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 while the tow vehicle slows. The actuator telescopes, applying force to its master cylinder, which in turn supplies the necessary hydraulic pressure to engage the trailer's brakes.

Because this model does not include a reverse lockout, it is recommended that you equip your trailer with free-backing brakes so that you can drive in reverse without triggering your trailer's brakes.

I regret buying this brake actuator for my boat trailer. This is the exact same actuator that was on the trailer when I got it, but the original was 25 years old and neglected. I decided to buy a new actuator, same as original and also replace the brake lines, baking plate and I even got the drums turned.

Well I go to fill the master cylinder up with brake fluid, open the bleeder screw and try to bleed this unit. It is the most difficult process. This is the absolute worst choice in hydraulic brake actuators for drum brakes on a boat trailer. The ONLY way you can actuate the brakes is to either use a long fulcrum (long piece of angle iron) or chock the wheels and hook it to your truck and back up. This is extremely difficult, cumbersome and just plain antiquated with today's technology. This actuator could certainly be updated with modern design/engineering and make this process much easier.

DO NOT BUY THIS ACTUATOR!


Comments
If you use a longer 2 by 4 it is much easier to get leverage to move the coupler. Another way that you can bleed the brakes more efficiently is with a Hand Vacuum Pump Brake Bleeder item # PTW87030

Works great great price




by:

Purchase experience was as good as i have ever had on any product. items delivered as scheduled. Both items exactly what was ordered. Even return process was easy (my error on one item) and correct item delivered right away. Communication with vendor was excellent. Product descriptions on website accurate which made ordering a cinch. I highly recommend this vendor for any trailer parts needs.




by:

The customer service was excellent! The replacement winch strap I had originally ordered was backordered for months. ETrailor quickly notified me and offered several other options. I chose one of those options and the order was filled and shipped with only a few hours delay. The complete order arrived within a few days, well protected in a heavy duty box, and as described and expected. They are perfect replacements for my old worn out parts. Thanks!




by:

Ordered on Sunday early afternoon and received a notice that same day in late afternoon that the brake actuator had shipped. Don’t see that too often. Item was delivered in a few days and tracking the item was detailed. Brake actuator was a perfect fit in replacing an old worn out titan model 6 7500 lb with a titan 8000 lb. Easy to change out. Took maybe 20 min. Great service.




by:

hello: I am restoring an older boat trailer. I needed a new surge brake assembly. After looking around for days, I came across your website. It was the easiest site to use with great pictures and all the information needed to make my decision in one place. ordering was just as easy. Free delivery and great prices will bring me back

Ordered my trailer hitch come in right
On
time bolted on my trailer worked perfect.. Always have good luck ordering
from etrailer.com




by:

my third Titan Model 6......seems like a new and improved version of the older ones!

Ordered it, they shipped it, all in a few days and arrived in great shape!

Thanks again,

Matt




by:

Very happy with the product so far. It looks to bolt up replacing the old hitch that was on the trailer. I have not had a chance to install T4079200 but I will update after I install...




by:

Just installed my new 8,000LB surge tongue, shipping was fast and installation was easy, great product and works just like its suppose to, would be nice if it had a reverse lock out but because of its design it was easy to make my own lock out.




by:

The brake actuator fits perfectly on my Trail-rite boat trailer. Looks nice also. Will try it on the road next week.




by:

The brake actuator is fine but we were really pleased with the service. The person that took the order was knowledgeable and the order was processed fast and received in no time at all...we will do business with this company again.. Thanks




by:

Exactly what I needed couldn't find it anywhere else except your online store thank you so much. When you stuck on side of road with broken trailer u need it fixed fast. Thanks so much for the fast delivery




by:

The actuator and hitch were received very quickly and look to be exactly what I needed for repair and restoration on a 24.1 Mako. Very well packaged and at the right price.




by:

It took me 5 minutes to put the new coupler on the old trailer. I towed it today and all is well. Thank you...




by:

I sometimes struggle with the coupler, could just be me. Otherwise everything else about it works good. Super easy to install




by:

Very sturdy construction, latch works easily, and actuator woks very smoothly. Would definitely recommend!




by:

work great-just what i needed




by:

It is a little hard to get connected. Requires driving forward and turning some to get the latch to shut. I feel confidant that it is not going to come loose while I am driving.




by:

Product arrived quickly and as ordered. Packaged well for shipping.




by:

Worked great right out of the box. Easy to install and bleed. No problems so far.

  • How to Reset Breakaway Lever on Titan Model 6 Zinc-Plated Brake Actuator T4079200
    On a Titan model 6 actuator like # T4079200 the breakaway reset procedures is as follows: When the break-away lever is engaged, it is in the vertical position. It must be reset before the trailer is moved. First, carefully loosen the pressure line fitting to the master cylinder to relieve hydraulic pressure. Then remove the four bolts that secure the master cylinder assembly to the outer case. The flat front tab of the “U” shaped break-away spring can then be placed in the top notch...

  • How Long of Frame Channel is Needed to Install Titan Model 6 Actuator
    The mounting flange length of the Titan Model 6 actuators is 9-1/2 inches and the additional length the master cylinder adds to that is 6 inches so you'd want to have around 16 inches of frame channel to install a Titan Model 6 actuator like the part # T4079200 that you referenced.

