Note: Disc brakes require a higher line pressure (1,500 psi) than standard drum brakes (1,000 psi). To achieve this pressure, a brake actuator with a 1,500-psi rating is required.

An increasing number of trailer owners are switching over to disc brakes, and with good reason. Disc brake calipers have only one moving part, as opposed to the many moving parts you find with drum brakes. This means that with disc brakes there are fewer parts to maintain, fewer parts to get damaged and fewer parts to repair or replace, thus reducing the cost of maintenance.

Performance increases as well. Disc brakes deliver consistent braking even at highway speeds, unlike drum brakes, which often show a substantial drop in braking torque at higher speeds. In addition, disc brakes offer a much shorter stopping distance than drum brakes.

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

  • Is There a Break-In Procedure When Installing Titan Disc Brake Kit on Trailer
    As 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.

  • Availability of Titan Disc Brake Kit for 7,000 lb Rated Trailer Axles
    We do have 7k rated disc brake kits from Titan as part # THRCM13378DACEK. Since you have a tandem axle trailer you'd need two kits.

  • Titan Disc Brake Kit Recommendation for 2014 Heartland Landmark 5th Wheel Trailer
    From 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...

  • Availability of Replacement Brake Pads for a Titan Disc Brake Caliper
    For Titan replacement brake pads we offer the part # T4870900 which will fit the Titan 10 and 12 inch disc brake assemblies made by Titan. I couldn't find info on the 250 model calipers, but if you have a 10 or 12 inch assembly this would fit and work well.

  • Availability of Corrosion Resistant Disc Brake Kit for a Magic Tilt Trailer
    I 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...

  • Will a Titan Disc Brake Assembly Fit a Heartland Cyclone and HBA-16 Electric Over Hydraulic Actuator
    Titan 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.

  • Replacement 8-Lug Disc Brakes for 10K Sport Boat Trailer
    Thanks 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...

  • Will The Titan Brake Actuator T4750520 Work With Titan Disc Brake Assembly THRCM13378DACEK
    For 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...

  • Disc Brake Kit with Actuator for Trailer with 7000 Pound Tandem Axles
    We 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.

  • Parts Needed to Convert Dexter 8k Trailer Axle to Electric Over Hydraulic Disc
    We 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...

  • Timbren Silent Ride and Disc Brake Kit Recommendation for Lippert 7k Axles
    The 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.

  • Recommended Electric Over Hydraulic Brake Set Up for 2016 Montana 3710FL 5th Wheel
    I 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....
