1. A system for notifying a driver of a number of hydraulic pressure support events, the system including
a parking brake assembly;
a human-machine interface;
a parking brake electronic processor configured to generate a command to apply one or more braking components of the parking brake assembly to at least one wheel of the vehicle and generate a request for additional hydraulic pressure support; and
a host electronic processor configured to
receive the request for additional hydraulic pressure support from the parking brake electronic processor;
generate a command to build extra hydraulic pressure at the at least one wheel using a pump motor of a braking system of the vehicle;
provide the command to the pump motor;
increment a count of a counter for each occurrence of a hydraulic pressure support event. wherein the counter indicates a number of hydraulic pressure support events performed;
compare the counter to a threshold value; and
provide an alert to the driver via the human-machine interface when the counter exceeds the threshold value.
