Dexter K71-DBC-250-D Brake Caliper, 7000-8000 lb Axle Rating, 2.5 Inch Piston, Dacromet Plated

The Dexter K71-DBC-250-D is a heavy-duty disc brake caliper built for trailer axles rated between 7,000 and 8,000 pounds. It is engineered around a 2.5 inch piston diameter, roughly 30 percent larger than standard trailer caliper pistons, which increases the clamping force delivered to the rotor and improves stopping power under heavier loads. The caliper body is cast iron for strength and rigidity, and the entire unit is finished with Dacromet plating, a corrosion-resistant coating that holds up in both freshwater and saltwater environments, making it a suitable choice for boat trailers and other trailers regularly exposed to road spray, wash-down, and launch ramps.

This caliper is designed to work with 13 inch diameter rotors, so it should be matched with a rotor of that size for correct operation. It is intended as a direct component in a Dexter/Kodiak-style disc brake assembly for axles in the 7,000-8,000 pound range, and is commonly used when replacing a worn or corroded caliper on a heavy-duty single or tandem axle trailer. Precision machining and quality cast iron construction are intended to provide reliable, repeatable braking performance over the life of the part.
