Disc Brakes

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.

BrakeRite Trailer Brake Actuator

Titan's complete disc brake kit makes the conversion easy. Designed for tandem-axle trailers, this kit includes not only the disc brake assemblies themselves - along with all the necessary lines, fittings and mounting hardware - it also contains the BrakeRite electric-over-hydraulic actuator.

With a faster response time and more proportional braking than traditional, surge-type actuators, the BrakeRite is perfect for nearly any towing application from light to heavy duty. The system wires into your tow vehicle and senses when and how you apply the brakes. An electrical signal is then sent to the in-cab brake controller to trigger the actuator's pump and motor. Brake fluid is released and sent to the trailer brakes to activate them. The result is real-time braking that, thanks to the electronic proportional valve system, is also smooth and controlled.

Hydraulic Line Kit

Note: If you intend to run brake lines along the axles of your trailer to install disc brakes - as is often done for boat trailers - you will need 2 additional hoses (T4890700 - sold separately) and 2 extra hose clips (T0776400 - sold separately) with brackets (T0776300 - sold separately) to complete the installation.

Just got back from a test drive, and these brakes are the best trailer brakes I've ever used, and I've towed a lot of trailers over the years. They modulate well, and respond to the varying output of the brake controller in my truck exactly as one would expect. That said, there are some issues with the instructions (or lack thereof) included in the kit: 1) The install instructions for the hydraulic lines do not mention disc brakes at all, and the parts list doesn't match up unless you realize that you have a basic kit plus two additional kits all included in the bag. You have to use the install diagram as listed for tandem torsion axles, but there is no mention of this in the instructions. The picture included on the product web page is correct, but is not included with the kit. 2) There are no instructions for installation of the hubs and calipers. Info available in the Q&A on the etrailer web site says the caliper brackets go on with the offset facing out, but I had to install mine with the offset facing in to get the caliper frames centered the best (actually, a no-offset bracket would have been better for my install). I have EZ-Lube axles on my trailer, and it is very important not to drive the grease seal on the back of the hubs in too far, as doing so will result in the seal lip riding on or in front of the grease port on the axle, so grease will be forced out of the seal instead of forced through the inner bearing. I think the kit should come with an instruction or info sheet that addresses these issues. 3) One of the calipers had either a bad seat, or a bad bleeder screw, which caused a leak when I went to bleed the system. I ended up chucking the bleeder screw into a drill, spinning it, and dressing the tapered seat with a file to get it to seal without leaking. This was the only quality control issue I found. 4) The line kit has brackets that are designed to be mounted on a horizontal surface -- my trailer has only angle iron with the edge facing down, so I had to adapt my install to account for this. I ended up removing the brackets from the tee fittings, routing the lines through holes drilled in the angle iron, and cushioning the lines in the holes with short sections of rubber hose over the tubing held in the holes in the angle iron with zip ties on each side. 5) My F-150 has the factory brake controller, so I added the adapter that wires into the brake circuit on the trailer and fools the controller into thinking it's plugged into a trailer with electric brake coils at the wheels. It works great, but again, no instructions -- had to search the etrailer web site for the wiring diagram. Should be in the box with the adapter. All in all, this appears to be a reasonably quality kit (most of the brake parts are made in China), and after I chased down the missing instructions/install info, the install was pretty straightforward. The bad caliper/bleed screw threw me a curve ball, but once I got that sorted, I'm VERY pleased with my purchase. 159495

After having the product arrive at my home and doing the inspection of parts, I soon started the process of assembly. It was very easy to do and handle on my own. The only reason I gave 4 stars is because I was sold the two battery packs, which I didn't need and now stuck with. For the first road test, I took a road trip /camping trip to Big Sur, along the California coast line. Some of the tight twist and turns have you down grade and on the brakes for a 15 mph hairpin turn, the braking worked famously, I am very pleased with the purchase and doing the install. I'll be starting my own v log, and will provide photos of the install, and have told all who are still using the standard brakes to come to the hydraulic side... I tow a 26ft toy hauler with a yukon xl. 426346

The disc brake kit works great and went on perfectly. We put it on a 2008 inForest River travel trailer double axel weighing about 6000 lbs. 357730

  • Titan Disc Brake Electric Over Hydraulic Actuator Not Working with Factory Brake Controller
  • For your Titan Disc Brake Kit with BrakeRite EOH actuator, the issue with the two trucks you are using is the factory brake controllers are not directly compatible with your actuator. You will need the Titan BrakeRite EHB Adapter for Ford/Chevy Integral Brake Controllers # T4846000. I've attached a video to assist. Your other option is to use a different controller like the Prodigy P2 # 90195 or if you don't want to change the factory integrated brake controller the Curt Echo # C51180...

These fit the industry standard number 42 spindles. For this you will need the inner bearing # 25580 and outer bearing # 02475 along with oil seal # 10-63. I recommend you check the bearing diameters to make sure they match your spindles. I've attached a photo and article to assist. For your disc...

  • Recommend Disc Brake Kit For 5,200 lb Tandem Axle Trailer
  • I do have all the parts that you would need to install disc brakes on your 5,200 lb tandem axle trailer, but not as a kit. First, you will need the Kodiak Disc Brake Kit, part # K2R526S, which is a stainless slip-on disc brake kit. We also have a hub replacement disc brake kit, in a dacromet coating, part # K2HR526D. To use part # KSHR526D, you would need to pull apart your hub and make sure you have the correct bearings, races and seals. You will also need to have a 6 on 5-1/2 bolt...

  • Comparing Titan Disc Brake Kits # T4843800 and # T4843700
  • The main differences are Titan Disc Brake Kit part # T4843700 comes with the BrakeRite II SD Electric-Hydraulic Actuator, # T4835700, which is basically plug and play, so faster and easier to install. The kit includes a control module that is compatible with most in-cab brake controllers, wiring harness, breakaway switch and breakaway battery harness. The break-away battery is sold separately as part # T4822100. Part # T4843800 has the EHB actuator # T4813100 and is hardwired and does...

  • Is the Factory Brake Controller on 2017 Ford F-250 Compatible with Electric Over Hydraulic Brakes
  • I took a look at the online owner's manual for your 2017 Ford F-250 Diesel and it does state that the integrated trailer brake controller is compatible with electric-over-hydraulic brake assemblies. You should not need to add any additional parts or adapters to the truck for the controller to work well with this braking system. I have attached an article on installing electric-over-hydraulic brake assemblies to a trailer that you might also find helpful. This article details all the...
