How Do Surge Brakes Work | Functioning of Surge Brakes: Explanation 2023
Last Updated on August 16, 2023 by Jisan
Surge brakes are designed to slow down and stop a trailer. They work by using hydraulic pressure to push the brake pads against the rotating drum on the wheel. This creates friction, which slows down the wheel.
Surge brakes are a type of braking system that uses hydraulic pressure to activate the brakes. When the trailer is connected to the tow vehicle, the surge brake system is automatically engaged. As the tow vehicle slows down, the pressure in the surge brake system increases, which activates the brakes on the trailer.
This type of braking system is often used on boats and trailers because it provides more stopping power than traditional brakes.
Backing Up With Surge Brakes
Backing up with surge brakes is a great way to ensure that your vehicle stays in place while you are backing up. These types of brakes are typically found on trailers and RVs. When you put your vehicle in reverse, the surge brake will engage and provide extra stopping power to keep your vehicle from rolling backward.
Here are some tips for backing up with surge brakes:
– Make sure that you have plenty of room to back up. You don’t want to be too close to any objects or other vehicles.
– Slowly apply pressure to the brake pedal. The goal is to not lock up the wheels and cause the trailer or RV to skid.
– Use caution when backing up on hills or inclines.
The surge brake can cause the trailer or RV to roll backward if not used correctly.
How to Test Surge Brakes
If you are towing a trailer with surge brakes, it is important to know how to properly test them before hitting the road. Surge brakes are designed to engage when the tow vehicle slows down or comes to a stop, so it is vital that they are functioning correctly. Here is a step-by-step guide on how to test your surge brakes:
1. Hook up your trailer to your tow vehicle and make sure that everything is secure.
2. With the engine off, engage the trailer’s electric brake controller (if it has one) and manually apply the trailer brakes by pushing down on the lever or pedal. You should feel resistance as the brakes engage.
3. Start your vehicle’s engine and slowly drive forward while paying attention to the trailer’s brake lights. As you accelerate, the brake lights should come on and then go off as you reach cruising speed. If they stay on, this indicates that the surge brakes are not working properly.
4. To test emergency braking, quickly come to a stop while continuing to pay attention to the trailer’s brake lights. The brakes should engage forcefully and cause the brake lights to stay on until you release them again. If they do not engage or if they do not cause the brake lights to come on, this indicates that there is an issue with the surge brakes which needs to be addressed before hitting the road.
Surge Brake Actuator
A surge brake actuator is a device that is used to apply the brakes in a trailer. It is designed to provide braking force when the trailer is being towed behind a vehicle. The actuator is mounted on the tongue of the trailer and is connected to the tow vehicle’s brake system.
When the tow vehicle slows down, the actuator applies pressure to the trailer’s brakes, causing them to engage.
Trailer Surge Brake Kit
A trailer surge brake kit is a great addition to any trailer. This type of brake uses pressure from the tow vehicle to engage the brakes on the trailer. This can be a great safety feature, as it allows the driver of the tow vehicle to have more control over stopping.
The kit includes all of the necessary hardware and instructions for installation.
Boat Trailer Brakes Electric Or Hydraulic
If you’re shopping for a new boat trailer, you might be wondering whether to choose electric or hydraulic brakes. Here’s a look at the pros and cons of each option to help you make the best decision for your needs.
Electric brakes are typically more affordable than hydraulic brakes, and they’re easy to install.
Electric brakes also offer good braking power and are low maintenance. However, electric brakes can drain your vehicle’s battery if they’re used frequently, and they may not work as well in cold weather.
Hydraulic brakes are more expensive than electric brakes, but they offer superior braking power.
They’re also less likely to be affected by cold weather than electric brakes. However, hydraulic brake systems can be complex to install and require more maintenance than electric brake systems.

Can You Backup a Trailer With Surge Brakes?
If you have a trailer with surge brakes, you can back it up without any problems. Just be sure to go slowly and use caution, as you would with any other vehicle.
Are Surge Brakes Any Good?
Surge brakes are a type of mechanical braking system that uses the force of inertia to engage the brakes. When the trailer is towed, it wants to continue moving forward due to inertia. The surge brake system uses this force to push a piston in the master cylinder and create hydraulic pressure.
This pressure is then used to engage the brakes on the trailer wheels.
There are several advantages to using surge brakes over other types of braking systems. First, they are much simpler and require less maintenance than electric or airbrake systems.
Second, they are more effective at slowing down a heavy load than manual brakes. Third, they provide better control when descending steep grades because they automatically adjust braking pressure based on speed and weight. Finally, surge brakes are less likely to cause wheel lockup than other types of brakes, which can result in a loss of control and an accident.
Despite these advantages, surge brakes have some disadvantages that should be considered before choosing them for your vehicle. First, they can be difficult to install correctly if you don’t have experience with mechanical brake systems. Second, they rely on hydraulics which can fail if not properly maintained.
Third, they can be less effective in cold weather since the fluid can freeze and prevent proper operation. Finally, surge brakes add weight to your vehicle which can impact fuel efficiency slightly negatively..
How Do I Know If My Surge Brakes are Working?
Your car’s surge brakes are designed to engage automatically when you reverse your car. There are a few ways to tell if your surge brakes are working properly.
One way is to look at the brake light on your dash.
If the light is illuminated, it means that the surge brakes are engaged and working.
Another way is to physically check the brake pads. If they are worn down, it indicates that the brakes have been used frequently and are likely in good working condition.
If you’re still unsure, you can always consult a mechanic or dealership for assistance.
Do You Need a Brake Controller for Surge Brakes?
If you have surge brakes on your trailer, you do not need a brake controller. The brakes are activated by the weight of the trailer pushing down on a piston in the coupler. This pressure is transferred to the brakes themselves, which then activate and apply pressure to the wheels to slow or stop the trailer.

Conclusion
Surge brakes are a type of trailer brake that uses the inertia of the trailer to engage the brakes. The surge brake is activated by the pressure from the tow vehicle pushing against the back of the trailer when it slows down or stops. This pressure activates a hydraulic piston in the surge brake actuator, which then applies the brakes on the trailer wheels.
