In a trailer surge brake system the pump is located on the trailer-as part of the hitch assembly. All the Surge Brake Actuators below are designed for Straight 3 inch wide trailer tongues.
In the next few minutes youll learn how surge brakes work why they are the most popular form of trailer.
Surge brakes for boat trailer. Also known as Hydraulic Surge Brakes surge brakes are extremely common in boat trailers and rental or leisure trailers. Surge brakes are not exactly driver-controlled. They activate automatically whenever the driver slows the tow vehicle.
In the next few minutes youll learn how surge brakes work why they are the most popular form of trailer. Youll find surge brakes in most boat trailers today. Surge brakes are not dependent on a driver.
Instead they activate automatically. As a result there are also some cases where surge brakes activate when they are not supposed to. However to better understand this you need first to understand what exactly surge brakes are and how they and their emergency breakaway.
All the Surge Brake Actuators below are designed for Straight 3 inch wide trailer tongues. They are Bolt on assemblies. Surge Brake actuators are manufactured specifically for either Hydraulic Disc or Hydraulic Drum Brakes.
The difference between the two designs lies in the Master Cylinder. Marine-grade hydraulic drum brake assemblies are great for boat trailers Designed for use with surge -type trailer brake actuators Free-backing design lets you back up without engaging. Hydraulic Drum Brakes 3500 lbs Axle 10 x 2-14 Inch Drum 14 Inch Wheel 14-12 Inch Wheel 15 Inch Wheel Free Backing Brake Set etrailer.
There is a spring and a little shock absorber in the surge unit in the tongue that pushes back against your hitch to release the brakes and damp the braking action. Over time the spring weakens and the shock absorber can weaken or fail. You might want to take a look at that to see if it jammed or broke.
Yes there is a way to back up your boat trailer and keep the surge brake actuator T43329007K from applying pressure to the trailer brakes. The cover will keep the solenoid from getting stepped on and damaged when installed inline between the master cylinder and the existing brake line.

Includes internal piston seals and spring. Their are many options for Boaters needing Hydraulic Disc Brakes whether your using these on your 5 Lug 6 Lug or 8 Lug Trailer Wheels. There are several Variations of both Brake Kits some with Hubs some Slip On Style and some Integral style.
Both Have Coated Materials and Stainless Steel Components for Maximum Corrosion resistance. How Hydraulic Surge Brakes Work In contrast Surge Brakes are hydraulic and use the trailers natural momentum to actuate the brakes. When you step on the brake in your tow vehicle and slow down the trailer pushes against the hitch and presses a hydraulic cylinder.
The more you slow down the vehicle the more pressure on the trailer brakes. So maybe thats the difference. Surge brakes are still good for applications up to and including say 7000- or 8000-pound boat trailers.
Anything from there up could benefit from the smoothness and adjustability of electric-over-hydraulic. I think we might begin to see more of electric-over-hydraulic systems used on boat trailers probably. How do surge brakes work on boat trailer.
Surge brakes work by mounting a brake master cylinder in the trailer coupler and normal hydraulic brakes on the wheels. As the vehicle brakes the trailer is pushed into the vehicle which causes the ball to depress the master cylinder activating the trailer brakes. Many boat trailers have brake systems.
Boat brake systems are either electric brakes actuated by a switch in the tow vehicle brake pedal or hydraulic surge brakes. Surge brakes work when a hydraulic pushrod senses deceleration from the tow vehicle and sends hydraulic fluid that applies the brakes. These brakes are fairly simple and can be repaired by the boat owner using tools.
Trailers with Surge Brakes A trailer with surge brakes cannot be backed up without inserting a pin in the neck of the trailer. When the tow vehicle is in reverse pushes in on the trailer neck which would activate the surge brakes. Inserting a pin in the neck of the trailer prevents this from happening while the driver is backing up.
Hydraulic surge brakes- this is the most common form of boat trailer brakes. The technology behind this kind of brakes is straightforward and works excellent. Basically they use the trailers momentum to apply hydraulic pressure to the brakes and slow down the trailer.
There are two types of brakes for boat trailers electrichydraulic and surge. It all depends on the needs and preferences of each person. Electrichydraulic brakes have a pump on the trailer that as soon as you press the brakes on the tow vehicle the pump sends the signal to release brake fluid to the calipers.
In a trailer surge brake system the pump is located on the trailer-as part of the hitch assembly. This special sliding hitch assembly is called a surge brake actuator. It has a master cylinder built into it but instead of using your foot to operate it it uses the weight the momentum of the trailer to do the pumping.
Surge brake systems are relatively simple and effective. Thats the good news. The design choices are few.
Drum type or caliper type. Drum type systems are slightly lower cost and strong enough for most trailerable sailboats so thats what I chose. But the tongue extension of our trailer posed a couple of uncommon build challenges.
I just installed a complete Tie Down engineering disc surge brake kit on my trailer to replace rusted non functional original. I use the trailer twice a year in fresh water only. I noticed the brakes were dragging a touch after I.
How Hydraulic Surge Brakes Work. In contrast Surge Brakes are hydraulic and use the trailers natural momentum to actuate the brakes. When you step on the brake in your tow vehicle and slow down the trailer pushes against the hitch and presses a hydraulic cylinder.
The more you slow down the vehicle the more pressure on the trailer brakes.
