BrakeS
The electric brakes on the recreational vehicle are similar to the drum brakes on the automobile. The
difference is that automotive brakes are actuated by hydraulic pressure while electric recreational vehicle brakes
are actuated by an electromagnet. With all of the brake components connected to the system, the brake will
operate as follows:
When electrical current is fed into the system by the controller it flows through the electromagnets in the
brakes. The high capacity electromagnets are energized and attracted to the rotating armature surface of the drums
which moves the actuating levers in the direction that the drums are turning.
The resulting force causes the actuating cam block at the shoe end of the lever to push the primary shoe out
against the inside surface of the brake drum. The force generated by the primary shoe acting through the adjuster
link then moves the secondary shoe out into contact with the brake drum.
Increasing the current flow to the electromagnets causes the magnet to grip the armature surface of the brake
drum more firmly, resulting in increased pressure against the shoes and brake drums until the desired stop is
accomplished.
Brakes Synchronization
Recreational vehicle brakes are designed to work
in synchronization with tow vehicle brakes. Never use
tow vehicle or recreational vehicle brakes alone to stop
the combined load. The recreational vehicle and tow
vehicle will seldom have correct amperage flow to the
brake magnets to give comfortable, safe braking unless
proper brake system adjustments are made. Changing
the recreational vehicle load and driving conditions, as
well as uneven alternator and battery output, can mean
unstable current flow to brake magnets. It is imperative
to maintain and adjust brakes as set forth in this
manual, use properly modulated brake controller and
perform the synchronization procedure noted below.
In addition to the synchronization adjustments
detailed below, electric brake controllers provide a
modulation function that varies the current to the
electric brakes with the pressure on the brake pedal
