1. Overview
The briidea Proportional Trailer Brake Controller (Model BR-122) is designed to provide safe and effective braking for trailers with 1 to 4 braked axles (2-8 brakes). Utilizing high-precision motion sensors, it precisely adjusts trailer brakes based on the towing vehicle's deceleration, ensuring a smooth and controlled stop. This controller features a boost function for fine-tuning braking force according to weight distribution, enhancing overall towing safety and reducing wear on braking systems.
It includes advanced safety measures such as overcurrent and short circuit protection, along with fault detection. The integrated LED display provides real-time feedback on settings, output voltage, and boost levels, allowing for timely adjustments. Operation is simplified with intuitive adjustment buttons and an emergency manual switch.

Ensure all connections are secure and properly insulated. Test the connections before proceeding.
5. Operation
The briidea BR-122 offers intuitive controls and a clear LED display for monitoring and adjusting brake settings.
5.1 Digital Display Readings
The LED display provides various indicators:
- Single Decimal Point: Indicates the control is activated, no trailer is connected, and Boost mode is off.
- "b." followed by a number: Indicates Boost mode is active and a trailer is connected. The number represents the Boost level.
- Number (e.g., "5.2"): Indicates Output (Gain) display when the control is activated and a trailer is connected. This shows the braking force being applied.
Image: Examples of the digital display on the briidea brake controller, illustrating how it shows control activation, boost status, and output (gain) levels.
5.2 Adjusting Output (Gain) Control
The Output (Gain) control determines the maximum braking force applied to the trailer brakes. Use the (+) and (-) buttons to increase or decrease the output. Adjust this setting to achieve smooth, synchronized braking between your vehicle and trailer.
5.3 Boost Control
The Boost function allows for additional braking force at the initial application of the brakes, which is useful for heavier trailers or specific towing conditions. Use the dedicated Boost buttons to increase or decrease the Boost level. The LED display will show "b." followed by the current Boost level when active.
5.4 Manual Control
The manual control lever allows you to apply the trailer brakes independently of your vehicle's brakes. Slide the lever to apply brakes manually. This is useful for testing connections or for situations requiring immediate, independent trailer braking.

6. Maintenance
The briidea BR-122 is designed for durability and requires minimal maintenance. Follow these guidelines to ensure optimal performance:
- Regular Inspection: Periodically check all wiring connections for tightness and signs of corrosion or damage.
- Cleanliness: Keep the controller unit clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or abrasive cleaners.
- Environmental Protection: While designed for automotive use, avoid exposing the unit to extreme moisture or temperatures beyond normal operating conditions.
7. Troubleshooting
If you encounter issues with your briidea Proportional Trailer Brake Controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power to Controller | Blown fuse, loose power connection, incorrect wiring. | Check vehicle fuse for the brake controller circuit. Verify power and ground connections are secure. Ensure wiring matches the diagram. |
| Trailer Brakes Not Activating | Loose trailer brake wire connection, faulty trailer wiring, incorrect gain setting, trailer not connected. | Confirm trailer is properly connected. Check blue wire connection to trailer brakes. Adjust gain setting. Inspect trailer wiring for faults. |
| Trailer Brakes Too Weak/Strong | Incorrect gain setting, incorrect boost setting. | Adjust the Output (Gain) control using the (+) and (-) buttons. Modify Boost level if necessary for specific towing conditions. |
| Error Code on Display | Internal fault, wiring issue (e.g., short circuit, overcurrent). | Refer to the manual for specific error code meanings (if available). Check all wiring for shorts or damage. Disconnect and reconnect power to reset. If persistent, contact support. |
| Intermittent Braking | Loose connections, poor ground, damaged wiring. | Inspect all connections, especially ground, for looseness or corrosion. Check wiring for any cuts or frayed sections. |
If the problem persists after attempting these solutions, please contact briidea customer support for further assistance.
