Disc Brakes

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.


Integral Hub-and-Rotor Assemblies

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.


Calipers

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.


Mounting Brackets

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.

Converted my 2010 Raptor 3912lev tri-axel toyhauler to disc brakes with the kodiak kit and hydrastar actuator. Install was very straightforward and the e-trailer folks were extremely helpful in confirming that this kit would work for my trailer and helping with questions while I was installing. Stopping power is excellent, glad I invested in this upgrade --- the fifth wheel really stops the truck now.

Jason-did you use 316 brake line out of the hydrastar or 1/4 ? I see you have tripple axle and I have only a tandem 5th wheel but have read were some people sense a delay with the electric over hydraulic that went away when they switched to a 1/4 line. Also did your factory in cab controller work with it well? if so what type and year is your truck. Thanks Joe

Jason

12/21/2015

Hi Joe - I used the 3/16 brake line kit from kodiak. I will say that I do notice the slight delay that is documented, but it doesnt bother me and I havent given much thought to trying to eliminate it because the overall braking is so strong. As for my truck, I have a 2006 F350 with the integrated brake controller. The kodiak documentation states that this controller is compatible. The controller works great, with the one exception being that sometimes I get a random chime from my truck when I hit the brakes. No message pops up on my dash, but it will do it from time to time. I think it has to do with the varying amount of voltage it is sensing from the EOH pump. If youre familiar with Fords, it is the same chime that goes off whenever a message appears on the dash computer such as low fuel, or trailer disconnected. As I said I am overall very pleased and glad I spent the money. I have no worries about being able to stop the truck/trailer on the highway.

Jason, did you use the trailer break away switch that came with your unit or did you have to buy something special? I have a 2007 Montana and am about to do the same conversion to Kodiak disc brakes and the only unanswered question is about the break away switch.Thanks,Dave W.

Jason S.

2/12/2016

Hi Dave -I followed the wiring diagram and used my existing break-away switch. It just needs to be re-wired per the instructions included with the EOH pump. K

Installed on my 2009 Keystone Fuzion FZ302. I was very impressed by the fit and finish. What a difference in braking!! I don't think I will ever own a trailer with electric drums again. I was able to install all four in about 6 hours. This was taking my time to ensure all clearances were exact. The only thing I ran into was the sticky weights on my 16" wheels just touched the caliber. I had the wheels rebalanced with clip weights on the inside and we are now all good.



by:

I had finally decided after much research to upgrade to hydraulic brakes on my 38' Montana Fifth Wheel. Etrailer provided some much useful information and instruciton along with their quality products. I replaced all wheel/hub assemblies with new bearings and seals. Installed the Kodiak disk brakes and hydraulic lines.
I purchased a different controller than the one they offered but the job went reasonably well because everything fit as it should. We traveled South last Winter to Arizona from Washington and I was very impressed by the performance of my new brakes. if I bought another rig I wouldn't hesitate to install these brakes they work so much better than standard electric.

Ive put about 9,000 miles on the 5th wheel since converting to the hydraulic disc brakes and Im so much more confident in the handling and performance of the brakes and suspension. It was not the easiest job to do but I took my time and did it right so I know I set everything up correctly. Now I have real stopping power, no fade. Good products, durable and built to last.

Super fast shipping and items received in good condition. Items are 100% as described and although I have not installed them yet I am sure they will work just fine. So happy with etrailer that I have already placed another order.

Great product !

Easy to install worked perfect



by:

Having hydraulic disc brakes on my trailer is awesome smooth consistent stopping much safer than electric drum brakes



by:

Installed complete kit with rotors and actuator ,system works great only had issue with not receiving full order but customer service took care of issue and got the rest of the order out to me.



by:

The product is good, what I expected from Kodiak. Everything else about the transaction terrible. Purchase your parts someplace else. Ridiculous wait times when I called in, was given incomplete and not correct answers. Specifically asked to speak to a specialist or technician was refused. Purchased most the parts I needed from a competitor. Decided since etrailer had the Kodiak parts in stock, with the delivery quick I would try one more time. Huge mistake, parts not in stock as shown. A simple phone call could have resolved a question, nope an email was sent delaying delivery.
etrailer is local for me, was always recommended by me as I traveled across the country. NO MORE.



by:

very good product high quality I would recommend to anyone looking for a good braking system at a fair price

Finally received this disc brake kit for 1 axle after 2 weeks and it appears to be as advertised.

  • Best Parts Needed to Convert 2014 Montana Fifth Wheel to Electric Over Hydraulic Disk Brakes
    Disc brakes have to have a hydraulic element to activate them which means there isn't strictly an electric only option.

  • Recommended Parts to Convert Electric Brakes on 5th Wheel to Electric Over Hydraulic
    We don't offer a complete kit for 7K axles, but we do have hub/rotors or slip on rotors that could work depending on the inner and outer wheel bearings or wheel bolt pattern your hubs currently use. For instance, if your hubs use a 25580 inner bearing and a 14125A outer bearing, two of the Kodiak # K2HR712E kits which include the hub/rotors, calipers and caliper brackets would be a good start. The bearings and races are included. You'd also need a line kit like part # DM5425 and an electric...

    Your current brake mounting flange hardware would work to install the mounting flanges of the Kodiak Disc Brake Kit # K2HR712E. The bolt length should be just fine from your mounting flanges. We have installed these kits on several trailer here and have never had to get longer bolts for the flanges. This kit will also fit the spindle you have on your Dexter D52-8 axle.

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....
