How Do You Brake When Towing?

Types of Braking Systems for Towing

Electric Trailer Brakes

Electric trailer brakes are a common braking system used for towing. This type of braking system utilizes an electric current to activate the brakes on the trailer. It works in conjunction with the brake controller in the towing vehicle. When the driver applies the brakes in the towing vehicle, the brake controller sends an electric signal to the trailer brakes, causing them to engage and assist in stopping the trailer. Electric trailer brakes are known for their responsiveness and ability to provide even braking pressure.

Surge Brakes

Surge brakes are another type of braking system commonly found in trailers. Unlike electric trailer brakes, surge brakes are not operated by an electric signal from the towing vehicle. Instead, surge brakes rely on the trailer’s momentum to activate the braking system. When the driver applies the brakes in the towing vehicle, the forward motion of the trailer compresses a hydraulic surge actuator, which then applies the brakes on the trailer. Surge brakes are popular for their simplicity and reliability, especially in situations where electric systems may not be feasible.

Hydraulic Over Hydraulic Brakes

Hydraulic over hydraulic brakes use hydraulic pressure to activate the brakes on the trailer. This braking system is often utilized in heavy-duty towing applications, such as hauling large boats or heavy equipment. In this system, there is a hydraulic brake actuator that receives pressure from the towing vehicle’s hydraulic system. This pressure is then transferred to the braking system on the trailer, providing efficient and powerful braking. Hydraulic over hydraulic brakes are praised for their high braking capacity and ability to handle heavy loads.

Electric Over Hydraulic Brakes

Electric over hydraulic brakes combine the benefits of both electric and hydraulic braking systems. This type of braking system utilizes an electric current to activate a hydraulic brake actuator, which then applies the brakes on the trailer. It offers the advantages of electric trailer brakes, such as the ability to modulate braking pressure and provide proportional braking, while also benefiting from the power and reliability of hydraulic brakes. Electric over hydraulic brakes are commonly used in towing applications where precise and powerful braking is required, such as towing large RVs or horse trailers.

Factors to Consider for Braking when Towing

Weight of the Trailer

One of the most crucial factors to consider when braking while towing is the weight of the trailer. The weight of the trailer directly impacts the braking distance, braking power needed, and the potential for brake overheating. It is important to ensure that the towing vehicle’s braking system is capable of handling the specific weight of the trailer to ensure safe and effective braking.

Weight Distribution

In addition to the overall weight of the trailer, the weight distribution of the load on the trailer also plays a significant role in braking performance. Proper weight distribution helps ensure that the braking forces are evenly distributed across all wheels, providing stable and controlled braking. Improper weight distribution, such as having too much weight concentrated on the front or rear of the trailer, can lead to imbalanced braking and potential stability issues.

Road Conditions

The road conditions also have a significant impact on braking when towing. Factors such as wet or icy roads, steep downhill grades, or uneven road surfaces can affect the traction between the tires and the road, potentially reducing braking effectiveness. It is important to adjust braking techniques accordingly and exercise caution when encountering adverse road conditions while towing.

Braking Distance

The braking distance, or the distance it takes for the towing vehicle and trailer to come to a complete stop, is another crucial factor to consider. The overall weight, weight distribution, road conditions, and braking system all contribute to the braking distance. It is essential to leave enough stopping distance between the towing vehicle and the vehicle in front to allow for safe and controlled braking.

Braking Techniques when Towing

Gradual Braking

One of the key techniques when braking while towing is to apply the brakes gradually. Gradual braking helps prevent excessive strain on the braking system and promotes stability by allowing the weight transfer between the towing vehicle and the trailer to occur smoothly. By gradually applying the brakes, you can control the braking forces and reduce the risk of the trailer swaying or jackknifing.

Pumping the Brakes

Pumping the brakes is another technique commonly used when towing. It involves rapidly applying and releasing the brakes in quick succession. This technique helps prevent the brakes from overheating and losing effectiveness, especially during long downhill descents. By constantly pumping the brakes, you can alternate between applying pressure and allowing the brakes to cool down, aiding in maintaining optimal braking performance.


Downshifting can be an effective technique for assisting in braking when towing. By downshifting to a lower gear, you can take advantage of the engine’s braking power to help slow down the towing vehicle and trailer. This technique reduces the reliance on the brakes, alleviating some of the strain on the braking system and potentially extending brake life. However, it is important to exercise caution and not downshift abruptly, as this can cause the trailer to jerk or put excessive strain on the transmission.

Trailer Brake Controller

Utilizing a trailer brake controller is an essential component for effective braking while towing. A brake controller allows the driver to control the level of braking force applied to the trailer brakes. It ensures proportional braking, where the trailer brakes engage proportionally to the towing vehicle’s brakes, promoting stable and controlled braking. With a brake controller, you can adjust the sensitivity and braking aggressiveness to suit the specific towing conditions and trailer weight.
