Did you know that most states require trailer brakes for cargo above 3000lbs? So if you’re towing a boat or other heavy duty cargo, you’ll need to have brakes on your trailer in order to ensure a safe and legal towing experience. Trailer surge brakes and electric brakes are both viable options for ensuring that your trailer is safely and effectively stopped, but which one is right for you? Let’s take a look at the pros and cons of each option to help you make a decision.

What’s the Mechanical Difference?

Surge Brakes rely on hydraulics while electric brakes energize a brake controller when you depress the brake pedal. Though they work in very different ways, the end result is the same; they activate the brake shoe, which in turn causes friction between the brake lining and metal rotor, slowing the vehicle.

Much like the debate over round bars and trunnion bars, there is a wealth of online discussion clouding the issue of their differences. The biggest difference is that surge brakes are applied depending on how hard the trailer pushes against the towing vehicle. The hydraulics in place stop them from making contact by slowing the trailer.

Surge Brakes

Pros:

– Easier to install; do not require extra wiring or equipment

– Work automatically

– Often cheaper upfront cost due to simplicity

Cons:

– In very cold weather, the fluid in the surge brakes can freeze, rendering them ineffective

– Can be more expensive than electric brakes over time

– Automatic braking causes heavy brake strain on slopes.

Trailer Electric Brakes

While surge brakes operate with simple physics and do not require electricity, electric brakes are far more nuanced. Although electric brakes do require power, they are also more interactive. Electric brakes can be adjusted for the load being carried and manually applied if necessary. They also work better on slopes and rough terrain.

Pros:

– More consistent braking than surge brakes, which are effected by terrain and towing speed

– Can be manually activated for total control

– Less effected by weather conditions

Cons:

– Requires extra equipment like a controller and wiring, causing higher upfront cost and install time

– Modern innovations like computer to detect malfunctions also drives up cost in some models

– Relies on the battery of the tow vehicle

Which Brakes Are Right For You?

Surge brakes and electric brakes both have their own distinct advantages and disadvantages. Ultimately, the best option for you will depend on your specific needs and preferences. If you want an easier installation process and an automatic hydraulic system, choose surge brakes. However, if you need more consistent braking performance and the price is right, electric brakes may be the better option.

Regardless of which you prefer; you must have trailer brakes when towing more than 3000 lbs, so be sure that any current or future purchases have trailer brakes in mind.
