Dexter 023-499-00 10 Inch Left Hand Hydraulic Trailer Drum Brake Assembly

The Dexter 023-499-00 is a complete 10 inch hydraulic trailer drum brake assembly built for the left-hand (driver's) side of the trailer axle. It is designed to work with hydraulic brake actuators that do not include a reverse lockout, so the assembly can reverse freely without the actuator engaging the brakes. The unit measures 10 inches wide and 2-1/4 inches thick, with a 3 inch center hole diameter and 44 square inches of pad lining area for consistent stopping power. It fits most trailers running 13 inch, 14 inch, or 15 inch wheels, making it a common replacement across a range of boat, utility, and cargo trailer axles. The assembly comes with a black-painted finish for corrosion resistance during outdoor and marine trailer use.

Because this is a left-hand assembly, it must be paired with a separate right-hand assembly (a different part number) for the opposite side of the axle -- installing the wrong side will not seat or actuate correctly. This complete assembly simplifies replacement by supplying the full brake unit rather than individual components.
