Features to know about
Upgrade from Drum to Disc: 13" Dacromet-Coated Hub and Rotor Assembly
If your old drum setup is fading or dragging, this Dexter disc brake assembly gives you a major step up in stopping power and consistency. The 13" hub-and-rotor design delivers solid braking torque even at highway speeds, with fewer moving parts to maintain than drum brakes. It’s built for 7,000-lb axles and wheels 16" and larger, and its 8 on 6-1/2" bolt pattern makes it a direct fit for heavy-duty use.
Built for Harsh, Wet Conditions: Dacromet Protection with Bearing Buddy
Saltwater, rain, and road grime can ruin unprotected brakes fast. This setup uses Dacromet plating for superior corrosion resistance and carries a 500-hour salt spray rating. The included Bearing Buddy protectors keep water and dirt out while giving you easy access to grease fittings. It’s a durable choice for anyone who regularly tows in wet or coastal conditions.
Simplifies the Swap: Pre-Assembled Components Ready to Mount
DIY installers will appreciate how complete this kit is right out of the box. It comes with the hub-and-rotor assembly, cast iron caliper, mounting bracket with hardware for the caliper, plus races, bearings, grease seal, and Bearing Buddy pre-fitted. The bracket attaches to a standard 5-bolt brake flange using hardware sold separately—no guesswork or half-day shop jobs required.
Delivers Consistent Stopping Every Time: Hydraulic Pressure Setup
Disc brakes need higher line pressure than drums—1,500 psi compared to 1,000 psi—and this setup is designed for that hydraulic performance. Pair it with a brake actuator rated at 1,500 psi for smooth, repeatable braking under load. Once installed and bled properly, the system offers reliable stopping power whether you’re cruising level roads or hauling down long grades.
Engineered for Secure Fitment: Precision Bearings and Races Included
Everything about this assembly is built around exact bearing compatibility. It includes inner bearing 25580, outer bearing 14125A, inner race 25520, outer race 14276, and seal 1707200 (2.250" ID / 3.376" OD). With this precise setup and a 3-year warranty behind it, you get a solid fit that’s made to handle real towing miles without the hassle of mismatched parts.

This was an excellent decision to convert my electric drum brakes to these titan disc brakes. After adjusting my drum brakes i would have to use the highest setting on my trailer brake controller. Now with the disc brakes i am only on 5 out of 10 and i get excellent braking performance. The braking is smooth and consistent on each of the 4 trailer wheels unlike drum brakes. It is incredible that they don’t make this a standard for trailer brakes. It has made pulling a 10,000 lb skid steer much safer for me and my business. I would love to say that everything is perfect but it does have some flaws. First i had a clearance issue on my trailer when installing. The bottom bolt for the caliper was too long to get started , so i had to shave off about 3 threads with a grinder to get it in between the frame of my trailer and the caliper. Also the top bolt on each caliper was damaged after some use because it was contacting the I beam of the trailer ( im pretty sure this is unique to my trailer. Trailer World 25’ 14k gooseneck). Etrailer sells the replacement bolts for the Kodiak calipers which also work for the Titan. After the clearance issue the only other problem i had was the threaded bearing buddy dust cap. Loosening and falling off on the road. This exposes your bearings to dirt and dust and also slings grease all over your trailer, tires,and rims. A smarter design would be to have a flat surface on the bearing buddy so you can tighten it better or a set screw in the hub to hold it from coming off. I have just ordered 2 new bearing buddys from etrailer. Hopefully they will fit. Make sure you use some kind of thread locker or other adhesive to keep them from backing out
If it wasnt for this i would give 5 starts

perfect fit! The only down side (which isn't a big deal) is in purchasing two of these sets, one had red pads and the other was silver. Symmetry would have been nice.

I received an incomplete order with missing calipers, etrailer was unable to get me the part in a timely manner and blamed it on the manufacturer Dexter. This caused me to spend the Labor day week with my kids and grand kids at the lake minus the ski boat. This order is being returned. Poor customer service!!!

I expect 2 rotors. Who would change just 1 side of an axle. Would have purchased a completely different product had I known for that price it was only half of what I need. I see now that the picture only shows 1 rotor, but it never even crossed my mind that someone would do only half the job.

