Blue my 2007 Chevy HHR

My name is Mary. Ten years ago married my soulmate. Unfortunately I didn't get to live happily ever after. My wife succumb to a heart attack right before COVID. My treasures are the family she left me and Blue which is the 2007 Chevy HHR she left. For the most part I have kept up the normal maintenance on blue, but this time because I'm transitioning jobs for the next few weeks and Blue needs brake pads and calibrators. I was prepared for the pads and rotors, but then the mechanic said calibrators. I just cried, because I need Blue for work. It takes a lot for me to ask for help, but I'm asking now
