Most states require brakes on trailers (at least trailers over 3,000 lbs gross weight) and brake controllers are also commonly required. Of course being in compliance with the law is important, but isn’t safe hauling your goal? We thought so. Read on.
Trailer Brakes 101
While they type of braking system you’ll need depends on your trailer/tow vehicle combination, there are only two main types of brakes: Electric and hydraulic.
Electric brakes are essentially like the brakes on a vehicle (featuring disc or drum brakes) activated by the tow vehicle driver, with an electrical system (wiring) runs between the trailer and tow vehicle controlling brake function.
Key to set-up is making sure stopping action and delay settings are established to
Hydraulic surge brakes are different: they automatically apply braking pressure to the trailer whenever the driver slows the tow vehicle. (Sensors are triggered through wiring in the hitch.)
One important part of set-up and installation is making sure the braking actuator is properly in sync with tow vehicle operation. Setup must take into account trailer weight (including typical loads) and usual driving speed, as during braking, the trailer presses against the hitch and compresses the braking actuator.
Brake Controller Basics
The two primary types of brake are proportional brake controllers and time delayed brake controllers. (We sell and service both.)
Proportional brake controllers use sensors to determine tow vehicle speed (and specifically, stopping speed) to ensure the trailer stops at the same rate as the tow vehicle. Not only is it safe, it reduces wear on both the tow vehicle and the trailer’s braking systems.
Brake controllers typically come with a four-wire configuration (trailer feed, ground, brake switch and battery power) and many trucks and other common tow vehicles come with built-in wiring systems for brake controllers. That’s not to say it’s a “plug and play” situation – we see many built-in systems that require some adjustment. Those are typically very easy (inexpensive) fixes, but if there is any concern about the way your brakes are working on your trailer, we recommend making an appointment right away.
