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, cast iron 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 cast iron to prevent flexing. Less flex means more braking torque, resulting in smooth, even braking every time. The corrosion-resistant nickel-chrome-plated 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 a 7-bolt brake flange configuration, 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.


Note: These kits will not fit Dexter axles that came from the factory with Dexter disc brakes. They will only fit axles that come with drums or idler hubs.

by:

These work great. Be cautious with 16" wheels though. The caliper will touch the rim but in my case it buffed in the clearance necessary. We used this on a tandem dual trailer and equipped it with the electric over hydraulic pump. Significantly better stopping power than running traditional magnet drums.

This should be standard equipment. Much better than magnetic brakes. After a year in service I have had zero issues.



by:

These are the pics I took when I was done. Took two days to do but we'll worth it. I took pics after first load and now it feels good to actually stop with out wondering if the magnets were going to fail. I appreciate the fast shipping . The only thing I had to pick up was 25 feet of brake line,15 feet was not going to be anough . Other then this. I love it. Thank you very much and God bless



by:

Nice upgrade from electric drum brakes to disc brakes. Clearance on calipers to my 16” steel trailer rims was tight. May upgrade to 17.5” rims in the future.



by:

Great upgrade over the electric over electric drum brakes. Fit and finish was great. Definitely well wort the money for the disc brake upgrade.



by:

I have brakes, electric brakes should be outlawed.
Best thing I ever done was putting theses on my trailer.



by:

Dimensions on caliper are not right , need to do some gridding . It was touching the inside of the rims. Have to move flange back doo to difference in thickness of drum to disc . Have not taken to the hills , but I'm shore it will stop.



by:

Before ordering I submitted a question and received a prompt reply. I followed up and ordered the Disc brake conversion kit and it only took 2 days!! You cant beat the price or door to door service.

  • Can Kodiak 10K Disc Brake Kit # K2R1058D11 Be Used as Replacement Disc Brake Assembly
    The Kodiak 10K Disc Brake Kit # K2R1058D11 is intended to allow conversion of a Dexter 8-288 idler hub for use with disc brakes. It is compatible ONLY with one specific hub, the Dexter hub 8-288 built between February 1990 and August 2009. If your trailer already has disk brakes then you will be better served by installing appropriate replacement parts for your set up. If you want to let me know the bearing set used in your hubs I can help you locate suitable components.

  • How to Convert Dexter 10k Drum Brakes to Electric Over Hydraulic Disc
    We have just what you would need. For idler hubs you would first need to start with the part # 8-214-5UC1 (if you don't have these already) and then to install a disc brake kit specifically for these hubs you would need the part # K2R1058D11 for each axle. This is a Dexter 10k oil bath setup just like what you have. For an electric over hydraulic drum actuator for your trailer you would want the part # HBA16-252-82. That comes with everything electronically. For a 30 foot long tandem...

  • Does Installing Brakes On Trailer without Them Affect Wheel and Tire Position
    We generally recommend you stick with the trailer or vehicle manufacturers when it comes to questions like this, but adding trailer brakes does not change the position of the wheel relative to the axle. Hub/drums have the hub face dimension the exact same as the standard hubs. Maybe there's a difference clearance issue between maybe the frame and other components related to the brakes but the wheel/tire location would not change.

  • Will Disc Brake Kit part # K2R1058D11 Offer More Braking Power than Drum Brakes
    If you would be going from drum brakes to the disc brake kit part # K2R1058D11 yes you would get much better braking power that would engage quicker and also resist brake fade from heat considerably. Now if you have a drum brake setup that would mean you have a drum brake Hydrastar so you would need to replace yours with the part # HBA16 which has the higher pressure rating that disc brakes require.