I ordered this kit so to have spare parts for the Titan disc brake kit which I installed from my previous order. From past experience I discovered it is always good to have these parts available and on hand for when a wheel bearing destroys itself on a Sunday morning 500 miles from nowhere and a person should be prepared with the knowledge how to do this work on the shoulder of the road by ones self! So much for roadside service it just doesn’t work for all locations as those insurance company’s advertise.
In short even with the best of quality parts(which I am happy to say etrailer has always supplied me with) there will be failures which can put a big hole in vacation budget!
This kit was just as advertised and includes everything to replace one complete hub assembly ,bearings ,disc brake and rotor (just what you would need for that roadside repair).
Also many thanks to the folks at etrailer for delveloping such a good Hydraulic disc brake kit to replace the horrible electric brakes that came with our trailer.
They never really worked well no Mather what special adjustments or service that was performed on them! The trailer manufacturers should be ashamed for ever using them in the first place and for safety’s sake electric brakes should be outlawed!

The brake system is awesome. The best trailer brakes I have ever owned. Unfortunately I had a rock kick up, jam between the trailer frame and brake causing damage to one assembly. The people at etrailer are great to deal with and everything I needed arrived quickly. The entire swap over took less than an hour as the setup is so simple.

This brake assembly has been working great for me. It was easy to install (see install video on etrailer site if needed) and gives me great piece of mind. This brake assembly has seen over 1500 miles so far for me.

Overall quality of product was fine, however, they didn’t include the brake caliper in the kit. I emailed etrailer and received a quick response but it’s been almost a month and they still haven’t sent me the caliper that I paid for. Pretty lame considering they pride themselves in customer service.

Hi Carl. I just wanted to let you know Dexter is getting a replacement caliper sent out to you. It's going FedEx Ground out of Atlanta, so it will take a few days, but it is on its way. I know this wasn't a great experience with us, but if you do need anything else, just let me know.

This is a great product and was exactly as advertised. The shipping and packaging was done very well and arrived to my door in perfect condition. Shipping was fast and the price was amazing, if I was to source the parts locally it would have cost over triple the price. Thank you for your service.

Brakes were great for almost a year, then one of the pistons started sticking causing me to have to do an emergency repair on the side of the road. Luckily I caught it soon enough that I think the hubs and rotor are ok. Brakes have been used 95% in freshwater with only one trip to Florida where they were immediately heavily rinsed with fresh water.

- Timbren Silent Ride and Disc Brake Kit Recommendation for Lippert 7k AxlesThe Timbren Silent Ride 7k system part # TSR7000T05 would be a great solution that doesn't quite break the bank like the MorRyde would. Then for a disc brake kit you'd want the part # K2HR712D which is a 7k kit that will fit your Lippert 7k axles well. You will also need the bearings part # 25580 and # 14125A for each hub and then seals too as part # RG06-070. This is a Dacromet coated setup which will fight corrosion well.
view full answer... - Parts Needed to Convert Dexter 8k Trailer Axle to Electric Over Hydraulic DiscWe have all of the parts needed to convert an 8k trailer axle to disc brakes but we don't have it as a single part number like we do with some of the other axle capacities. So the best actuator is the Hydrastar as we have found that they are by far the most reliable and quickest reacting. For that you'd want the Hydrastar kit part # HS481-8067 which also comes with the breakaway kit, battery and wiring needed. Then you'll need the brake line kit part # HS496-252. Then for the actual axle...
view full answer... - Replacement Brake Pads for Titan 13" Disc Brake AssemblyI was able to get the Replacement Brake Pads for Titan 13" Disc Brake Assembly part # DX65FR added to our site for you so they are now available to purchase. These will be a direct replacement for the Titan Disc Brake Assembly part # THRCM13378DACEK.
view full answer... - Replacement 8-Lug Disc Brakes for 10K Sport Boat TrailerThanks for reaching out and sending your photos! From what you sent in I recommend checking out the Dexter Disc Brake Assembly # THRCM13378DACEK as it has the matching 8 on 6-1/2" bolt pattern, uses a heavy duty Dacromet finish, and comes with the bearings and seal needed to complete the installation (25580 inner bearing, 14125A outer bearing, and seal with 2.250" ID and 3.376" OD). This can be used as a left or right assembly so you'll just order 4 of these so you have 2 for each axle...

