Brackets like this are designed to attach to the backing plate, and hold the caliper in place over the brake rotor. Every time the brakes are engaged, the caliper and the mounting bracket both have to withstand an extreme amount of force. This mounting bracket is made entirely of stainless steel, so you can be confident every time you step on the brake pedal. Stainless steel is not only extremely strong, but it's an ideal choice for marine trailers because it naturally resists corrosion from both fresh water and sea water. This bracket is designed for use with 10-inch rotors, and any calipers that are made by either Deemaxx or Kodiak. SkipperMate Marine is a multi award winning marine dealership which provides high-quality products, and outstanding customer service. If you live in Australia or New Zealand, there is no better source that you can choose for the marine trailer parts and accessories you need.
