Brake Data (BRK)
Monitor the health of every braking system
The Brake Data Parameter Group provides detailed information about the condition and use of the complete braking system.
By combining brake wear, brake activity, retarder performance and parking brake status into one harmonised message, fleet operators gain continuous insight into one of the most safety-critical systems of every vehicle.
Early detection of excessive brake wear or abnormal braking behaviour helps reduce maintenance costs, improve safety and maximise vehicle availability.

- Combined with other Parameter Groups
The default transmission interval is one minute but can be configured to suit the application.
Business Value
The Brake Data Parameter Group helps fleet operators to:
- reduce unexpected brake failures
- improve vehicle safety
- optimise maintenance planning
- reduce workshop costs
- detect excessive brake wear early
- analyse braking behaviour
- improve vehicle uptime
- extend brake component lifetime
Why Squarell?
Unlike manufacturer-specific brake information, Squarell harmonises brake data across multiple vehicle brands into one consistent message format.
Applications only need to support a single interface, while Squarell manages the complexity of different OEM vehicle networks.
This reduces software development, simplifies fleet integration and makes mixed fleets significantly easier to manage.
