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.

Knowledgeable, patient and willing to help even when my part numbers weren't working! Will did an excellent job working on alternatives to find the right fit. First try, parts arrived on time and fit great. Thank you!


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!


Customer service is amazing I will be ordering all my trailer needs from etrailer


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.


These discs are noticeably stronger than my old drums. I was happy to find this kit came with everything I needed for install.


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.


Brake rotor/caliper kit worked like a charm. Will definitely buy from again!!


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.


Received a wrong part in a brake kit I ordered the correct part was sent and all is good.



The right stuff. The right time. 10/10 would buy again



Product is pretty good. Service was great. Thanks Lisa!!




The best customer service!

  • Disc Brake Kit Recommendation for Boat Trailer With 3,500-lb Axles
    If you have the same boat trailer as you did in your previous question, which has 3,500 lb axles and 13 inch wheels, then the only kit that we offer for your trailer is the Titan Disc Brake Kit # T4843300. The thing about this kit is that it comes with a coupler, which you already have, and the hub/rotors that you were not wanting. This kit includes the combination of a few different kits. Since you already have an actuator, the kits that you would need are the Disc Brake Assembly (2...

    Thank you for all of the info! I did some digging and found out that your older Fulton A60 swing away actuator was actually a UFP A60 actuator on a Fulton coupler hinge like part # FHDPW330300. I was able to speak with my contact at Dexter who said you can make your drum brake actuator compatible with disc brakes by changing out the master cylinder with kit # DX44FR. If you don't already have disc brakes I am linking our selection for you to filter through. If you'd like a recommendation...

  • Replacement Hub and Rotor Assembly with 5 on 4-1/2 Bolt Pattern for 3,500 Pound Trailer Axle
    From my research the hub and rotor assembly you're looking for is for a 3,500 pound axle with a 5 on 4-1/2 bolt pattern. It uses bearings # L68149 and # L44649 and has a Dacromet finish for marine use. If the bearing numbers match you can use # T10HREKITBB for a replacement. You need the complete kit with the rotor and caliper because you can't mix brands between calipers and rotors. The bearing kit that goes with it is # BK2-100

  • Replacement Surge Brakes for a 23.5 Hunter Sailboat Trailer
    If you were looking to simply replace the hydraulic brakes then I recommend the Hydraulic Brake Kit part # AKFBBRK-35-D with the Trailer Hub/Drum Assembly part # AKHD-545-35-G-EZ-K (2). If you were looking to upgrade to disc brakes then I recommend the Titan Disc Brake Assembly part # T10HREKITBB (2). In regards to the brake lines, the HydraStar Hydraulic Brake Line Kit part # HS496-251 would have you covered. Please note, if you upgrade to disc then you'll also need a new actuator like...

  • Parts Needed to Change Electric Brakes on a Tandem Axle Trailer to Electric-Over-Hydraulic Disc
    For a disc brake assembly I recommend going with the Kodiak Disc Brake Assembly # K2HR712DS for 1/2" diameter studs or Kit # K2HRCM1337-9DAC for 9/16" diameter studs. Both of these kits are for 7,000 lb trailer axles. For the inner bearing use part # 25580, outer bearing use part # 02475, and grease seal use part # RG06-070. If you have two 3,500 lb axles on your trailers I recommend the Titan Disc Brake Assembly # T10HREKITBB (2 for each axle) which comes with inner bearing # L68149,...
