Choosing the correct braking system for equipment trailers can be a little more complex than it first appears. Local regulations in the territories you serve might vary, especially if you cross state lines. All states have laws requiring brakes on trailers with gross vehicle weight ratings (GVWRs) greater than 3,000 lbs. This is the maximum weight of the trailer including the load.

But in some states, brakes may be required for GVWRs as low as 1,000 lbs. In addition, some states require brakes on all axles if the GVWR exceeds a specified weight. Be sure you check with the Department of Transportation in the areas where you plan to do your towing.

Brake size can also play an important role in owning and operating costs. In the 60,000- to 90,000-lb. capacity, a lot of the standard brakes are smaller in size. "We recommend large brakes (16 1/2 by 7 in.) for a few reasons: they run cooler, they last longer and you get better braking," says Marv Odegaard, Trail King.

But cost often becomes the deciding factor. "Unfortunately, people are sometimes only concerned about dollars," Odegaard says. "It's usually not an issue until they make the wrong decision. Then the next time they come back in, it's an issue."

Small equipment trailers

Equipment trailers towed behind a pickup tend to use either electric brakes or hydraulic surge brakes. Each has its advantages and drawbacks. Surge brakes are self contained on the trailer. The brakes work via the difference in inertia between the tow vehicle and the trailer. As the trailer pushes against the tow vehicle, a master cylinder at the junction of the hitch and trailer tongue actuates the trailer brakes.
