CURT 52202 RVibrake 4 Portable Flat Tow Brake Control System with Bullseye Wireless Monitor

The CURT RVibrake 4 Portable Flat Tow Brake System adds proportional braking capability to your towed vehicle when flat towing behind a motorhome or RV. Auxiliary braking is required by law in 49 of 50 U.S. states and throughout Canada, and the RVibrake 4 meets those requirements while delivering industry-leading performance and ease of use.

At the heart of the system is a 0.5-second reaction time — the moment your RV's brakes are applied, the RVibrake 4 responds instantly, applying your towed vehicle's brakes in sync for smooth, controlled stops. Built-in brake-lock detection monitors for improper installation, protecting your towed vehicle's brakes from unnecessary wear or damage.

Key Features:

• Ultra-fast 0.5-second braking response for proportional, synchronized stops
• Brake-lock detection prevents towed vehicle brake damage from improper setup
• One-button interface with automatic self-positioning — no manual adjustment required
• Built-in Audio Assistant guides you through complete setup in under 30 seconds
• Includes Bullseye wireless monitor and range extender for real-time braking feedback inside the RV
• Guaranteed compatibility with any make, model, or year of flat-towable vehicle
• Includes hardware for the approximately 5–10% of vehicles that require it
• Thin, lightweight design with a built-in carrying handle for easy portability and storage
• Only the breakaway kit requires installation (approximately 25–45 minutes)
• Backed by a Limited Lifetime Warranty (one-year finish, one-year parts)

Setup is simple: place the unit on the towed vehicle's floorboard, press the single button, and the Audio Assistant walks you through the process. No tools required for daily use. The included Bullseye wireless monitor mounts in the RV's cab and provides continuous, real-time braking status so you always know your system is working correctly.

Constructed from multiple materials with a black plastic finish, the RVibrake 4 is engineered to be the most portable and user-friendly flat tow brake controller available — making every trip safer and fully compliant.
