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.


Over-the-Hub Rotor

Kodiak's slip-on, stainless steel rotor makes it easy to convert an idler axle to a disc brake axle. Simply place the rotor over your hub. It is most often wheel bolt piloted for a loose fit and then held in place by the wheel itself. With a separate rotor and hub, you can easily repair or replace one element of your brake system without having to junk the whole thing.


Calipers

Kodiak calipers are constructed of stainless steel to prevent flexing and rust. 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 4-bolt brake flange configurations, the included mounting brackets are made of heavy-duty, corrosion-resistant stainless steel 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.

Review from a similar Kodiak Disc Brake Kit


6 Horse Trailer Triple Axle With 20' Living Quarters 18,000# no horses, 24,0000# with horses. Three 8K Dexter Electric Drum Brake Axles. Took off old electric drum brakes (6 of them) without much problem other than "breaking" so many lug nuts. Caliper brackets mounted up just fine and fit perfectly on the spindle bases of the axle. After that, the rotors were installed with new bearings and seals, and again everything fit as it should. The old spindles were grease and the new hubs were oil bath. After researching, I decided to leave the zerks in and pack the bearings with grease even though they were also capable of oil bath. Calipers fitted nicely although some of the powder coating on both parts were inconsistent, although the fit did not seem to cause a problem. The brakes pads are not sticking. I picked the 1600 PSI Carlisle EOH actuator, I guess in part on its shape, and in part the brakes said 1500 PSI min and the 1600 PSI of the unit over 6 tires sounded good. It also was clearly stated as compatible with my 2011 F450 factory controller. It turned out to be easy to wire and mount. I used the suggested gauge wire and moved the controller as far back and close to the axles as I could. I ordered several of the brake line kits and other than the rubber sections, I had to cut every line. The line was 3/16 and the literature suggested that runs more than 20' might be best served with 1/4. But trying to put together all the 1/4 parts proved too difficult so I stayed with the 3/16. Using a hand double flaring tool I had to make about 10 of my own flares, and about three of them leaked...a little, but still leak. Had to redo those. The little 90 degree fitting on the calipers needed to be rotated in my installation, and it was impossible to turn it w/o bending it to being useless. I finally figured out that if the hose was installed first, and then you rotated it, the hose fitting kept the 90 from collapsing. So that all finally got done nicely. Came time to bleed, and it went pretty easily. Had to jack the controller in the truck up to 6 plus to get enough flow to bleed effectively. Mounted the tires up using the old lug nuts but with anti-seize this time, torqued to 150 ft lbs and made sure front bearings greased well... and went for the first road test. On my f450 with truck controller set to EOH and at a setting of about 6, it stops the trailer better than my Freightliner Sportchassis M2 did with the electric brakes. The 6 trailer discs are doing a lot of work. On my first 100 mile trip, the surface never got to over 100 degrees. Granted it was 60 outside, but still, they seemed to cool nicely. They also all read the same which indicated to me that they were all working the same, which was what I wanted, as this to me indicates that pads are not rubbing and all the bleeding is correct. Progressiveness is nice and I'm glad I did not split a gut trying to go after the 1/4 steel tubing. If you crank it up to 8,9 or 10, which I might do if I haul all six horses, I'm confident it will stop great as now it is way too much with two horses. Anyway, I'm happy and satisfied with the project. I wish my brake lines were straighter underneath and that they might need to be supported more frequently, but I'll tweak that soon. You pretty much have to understand how brakes work to pull this off on your own. The few times I wanted to double check things, both e-trailer and Kodiak were pretty much instantly available and gave good help. It took me alone probably close to 40 man hours to completely finish and test, and I'm pretty good at working on things and had proper tools...other than the crappy hand line flaring tool :-) On any significant trailer purchase that I ever make again, I will only get discs. They are at least 40%-50% stronger stopping (maybe more) than the electric drums were, and of course they will last longer, be easier to service, and I think are surely more reliable. Also, the promise of not fading so badly is true. On our first "emergency" red light stop, I was gobsmacked (for my NZ friends) about how fast we could stop and no fade. I can think of no disadvantage other than spoiling you when you use one of your other trailers with electric drums, and wish they were EOH discs. I have full backseat of kids, my bride, and 6 of our horses being towed along, and doing everything you can to STOP, not just pull, is of utmost importance. 29089

Review from a similar Kodiak Disc Brake Kit


Nice quality caliper/Disc set. Hard to find a setup that has rotors without the Hub and Disc as a one piece unit. This Kodiak has a few configuration options for a separate Disc Rotor. Only one problem is that the shipping container had no packing for the protection of the components. The brake caliper hose fittings had broken through the boxes and were exposed outside the packaging. The seal plugs had fallen out of the brass caliper connections. This is a less than acceptable and desirable way to protect the units. 80504

They are still excellent in performance and quality.