- Availability of Corrosion Resistant Disc Brake Kit for a Magic Tilt TrailerI can't safely recommend/guarantee that your current rotors would work with a Kodiak caliper. There is a chance they might, but since they weren't designed to work with each other there is a chance the two might not be compatible. The best recommendation I can make would be to go with an entirely new system like the part # THRCM13378DACEK that has a Dacromet finish that will fight rust. This system has a 500 hour salt spray rating which means it takes 500 hours of being spayed with saltwater...
view full answer... - Availability of Titan Disc Brake Kit for 7,000 lb Rated Trailer AxlesWe do have 7k rated disc brake kits from Titan as part # THRCM13378DACEK. Since you have a tandem axle trailer you'd need two kits.
view full answer... - Recommended Electric Over Hydraulic Brake Set Up for 2016 Montana 3710FL 5th WheelI was able to confirm that your Montana 3710FL uses tandem 7000 lb axles. A 7K axle would typically have an 8 on 6-1/2 wheel bolt pattern and the spindles would be compatible with a 25580 inner and an 14125A outer bearing. You'll want to identify the inner and outer wheel bearings used by your current hub/drums. Let me know if your hubs uses a different outer bearing. If your drums use the 25580 inner and 14125A outer bearing, I'd recommend the Kodiak 13 Inch Hub/Rotor Kit, part # K2HR712E....
view full answer... - Will The Titan Brake Actuator T4750520 Work With Titan Disc Brake Assembly THRCM13378DACEKFor a surge style set up, the Titan Disc Brake Actuator # T4750520 will definitely be a good actuator. This will also work in unison with the Titan Disc Brake Assembly # THRCM13378DACEK without issues. This does utilize an electric lockout making backing up a lot easier as well. If you wanted to go with an electric over hydraulic set up, the HydraStar # HBA16 would be a great option. That being said, to activate an electric over hydraulic actuator, you will need a brake controller like...
view full answer... - Is There a Break-In Procedure When Installing Titan Disc Brake Kit on TrailerAs long as the brakes are bled properly there's no need for any other type of break-in procedure when installing disc brake kits like the part # THRCM13378DACEK that you referenced.
view full answer... - Disc Brake Kit with Actuator for Trailer with 7000 Pound Tandem AxlesWe do carry all of the pieces individually but we don't have a Titan brake kit that includes an actuator rated for 7,000 pound axles. You can use most of the parts that are included with the lower rated kits: BrakeRite II, part # T4835700 Brake Lines and Fittings, part # T4830000 Breakaway Kit, part # T4822100 Then for the higher rated brakes use part # THRCM13378DACEK.
view full answer... - Will a Titan Disc Brake Assembly Fit a Heartland Cyclone and HBA-16 Electric Over Hydraulic ActuatorTitan disc brake assembly # THRCM13378DACEK will fit your trailer if the existing hubs use inner bearing 25580 and outer bearing 14125A and if the wheels have an 8 on 6-1/2 bolt pattern. They are compatible with the HBA-16 electric over hydraulic actuators such as # HBA16. If you have different bearing numbers or wheel bolt pattern let me know and I can see what else we have that can work.
view full answer... - Titan Disc Brake Kit Recommendation for 2014 Heartland Landmark 5th Wheel TrailerFrom talking with previous customers who have the same trailer as you we were able to determine that your trailer has 7k Dexter axles. So for a Titan disc brake kit you would want the part # THRCM13378DACEK. This is a 7k rated disc brake system that will fit a Dexter 7k axle. This is an individual setup though so you would need to order a quantity of these based on how many wheels on your trailer that you are adding disc brakes too. So if you have a tandem trailer you would need a quantity...

Sorry to hear the issues and service you received, Carl. We do pride ourselves on our customer service, but it looks like we dropped the ball here, and for that I sincerely apologize. We don't currently have any stock for this, but I am contacting Dexter to see if they have any of the calipers to ship out to you. I will let you know as soon as I hear anything from them. Again, I apologize for this continued inconvenience and I will do my best to try and make it right.
