Bearing, Race and Seal Information
More and more people are switching their trailers over to disc brakes, and with good reason. 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 substantially shorter stopping distance than drum brakes. Disc brake calipers have only one moving part, rather than the many found in drum brakes. This means that there are fewer parts to maintain, fewer parts to get damaged and fewer parts to have to repair or replace, thus reducing maintenance costs.
The integral hub-and-rotor is made from cast iron, matching SAE specifications. Cast iron is ideal for high-temperature operations and offers a favorable friction coefficient to ensure adequate stopping power. Kodiak's rotors are vented to effectively dissipate heat, dramatically reducing the incidence of heat-related damage. Furthermore, machined disc brakes minimize the chance of contamination between the hub and rotor, resulting in excellent performance and long life.
Kodiak calipers are constructed of cast iron to prevent flexing. Less flex means more braking torque, resulting in smooth, even braking every time. The corrosion-resistant stainless steel piston is 30 percent larger than standard pistons, ensuring shorter stopping distance and increased torque. In addition, the unique low-drag design of Kodiak's calipers allows the piston to retract farther than in most standard models, giving you a cooler-running brake.
Designed for axles with 5-bolt brake flange configurations, the included mounting brackets are made of heavy-duty ductile iron that is embossed to provide additional threading for guide bolts. The added thread strength ensures a tighter, more secure connection between the caliper and bracket. Another unique feature of Kodiak's brackets is the side-support angle, which guarantees that the load is carried by the bracket, rather than the bolts.
I've bought this disc brake kit a year ago and towed over 16K miles. THIS SYSTEM IS AWESOME! No more bucking and chucking or clanging or weak brakes. I tow with 2017 Ram 3500 4X4 and I can stop almost as fast with the trailer on as without. NO brake fade! No squeal! If you're still using electric brakes you're not safe. Totally worth the $$ and time.
Products were easy to replace the old drum system a slight mod was needed to shin out the caliper to line it up onto the rotor but all in all it was a simple replacement all five bolts were able to be secured great looking system.
I changed out my electric drum brakes on my Montana fifth wheel with this hydraulic brake actuator and Kodiak discs rotor system . What a difference this new brake system has made. I can now lock down the trailer tires if needed and drive much more relaxed on the highway knowing I can stop on a dime.
Easy installation and extremely dependable braking power! I use these on a. 33 foot, 16,000 pound flatbed for work. I have 60,000 miles on them and they’re still in great shape. Converting to electric over hydraulic wasn’t cheap, but it was the best investment I made! No brake fade at all, and the stopping power is incredible over the factory electric brakes.
These parts are very heavy duty and fit perfectly on my Dexter 7K axles. The backing plates bolt on in place of the drum backing plates using the same bolts. Bearings, caps and seals are NOT included, but they are interchangeable with the drum brake system that it replaces so parts are readily available for any future repairs needed. At a minimum, you must order new grease seals because it's about impossible to get the old ones out without destroying them. I suggest ordering new bearings too so you aren't gambling on the old bearings still being serviceable. I didn't and lost my bet so I had to make an unscheduled visit to the local parts house where the prices aren't as good as etrailer. The Dacromet appears to be an excellent coating, but since everything is still new, it's too soon to say how it will hold up to the weather. The bolts come pre-treated with thread locking compound so no lock-tite required when installing the calipers.
I had one small problem where one of the brass hose fittings got smashed in shipping due to a combination of careless handling and insufficient packing. The caliper box has a protective pocket that looks like it's designed specifically to protect from this type of damage, but the rotors are heavy enough to defeat that feature when subjected to typical shipping company box banging. etrailer customer service handled this great and got a replacement caliper shipped out same day so I am very pleased with their support in spite of the temporary setback on getting to use my new brakes. I would like to see the kits packaged in a bit more padding and a heavier duty box that can stand up to delivery drivers. All 4 of my boxes were in pretty rough shape to include holes with parts protruding, but the only actual damage was one brass fitting.
So how do they work? Outstanding! I have pulled trailers with electric drum brakes for decades. I have never had a trailer stop itself anywhere near as well as this. In spite of the significantly higher cost for this system, it is well worth the peace of mind knowing that I can stop just as well with the trailer as I can without. I can't count how many times I've used bad words while trying to avoid a collision due to weak trailer brakes. Those days are gone! I plan to do the same upgrade to my other trailer too.
Good kit and the disc brakes are a tremendous upgrade. The only thing I would wish is that they would include the grade 8 fine thread bolts to replace the backing plate studs that are too short.
Nice quality products

Well, its been a little over a year and 14K miles since the install. This is the best thing Ive ever done for towing safety. Steep grades and panic stops are no problem. I let my brother-in-law drive my rig got a day and we did the install on his trailer ad well. He likes them as much as I do. These brakes SHOULD be mandatory on new trailers!
