Review of Kodiak Trailer Brakes K2R712DAC


Today, we're going to review Part Number K2R712DAC. This is the Kodiak Disc Brake Kit with the 13 inch rotor, the 8 on 6 1/2 inch bolt pattern with the Dacromet finish for 7,000 pound axles. Now, these brake assemblies will make it easier to change from an idler axle to a disc brake axle. Basically, when you change the disc brakes, they'll be a little better performance than drum brakes. They'll give you more consistent stopping even at highway speeds and a dramatically shorter stopping distance. Also, the maintenance costs are a lot lower than for drum brakes because you'll have fewer moving parts to maintain, repair or replace on the disc brakes. The Dacromet plating on this will provide superior corrosion resistance for fresh water or salt water use.

They do have a $400 to $600 salt spray rating on them. The rotors right here are a slip on, cast iron, over the hub rotors. You just slide these over the studs, the wheel studs on your hub. They'll fit right over the idler hub and are held in place by the wheel and the wheel lugs. You can remove them easily for maintenance, if needed. There's no need to replace the entire hub and rotor assembly if only the hub or the rotor becomes damaged.

These rotors do have the vented design, as you can see here, that will dissipate the heat quicker. This will help prevent any heat related damage to the rotor. Now, the calipers, they are also Dacromet plated. They are self adjusting for smooth, equal braking. They are made of a cast iron construction, so they do not flex like any aluminum parts. They do have a low drag design.

I pop out the pad there, to show you where the piston is. This piston will retract farther back in the caliper for a cooler running brake. It keeps the brakes off the rotor. The stainless steel piston is 2 1/2 inches in diameter, which is about 30 percent larger than some of the other brands and because of that, it will give you more braking torque than the competition. Then the pads right here, the red parts here, these are a high performance brake pad that they use. Now, the brackets right here, they are a cast iron, male mounting bracket which will provide strength and durability.

You can see the way they're constructed. They have a nice side support design. This will insure that the load is placed on the whole bracket not just on the bolts. Up at the very top, it has some nice, extra embossing for additional thread contact. It gives you a tight, secure mount when you use your caliper guide bolts when you install your calipers to the mounting bracket. If you notice, this bracket is designed for a 5 bolt, brake mounting flange configuration. You do need to have the 5 bolt, brake flange on your axle. If you don't, we do sell a weld on flange that we do sell separately on our website. Now, this kit does include 2 full brake assemblies, 2 Dacramet plated cast iron rotors, the 2 Dacramet plated cast iron calipers, the 2 Dacramet plated caliper mounting brackets, and then the 4 stainless steel, caliper mounting bolts. One thing I do want to note is make sure when you change over to disc brakes, disc brakes do require a higher line pressure, about 1500 psi, when compared to your standard drum brakes. You want to make sure on your trailer to achieve that higher pressure, you're going to have a brake actuator that will have a minimum 1500 psi rating on it. I got a few specs on this. This kit is designed to fit an axle capacity of 7,000 pounds with the number 42 spindle. It does use a wheel size of 16 inches or larger. Again, the bolt pattern is 8 on 6 1/2 inches. This does use the wheel lug size of 1/2 inch. The rotor diameter itself is 13 inches, and again, just to mention on the brake flange, it does fit the 5 bolt brake flange configuration. That should do it for the review on Part Number K2R712DAC, the Kodiak Disc Brake Kit, with the 13 inch rotor, the 8 on 6 1/2 inch bolt pattern, in the Dacramet finish. .
