Each assembly pairs a single piston aluminum caliper with a patented bimetal aluminum and stainless steel piston, riding on oil impregnated bronze bushings and factory pre-installed stainless steel slider pins for smooth, consistent engagement over time. The caliper is fitted with ceramic brake pads backed by stainless steel plates, delivering steady stopping power while resisting the heat and wear that come with repeated trailer braking.\u003c\/p\u003e\u003cp\u003eThe stainless steel rotor includes venting holes to promote faster cooling during use, reducing brake fade on longer tows. The hub carries a GalvX coating and the mounting bracket is galvanized, giving the assembly corrosion protection suited to trailer environments, including boat ramp exposure. Precision bearings, seals, and grease are factory installed, so the kit arrives ready to mount without additional bearing pack-out. Because this is a G5-caliper assembly, it also serves as an upgrade path for earlier G4 caliper setups, replacing the G4 caliper with the newer G5 caliper and lifetime pads. Each K71-G00-43 kit covers one wheel; a matching kit is required for the opposite wheel position to complete a full axle.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Dexter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e K71-G00-43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor Diameter:\u003c\/strong\u003e 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliper Type:\u003c\/strong\u003e Single piston aluminum caliper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Material:\u003c\/strong\u003e Bimetal aluminum and stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad Material:\u003c\/strong\u003e Ceramic with stainless steel backing plates\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Material:\u003c\/strong\u003e Oil impregnated bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlider Pins:\u003c\/strong\u003e Stainless steel, factory pre-installed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Finish:\u003c\/strong\u003e GalvX coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Bracket Finish:\u003c\/strong\u003e Galvanized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor Material:\u003c\/strong\u003e Stainless steel with venting holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearings and Seals:\u003c\/strong\u003e Precision bearings, seals, and grease factory installed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1 (one wheel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 30 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 13.8 x 12.3 x 6.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 081628820928\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Dexter K71-G00-43 disc brake assembly include?\u003c\/strong\u003e The K71-G00-43 is a complete single-wheel kit that includes a single piston aluminum caliper, a stainless steel rotor with venting holes, ceramic pads with stainless steel backing plates, a GalvX coated hub, and a galvanized mounting bracket.
