Hi im kevin the brake assist warning is illuminated when the system detects a fault.the fault can vary from a pressure sensor to a speed sensor or even position switches.the only way to find the cause is to get car plugged into a diagnostic tool.This allows you to find the reason the system has illuminated the warning and begine testing the component in question.