  • Is the Titan Zinc-Plated Brake Actuator T4079200 Suitable for Boat Trailers
    Yes, the Titan Zinc-Plated Brake Actuator part # T4079200 can be used on a boat trailer. In fact, these actuators are actually designed specifically for boat trailers which is why they have a zinc plating so you don't have to worry about about rust/corrosion that is associated with launching a trailer in water frequently. In regards to being submerged, I don't see any issue with this but you don't want the actuator submerged for an extended period of time. If you are just referring to submerging...

  • Why Are Some Trailer Couplers Rated Near 8,000 lbs Available for 2 inch and 2-5/16 inch Hitch Balls
    Typically the larger hitch balls are used in the higher capacity applications, but there is a bit of overlap between the capacities of the 2 inch and 2-5/16 inch hitch balls which is right in the weight capacity range of the two actuators you mentioned. Around 8,000 lbs is where both sizes of hitch balls mentioned are easily within capacity. Above that is when you get into the larger hitch ball size-only territory.

  • Is 8,000 Pound Titan Brake Actuator Sufficient for Trailer with 7,900 Pound GVWR
    The Titan Zinc-Plated Brake Actuator # T4079200 referenced in your question has a weight capacity of 8,000 pounds, so it is rated appropriately and will work well for your trailer that features a GVWR of 7,900 pounds. Also keep in mind that the GVWR refers to the most the trailer can possibly weigh when it's fully loaded. It is unlikely that you will actually load the trailer up to this limit. I have attached a short video demonstration on this actuator that you can also check out.

  • Replacement Titan Brake Actuator for Titan 3241639
    We've checked the part number you gave us before and the replacement for it is the part # T4750820 which is for disc brakes. This one does come with a reverse lock out solenoid. If it has rust all over it I'd consider just replacing the entire thing and starting over with everything new. If you can get me the capacity of your axles and the bolt patterns I can help you pick out stainless steel brake components that won't rust as well.

  • Are Titan Disc Brake Actuators Compatible with Demco Brakes and Brake Lines
    Yes, the Titan actuators like the # T4339720 are perfectly compatible with Demco and other brands of brake assemblies and brake lines. Thankfully all of the setups are designed for the same pressure ratings so they all easily interchange with each other.

  • Solution for Banging During Starts and Stops with Titan Model 6 Actuator on Trailer
    It's a bit hard to tell based on the picture but it does look like you might have an older Titan Model 6 Brake Actuator like our 8K # T4079200. If this is the case then you can use the Replacement Shock # T1242600 to resolve the issues you're having. The banging that you described is absolutely a common symptom of a bad shock component, so this should be all that you need. I have attached a short video review below that you can check out as well.

    Info on your coupler is harder to find but it looks like your coupler is a 8,000 lb rated surge brake actuator. Which for that we have the Titan kit part # T4747220 that is a disc brake actuator designed for disc brake use. Or we have the part # T4079200 which is similar but for drum brakes.

  • Does Titan Model 6 Actuator Need Reverse Lock Out Solenoid
    If you want to be able to back your trailer up without the brakes applying you will need the lock out solenoid part # T4748800 with your actuator part # T4079200. Otherwise your brakes will lock up every time your trailer gets reversed.

  • Is Mounting Hole Spacing The Same On T4079200 And T4853100 Trailer Couplers
    The mounting hole pattern is different on the # T4853100 coupler versus the pattern on the # T4079200 coupler. As you can see in the attached photos the bolt pattern is closer together on the side of the # T4079200 coupler than on the # T4853100. You may wind up with some of the mounting holes in the same place but you will need to drill new holes for some if not all of the holes.

  • 8k Disc Brake Surge Actuator Recommendation
    It sounds like you have a # T4079200 and are looking to convert it so that it will be compatible with disc brakes. If you were using a single axle trailer you could simply ram a screw driver through the back of the check valve in the master cylinder so that the actuator would have higher pressure like what disc brakes require, but since you have a tandem axle trailer this setup would not give you enough fluid displacement to activate your brake assemblies. You will have to upgrade to the...

  • Can a Surge Brake Actuator be Installed on a Swing Away Trailer Tongue?
    As long as a flexible line is used from the back of the actuator to the point where a T fitting will split the lines to the brakes, there will be no issue using the Titan Zinc-Plated Brake Actuator w/ Electric Lockout - Disc # T4747220 with a swing away tongue.

    Based on the issue you are describing the Tie Down Engineering Surge Brake Coupler Model 8000 on your trailer has a shock that is worn out, but since this model actuator has been discontinued there are no replacement parts available any longer. Your best bet will be replacing the actuator. I recommend either the Titan Zinc-Plated Brake Actuator - Drum - 2-5/16" Ball - Bolt On - 8,000 lbs # T4079200 if you have drum brakes, or the # T4747220 if you have disc brakes.

I recommend using the Titan Zinc-Plated Brake Actuator - Disc # T4747200 (for disc brakes) or the Titan Zinc-Plated Brake Actuator - Drum # T4079200 (for drum brakes), which both have 8000-lbs capacities and fit 2-5/16" hitch balls, so they're the same specs as your GDC-80.
