Dexter K71-G00-45 – 10" Drum Brake Kit with 66 Series Actuator & Breakaway
This comprehensive trailer brake kit from Dexter brings together the core components of a complete hydraulic drum brake system in a single, matched assembly. Designed around Dexter's 10" drum brake specification, the K71-G00-45 includes a 66 series actuator and breakaway mechanism — giving you everything needed to equip or restore a trailer's braking system to OEM standards.
Dexter is the industry benchmark for trailer axle and brake components, and this kit reflects that reputation: components are engineered to work together, reducing the guesswork of sourcing individual parts and ensuring consistent performance across the system.

Parts Desk Insights
Best Use Case: This kit is the right call when you're doing a full brake system overhaul on a Dexter-axled trailer — particularly when the actuator and breakaway are worn or damaged alongside the drum brakes. Buying a matched kit avoids compatibility issues between the actuator and brake components. The 66 series actuator is a surge-style unit, meaning it activates braking automatically when the tow vehicle decelerates — no electric brake controller required. Confirm your trailer's axle rating and drum size (10") before ordering. If you only need drum brake components without the actuator, a standalone drum brake kit may be a better fit. Contact us with your axle serial number if you need help confirming compatibility.
