Dexter K71-G00-31 – Complete Trailer Disc Brake System Kit with 10" Vented GalvX Rotors & 66 Series Actuator
Everything you need to add a fully functional hydraulic disc brake system to a single-axle trailer — in one box. The K71-G00-31 bundles Dexter’s Eliminator 10" vented disc brakes with GalvX corrosion-resistant coating, a 6,600 lb rated 66 series surge actuator with backup solenoid, and a complete single-axle brake line kit. No hunting for compatible components separately: this kit is engineered as a matched system.
The 66 series surge actuator activates braking automatically when the tow vehicle decelerates — no electric brake controller required. The backup solenoid disengages the brakes when reversing, preventing the trailer from locking up when backing down a ramp. GalvX-coated vented rotors deliver corrosion resistance and heat dissipation in one package, making this kit well-suited for boat trailers and trailers that operate near water.
Compatible Applications
- Single-axle trailers being equipped with hydraulic disc brakes for the first time
- Trailers rated up to 6,600 lbs requiring a complete surge brake system
- Boat trailers and marine trailers where corrosion resistance is a priority
- Trailers running 13", 14", or 15" wheels
- Applications where a brake controller-free surge system is preferred
What’s Included
- 2 × Dexter Eliminator 10" vented disc brake assemblies with GalvX coating
- 6,600 lb rated 66 series hydraulic surge actuator
- Backup solenoid (disengages brakes when reversing)
- Single-axle brake line kit
- Brake hoses, brass fittings, and attachment hardware
- Brake fluid not included
Parts Desk Insights
Best Use Case: This is the right kit when you’re adding brakes to a trailer that currently has none, or doing a full system replacement on a single-axle trailer rated up to 6,600 lbs. The surge actuator design makes it especially practical for boat trailer use — no brake controller needed in the tow vehicle, and the backup solenoid handles ramp reversing automatically. The GalvX-coated vented rotors are a meaningful upgrade over standard rotors in wet or salt water environments, combining corrosion resistance with the heat-dissipation advantage of a vented design. Note that brake fluid is not included and must be sourced separately. For trailers that already have brakes and only need component replacement, individual brake assemblies or actuator kits may be a better fit than this full system kit.
