If you’re ready to leave electric or surge drum brakes behind, this Kodiak Disc Brake Kit gives you the stopping power you’ve been missing. The 10-7/8" slip-on rotors fit right over standard idler hubs and are held in place by the wheel and bolts, so you can upgrade without replacing the whole assembly. With a 3,500-lb axle rating and a 5 on 4-1/2" bolt pattern, these cast iron rotors deliver smooth, consistent braking even at highway speeds.
Rust is the biggest enemy of trailer brakes, especially around water. Kodiak’s Dacromet-plated cast iron rotors, calipers, and brackets are rated for 300- to 400-hour salt-spray protection, giving them a big edge in both freshwater and saltwater environments. The coating resists pitting and flaking so your brake parts stay strong and dependable season after season.
Dragging brakes and uneven pad wear are common headaches with older setups. These self-adjusting cast iron calipers apply even pressure and retract farther than standard designs, allowing cooler running and longer pad life. Each caliper has a stainless steel piston that’s 2-1/4" in diameter—about 30 percent larger than typical brands—for stronger braking torque and shorter stopping distances.
Vibration and heavy loads can loosen cheaper brackets over time. Kodiak uses ductile iron mounting brackets with extra embossing for more thread contact and a side-support design that keeps the load on the bracket instead of the bolts. The standard 4-bolt brake flange configuration makes it easy to mount securely, whether you’re replacing worn parts or upgrading an existing setup.
Everything you need for the axle swap is included—two Dacromet rotors, two calipers with ceramic pads, two ductile iron brackets, and four stainless steel caliper bolts. The slip-on design simplifies installation so you can handle the upgrade yourself without pressing new hubs. Just add a hydraulic actuator rated at 1,500 psi or higher and compatible lines to complete your disc brake conversion.

Been a year, brakes are so responsive and work so much better will never rely on the old way further. Still working great, never any problem and have never experienced any fade. Switch now and enjoy the added safety.

Sorry about that. I will see if I can get that added to the page to make it clear. Typically the bolts from the previous brakes are used to install the brackets, but it should be made clear that they aren't included with the new parts. What kind of trailer did you install these on?

Disc brake installation went smooth and easy. It would have been better to have the adapter plate mounting hardware. One think to note about these Kodiak disc brakes, the bleeder valve is a two part valve. Be sure to open the 516 hex bleeder screw and not the 38 screw in bushingseat.

I want to thank you again for your assistance in getting me the correct parts for my trailer brake installation. I took three major road trips with the boat last year and the trailer brakes worked flawlessly. The major reasons I installed the braking system were: the overall weight of the boat and trailer in relationship to my pickup 2006 F150 and braking performancesafety on wetslick roads. Both of these concerns were tested last year with wonderful results. I have been telling my friends, with similar trailer packages, to investigate your product. Thanks again,
