When you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer toward the rear of your vehicle. With surge brake systems, the actuator is triggered as your trailer moves forward, once your tow vehicle starts to slow down. When this happens, the actuator contracts, applying force to its master cylinder. This in turn supplies the necessary hydraulic pressure to engage the trailer's brakes.


Electric Reverse Lockout

The electric reverse lockout on this trailer brake actuator is automatically activated when you shift your tow vehicle into reverse. The solenoid wires into your trailer connector - which connects to your tow vehicle - so that it can detect when you are in reverse. When your vehicle is in reverse, the solenoid ensures that the hydraulic actuator does not activate your trailer's brakes, thus allowing you to back up your rig. To use the lockout feature, you must have a 5-pole flat, 6-way round, or 7-pole trailer connector.

Video Transcript for Titan Brake Actuator - Surge Brake Actuator - T4854120 Review

Speaker 1: Today we're going to take a look at the Titan Hydraulic Disc Brake Actuator with the drop and electric lockout and a 20,000 pound gross towing weight capacity.Now, this hydraulic actuator will activate your trailer brakes when your tow vehicle slows or stops. Basically, when you apply the brakes in your tow vehicle, deceleration occurs and the momentum will push the trailer toward the rear of your vehicle. With the surge brake systems, the actuator is triggered on your trailer as it moves forward, once your tow vehicle starts to slow down. So when this happens, the actuator will contract, meaning this section right here will slide in. That will apply force to the master cylinder right here. This in turn supplies the necessarily hydraulic pressure to engage your trailer brakes.This one is the unique roller design so it does reduce the resistance during telescoping to create a straight-line movement.

You can see the two rollers up here, two down here. When this portion slides in, it rolls on those rollers. And if you notice, they have the grease Zerk fittings on the outside of the rollers. It makes for an easy lubrication. Just put your grease gun on there.

This is a sturdy durable steel construction. It resists bending in any jackknife situations.This one includes the electric reverse lockout. The solenoid right back here, this will let you back up without actuating your trailer brakes. Basically, the electric reverse lockout will automatically activate when you shift your tow vehicle into reverse. The solenoid basically wires into your trailer connector, which connects to your tow vehicle so it will detect when you go into reverse.

When you're in reverse, the solenoid insures that the hydraulic actuator does not activate your trailer brakes, thus allowing you to back up your vehicle.Now to use the electric lockout feature, you must have a five way flat, six way round or a seven way trailer connector. Also if you notice, it has a nice built-in shield over it. This protects that solenoid valve from the elements and from any damage.On the very front here, you can see it has a ball coupler with the trigger latch. It allows for safe and easy coupling and uncoupling. It has a nice circle grip here that you put your finger in.

It makes the latch very simple to use. Just pull back on the trigger to open the ball socket. Once you open the ball socket, drop it onto your ball, release it, and it will lock right into place over the ball.If you notice, this one has a built-in drop to it so this will help match your tow vehicle height. This has a nice corrosion-resistant zinc-plated finish. Up at the top here where the chains attach, this is a breakaway kit that's all included. It is a bolt-on installation. Right down here, you can see the bracket where you bolt it onto your trailer.Application, this is for trailers with disc brakes, gross towing weight capacity again is 20,000 pounds. Tongue weight capacity is 2,000 pounds. The ball size this is designed to fit over is a two and five-sixteenths diameter and this bracket is designed to mount on a straight four-inch-wide trailer tongue.That should do it for the review on the Titan Hydraulic Disc Brake Actuator with the drop and the electric lockout and a 20,000 pound gross towing weight capacity.

Do you have a question about this Brake Actuator?


  • How To Wire the Reverse Solenoid On the Titan 20K Hydraulic Brake Actuator
  • The Titan Hydraulic Brake Actuator part # T4854120 has two black wires that are used for the reverse lockout solenoid, one goes to the reverse light circuit on the trailer connector and the other to a ground. It does not matter which black wire gets run to either of these places. If you have a 7-way trailer connector on the trailer then there is already a port present for the reverse light circuit. If you only have a 4-way trailer connector then you will need to replace this and use...
