Kodiak Offers Two Types of Rotors and Disc Brakes:

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.

Points To Consider
  • Removal of the rotor can be accomplished with little effort once the wheel and caliper have been removed.
  • If either the rotor or the hub require replacement, the good component can be retained and re-installed, while the faulty component are replaced. With an integral (one piece) rotor/hub, the complete unit must be replaced.
  • Installation of an “over the hub” rotor effectively increases the overall hub face to hub face dimension by approximately 1/2”.
  • Wheel bolt thread length should be a consideration when installing an “over the hub” rotor.
  • Easy to convert an idler axle to a disc brake axle with an “over the hub” rotor.

Integral (One Piece) Hub and Rotor

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

Points To Consider
  • Hub and rotor are machined together. This minimizes rotor runout.
  • Hub and rotor are balanced as one unit, which offers a smoother ride.
  • Simpler and easier to install when retro-fitting and/or upgrading from drum brakes.

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 is zinc plated carbon steel.

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

Image 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).
Image 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).
Image Dacromet coating offers the best value of protection for salt water applications. (i.e. during a standard salt spray test, rust will begin forming between 400-500 hours)
Image 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).
