Abstract: A brake monitoring system for a machine has at least one traction motor coupled to drive wheels of the machine. An operator input device receives a requested retarding torque from an operator of the machine and sends a signal to a controller that is configured to compare the required retarding torque to a maximum retarding torque available at a particular speed of the traction motor. The controller selectively generates a warning signal based on a comparison of the required retarding torque to a maximum retarding torque available.

Abstract: A leak detection system for an engine air system is provided. The leak detection system may include a plurality of pressure sensors configured to retrieve pressure data from the engine air system, a plurality of temperature sensors configured to retrieve temperature data from the engine air system, and a controller in communication with each of the pressure sensors and the temperature sensors. The controller may be configured to receive the pressure data and the temperature data, compare the pressure data and the temperature data to one or more predefined data trends, and identify a leak within the engine air system based on the comparison.
