controllers use an
adjustable pendulum that senses the
amount of braking inertia. Changing
pendulum angle changes inertia
sensing and when the control signal is
generated.
Time Delayed controllers use a timer.
The control signal is generated shortly
after the brake lights illuminate.
Both gain and synchronization (proportional
controller) adjustment will require practical
application testing. Thoroughly review the
brake controller manufacturer’s instructions to
properly adjust controller settings. Testing will
involve increasingly aggressive stops on dry
pavement, free of sand and gravel. Optimum
synchronization and gain settings are correct
when the driver does not get the sensation the
recreational vehicle is pushing the tow vehicle
or the recreational vehicle is over-braking.
Gain settings will change based on load. Refer
to the instructions in the OEM brake control
manual on how to synchronize the brake
control system.
NOTE:
Refer to brake controller OEM
manual for further information and
adjustment settings.
CAUTION:
Verify the area is clear of
vehicular and pedestrian traffic
before performing a brake
synchronization test.
NOTE:
Minimum stopping distance is
achieved when wheels approach
lock-up. Wheel lock-up results in
poor vehicle stability and control.
Not all recreational vehicle brakes
are capable of wheel lock-up.
This depends on the load, brake
type, tire to surface traction. Gain
settings will change based on load.
Electromagnets
The brake controller charges an
electromagnet. The magnet rides against a
machined surface of the brake drum. When
energized, it moves an actuating lever that
expands the brake shoes against the drum.
Increasing gain (voltage) to the electromagnets
causes the magnet to grip the machined surface
more firmly resulting in increased braking
force. It is normal for the electromagnets to
click when applying the brakes
The electromagnets and the machined
surfaces of the brake drum are inspected
during routine wheel bearing maintenance or
when brake performance degrades. This is an
indicator either the electromagnet is worn or
the brakes are out of adjustment or both. The
electromagnet is replaced as a component.
