Today I changed my brake pads on my 2017 Mirage SE(CVT). After putting everything back together I pumped the brakes a few times until it felt like pressing a brick before starting my car which I’ve done many times over the years on my and my wife’s cars. After starting the car I put it in reverse(slightly sloped driveway) and surprise the brakes didn’t engage. I turned the wheel and headed for the grass putting the car in neutral (I thought). When I stopped it was in D or Ds. Once I turned the car off and pumped the brakes again I restated the car and the brakes are good. I have now noticed when I step on the brake when the car is in park there is a click in the shifter. Maybe a safety switch disengaging that I could never hear before? It only makes the click in park. The car shifts normally with no problems. I did try disconnecting the battery and it did not reset. Any ideas?