Review from a similar Kodiak Disc Brake Kit


The Kodiak brake kit was delivered intact. When installing it , i found that you can not install this brake set on a Road King aluminum I bean trailer. the calipers will hit the frame rails. no matter where i put the caliper, unless all the way on the bottom, which isnt good . So i will have to eat this purchase. Installed the tiedown stuff that wont last 2 years in salt water. I wish there was some information about the Kodiak system needing more clearence between the caliper and the frame.I rated it a good for its not the problem of the brake manufacturer, but the trailer manufacturer for spacing the wheels so close to the frame. 130171





Comments

I just spoke to my contact at Kodiak about the clearance issue you have and he informed me that as long as your bleed the brakes with the bleeder valve pointed up you could then install the calipers in the 6:00 position and they would work just fine.

Review from a similar Kodiak Disc Brake Kit


Note that these do not include bearings, grease seals, lug nuts, dust caps, or bolts to attach the bracket to the trailer. Functionally: These brakes work great. I've had them on a boat trailer with standard surge brakes for years. The e-tec coating has held up better than I would have thought. The rotors get the brunt of the corrosion - the etec wears off due to heat in addition to frictional surface. The calipers still look great though. and really - who cares if the insides of rotors are rusty? I recently bought another set for the second axle, and Kodiak actually put the wrong brackets in the box. The folks over at etrailer worked hard to get the order corrected. 96977

The product was very good and fit as I thought. It would be important to ensure you get the right parts as not every trailer is the same. Also the Kodiak directions are terrible, if you know anything about brakes then it still should be easy, but there are a few things that need to be checked while installing 80365

IM CONCERNED ABOUT THE SIZE OF THE WHEEL LUGS. I HAVE 916 STUDS NOW BUT THE KITS ALL COME WITH 1/2 STUDS. WILL MY 16 INCH ALUMINUM WHEELS STILL BOLT ONTO THE 1/2 LUGS? IM SWITCHING FROM ELECTRIC OVER TO DISC BRAKES.

comment by: BILL K - 05/25/2013

It should not be a problem so long as you have the proper size lug nuts to match the studs on on the rotors. I looked at all of the 16 inch, 8 on 6.5, aluminum wheels that we carry and they are all either for 1/2-20 studs or they will work with both 1/2-20 and 9/16-18. We do not have any of these wheels that will only fit 9/16-18.

Expert Answers about Kodiak Disc Brake Kit - 10" Rotor - 5 on 4-1/2 - Stainless Steel - 3,500 lbs - K2R35SDo you have a question about this Trailer Brakes?


  • Can Electric Trailer Brakes be Used in Salt Water when Adding a Weight Distribution System
  • There are several options for using a weight distribution hitch with your boat trailer and keeping the brakes working properly. If you want to go to electric brakes you can, but you will need to be sure to rinse the brakes with clear water each time you use the boat in salt water conditions. I normally do not recommend electric brakes in wet conditions but it can be done. Electric brakes will corrode much faster and are not available with galvanized parts like hydraulic drum brakes are....

  • Is the Titan Disc Brake Kit # T4843400 Good For a Salt Water Boat Trailer
  • In the Titan disc brake kit, # T4843400, the hubs and calipers are silver cad plated, the actuator is zinc-coated, and the lines are all steel. This is not an ideal set up for a salt water application. The best option would be to go with stainless steel parts. You could start with Kodiak disc brakes, # K2R35S. For 2 axles you would need 2 sets. They fit 14 inch and larger wheels and will fit a hub with a 5 on 4-1/2 bolt pattern. The rotors are the over the hub style. The actuator...

  • Recommend Kodiak Disc Brake Kit To Fit Trailer With 13 Inch Wheels
  • The reason why the Kodiak Disc Brake Kit - 10 Inch Rotor, part # K2R35S, will not fit 13 inch wheels is because part # K2R35S uses a slip on rotor, so the assembly is slightly bigger making the caliper sit out further. You would need a hub and rotor assembly disc brake kit. The caliper and rotors you would need for your trailer with 13 inch wheels is the Kodiak Disc Brake Assembly, part # K1HR35S. You would need to order a quantity of 2 of part # K1HR35S, as it is sold for one side....

  • Availability of Rust-Proof Electric Trailer Brake Assemblies for Use in Sea Water
  • Generally electric trailer brakes are not ideal for use in or near water. Boat trailers generally use either drum or disk hydraulic braking systems to avoid mixing water and electricity, which generally do not like each other. The best brakes for salt water environments are stainless steel disc brakes, such as # K2R35S from Kodiak. It would not be a good idea to mix brake components from different manufacturers since these parts would not have been tested together.