  • Can Electric Over Hydraulic and Surge Brake Actuators Be Installed At the Same Time
    You ask a very interesting question! You are correct that it is technically possible to have both a surge coupler and an EOH actuator connected simultaneously to the same hydraulic braking setup. You are also 100% correct that any manufacturer's risk management team would probably say no. As I see it, the main concern is the lockout on the surge coupler. If you had an electric lockout on the coupler and if for any reason that solenoid or its power connection failed you would have both...

  • Converting Electric Drum Brakes to Disc Brakes on 9k Axles
    To go from electric to disc brakes you need a disc brake assembly, a brake line kit, an actuator, a brake controller, and a breakaway kit. Since you should already have a brake controller and breakaway kit for your electric brakes, I would go with electric over hydraulic disc brakes because you already have two of the main parts needed and either way you need an actuator. Electric over hydraulic is also better than just hydraulic because you have more control over your braking power due...

  • Will the Kodiak Disc Brake Kit Part # K2R1058D11 Fit a Dexter 10k General Duty Axle
    Yes, the Kodiak Disc Brake Kit part # K2R1058D11 will work with your Dexter general duty 10,000 lb axles as long as you have an 395S inner bearing (2.625" inner diameter) and 387A outer bearing (2.250" inner diameter). These brakes are only compatible with a specific type of hub which is the two piece Dexter 8-288. If you also need the hub then you can use the Dexter Trailer Idler Hub Assembly part # 8-214-5UC1. I have attached a review video of the hub for you as well.

  • Changing Brakes from Hydraulic to Electric over Hydraulic on a Boat Trailer
    There are 2 ways to actuate hydraulic brakes; by either using a surge brake actuator coupler or an electric over hydraulic actuator. A surge brake actuator coupler actuates the brakes by mechanically compressing the master cylinder inside the actuator and applying pressure to the brakes. An electric over hydraulic actuator does the same thing, except it uses the electrical pulse from a brake controller to tell the electric over hydraulic actuator pump when to apply the pressure. If you...

  • Parts Needed to Convert 10k Trailer Axles from Electric Brakes to Electric Over Hydraulic
    First thing you need to do is verify the axles that your trailer has. Hopefully they are a standard axle like a Dexter 10k which the # K2R1058D11 you referenced fits. This brake kit is designed to fit the trailer hub # 8-288-3UC1 which was found on 10k axles made before 2009. Then for a kit that comes with brake lines for a tandem axle trailer you'd want the # HBA16-252-82 and you'd be set. Your controller would need to be compatible with EOH brake like our P3 part # 90195 is.

  • Recommended Electric Over Hydraulic Trailer Brake Conversion for Dual 10K Axles
    The Disc Brake Kit # K2R1058D13 by Kodiak is the brake set that you will need to use for your 10,000 lb Dexter Torsion axles. When it comes to hardware, like the brake line, I recommend going with the HydraStar Hydraulic Brake Line Kit # HS496-252 which will wear better than other traditional brands. These lines are very flexible so the line is easy to maneuver under the trailer. The only downfall is that you cannot cut the line due to how hard and risky it is to do yourself. All you have...

  • Does a Trailer have to have Dually Wheels and Idler Hubs for Kodiak Disc Brake Kit K2R1058D11 to Fit
    Kodiak disc brake kit # K2R1058D11 is designed for 10,000-lb Dexter axles with leaf springs. It will fit either 16-1/2 inch dually wheels or 17-1/2 inch single wheels. So the trailer does not necessarily have to have dually wheels for this kit to fit. The kit fits over idler hubs. Since it fits idler hubs, which are just regular hubs as opposed to a hub with integrated drum, you would need to replace the drum brake hubs with properly sized idler hubs to install this kit.

    Our hub-and-rotor disc brakes kits are offered in various axle capacities including 7000-, 8000- and 10,000-lbs. Since we do not have a 9K kit, which you noted, you can use a 10K kit. Kodiak offers part # K2R1058D11 that works with Dexter hubs that have number 008-288 cast into the hub. This kit fits with 8 on 6-1/2 dually 16-1/2-inch wheels (or 17-1/2 single wheels).
