Kodiak offers two types of Rotors and Disc Breaks for the axle applications:

Rotor Only:

This type of rotor typically fits over a standard idler hub.  Wheel studs are pressed into the hub only.  The rotor is frequently wheel bolt piloted and is a loose fit on the hub.  It is held in place by the wheel/wheel nuts.

Integral (One Piece) Hub and Rotor:

In this type, the rotor and hub are cast as a single unit.  Wheel studs are pressed into the rotor.  Bearing races are furnished.

and with the following Corrosion Protection Options:

Corrosion Resistance is important on all types of trailers and of major consideration in salt water or other corrosive environments.

Kodiak pioneered the use of brass fittings, stainless steel guide bolts and sleeves, and stainless steel pistons as standard items in trailer disc brake calipers.

Kodiak rotors are offered with an automotive finish (as machined), E-coated, silver cadmium plated, and stainless steel (not available in integral hub/rotors).

At a minimum, all Kodiak caliper castings and caliper mounting brackets are e-coated with options for silver cadmium plating or an all stainless steel product.

Note: On a stainless steel caliper, all parts are stainless steel except for the fittings, which are brass, and the backing plate on the friction pads, which are zinc plated carbon steel.

With regard to the relative degrees of protection of the various options:

The standard automotive finish offers the least protection (i.e., during a standard salt spray test, rust will begin forming in less than 10 hours).

E-coating offers the best value of protection for over the road use and for fresh water marine (or limited salt water) applications (i.e., during a standard salt spray test, rust will begin forming between 250 and 350 hours).

Silver cadmium plating offers the best value of protection for salt water applications (i.e., during a standard salt spray test, rust will begin forming between 400 and 600 hours).

All stainless steel offers the ultimate corrosion protection in salt water marine applications (i.e., negligible rust will form during a 1000 hour standard salt spray test).
