Roadmaster 9400 Even Brake Portable Proportional Supplemental Braking System

The Roadmaster 9400 Even Brake is a portable, proportional supplemental braking system designed for flat towing a vehicle behind a motorhome or RV. Unlike fixed "on-or-off" braking systems that apply a single preset level of brake force regardless of stopping intensity, the Even Brake automatically increases or decreases braking pressure in direct proportion to how hard the motorhome is braking — delivering smooth, matched stops every time.

Setup is straightforward: position the unit between the driver's seat and brake pedal, slide the seat forward to secure it, then connect the wiring harness and power cord. The compact, lightweight design fits in virtually all towed vehicles with clearance under the steering wheel and dash. The system transfers easily between vehicles in seconds — no expensive labor or permanent installation required.

Key Features:

• Full-time proportional braking — towed vehicle brakes respond at the same time and same intensity as the motorhome
• Constant self-diagnostic testing — monitors its own performance and transmits any status changes to the in-cab motorhome monitor
• Wireless in-cab monitor — displays system status via LCD text, LED lights, and audio tones
• Emergency breakaway system — automatically applies full braking pressure if the towed vehicle becomes disconnected
• Power Save low battery protection — alerts driver via LED/LCD when towed vehicle battery is low; enters sleep mode if voltage drops too low while retaining emergency braking
• Terrain-Sensing Logic — auto-levels on hills, downhill grades, and rough terrain for consistent braking efficiency
• Automatic brake release — prevents excessive brake wear during extended braking periods
• Adjustable force and sensitivity — fine-tune braking preferences at the touch of a button
• On-board memory — retains adjustment settings even when unplugged
• High-capacity air compressor — recovers quickly and is ready for the next stop nearly twice as fast as competing systems
• Four independently adjustable feet — provide a stable platform in vehicles with uneven floors
• Adjustable brake pedal clamp — fits brake pedals that other systems cannot accommodate
• Made in the USA
