My trailer has the EZ-Lube axles. I upgraded to disk brakes and got the parts and installation from Performance Trailer Braking. They were attending the international rally put on by my trailers manufacturer and offered a discount. Note that you need to order the parts based on your specific axles. In my case, they were unable to do the install at the rally because they couldn't get the right parts, but gave me the discount and did the install while I was traveling. Install was done in a state park. They will come to you to do the work. Their tech was easy to work with, installing the pump/actuator where I wanted it and giving me training working on the brakes.
I've had zero issues related to their work. In retrospect, had I been more comfortable with brake/wheel work, I could easily have done the install myself. It took the tech about 6 hours start to finish.
I can't help with the Kodiac system. If you decide to use Performance, PM me, using me as a reference will get you a discount.
