Utility trailer axles equipped with electric brakes offer a convenient solution for
transporting equipment and small tractors, coming in various sizes to meet any load
specifications.
When working under a trailer, always support it using adequate capacity jack stands
to protect its suspension, brakes and wiring.
Brake Drums
These drum brakes use electromagnets to apply their braking force, providing more
consistent braking force with cheaper components and cost savings.
Electric brake controllers typically feature a modulation feature that reduces current
flow to trailer brakes when you press on your towing vehicle’s brake pedal and
gradually increases voltage as pressure is increased, thus relieving pressure from
towing vehicles and avoiding brake lag.
Trailer Parts Superstore provides a selection of one-piece cast trailer brake drum &
hub assemblies in various sizes and lug patterns from Dexter and other leading
manufacturers, some equipped with E-Z Lube technology for periodic lubrication
without the need to disassemble them from axle.
Brake Shoes
Utility trailer axles equipped with electric brakes require brake shoes that convert
energy into heat through friction, enabling the brake drum to stop the trailer wheels.
Brake shoes should be periodically replaced for optimal performance.
Most states mandate that any trailer over a certain size be equipped with brakes for
safety and control reasons, as well as to provide passengers, other road users and
cargo with a smoother ride experience. Brakes also help create an enjoyable journey
experience for everyone involved – passengers, other road users and cargo alike!
Dependent upon your trailer needs, surge or hydraulic disc, hydraulic drum, or
electric over hydraulic brakes may be appropriate for stopping. Electric brakes have
a longer break-in period and typically require an in cab controller while surge brakes
tend to require applying the brakes earlier for maximum stopping distances.
Brake Pads
Axle brakes help trailer owners stop and slow trailers quickly, enabling them to more
safely haul their load. Ensuring your brake drums, shoes, and magnet arm remain in
top shape ensures top performance from these integral systems.
Electric over hydraulic disc brakes work similarly to drum brakes in that they’re
operated via an in-cab controller, yet feature disc (rotor)/caliper components for
greater stopping force and reduced maintenance requirements over time.
Electric trailer brake systems are an ideal solution for boat, equipment, cargo and
custom trailers featuring receiver, fifth wheel or gooseneck styles. Their installation
process is also straightforward: simply hooking into your tow vehicle using a
standard wiring end plug and installing the electrical brake controller under your dashboard.
Brake Cables
Brake cables serve to transfer electrical and hydraulic pressure between your
trailer’s brake actuator and its associated car brakes, and require regular lubrication
for optimal functioning.
Electric over hydraulic brakes use your car’s brake controller to generate an
electronic signal proportional to your inertia change as you slow down, which then
signals your trailer’s hydraulic brake actuators to produce enough pressure to press
against its brake pads and stop. This method is far more efficient than surge brakes.
To install your new trailer axle, first lift its center point with your floor jack until it
clears the jack stands and then support it with them. Locate all power and ground
wires from your old axle and cut them before starting with your installation process.
Brake Controller
In-cab controllers play a crucial role in any braking system. By sending electrical
pulses directly to the trailer’s electric brakes, these pulses activate them for optimal
braking performance. Only more complex hydraulic or “surge” brakes may work without one.
Brake controllers come in two main varieties: proportional and time-delayed.
Proportional controllers use sensors to measure how often and hard your vehicle
brakes, and then they automatically adjust your trailer brake intensity accordingly –
helping prevent long-term wear on both sets of brakes.
Before driving, brakes should be burnished-in by accelerating and braking in an
open area, to ensure optimal synchronization between them and your vehicle. Also
be sure to read your manufacturer’s instructions regarding calibration settings as
these may differ depending on which model is being used.
