The most important part of your marine trailer is the braking system. Because while quick acceleration will give you a thrill, quick deceleration will save your life. Whether you're building a new marine trailer from scratch, or refitting a marine trailer on which the brake systems on the wheels are completely shot, this complete brake kit is the best way to go. With all the components listed below included, you can save yourself the hassle of ordering each part individually. This kit is designed to replace the DB35 kit manufactured in the United States by Unique Functional Products (UFP), which has 9.6-inch rotors and 5 studs (onto which the lug nuts screw, to hold the wheel on). Buying this kit from SkipperMate Marine is a great choice. We've been supplying Australia and New Zealand with high quality marine trailer components for 20 years, and we've been around that long because we're devoted to providing great customer care.
