So i bought a used 2019 Silverado 1500 and thought I would check my brakes just to see how much meat they had because I'm new to the brake wear sensor and just wanted to see for myself. After inspection I put everything back together and noticed I had my brake light come on along with "break system failure", check ESC, check trailer brakes and had my speed was reduced to 43 MPH. I limped it over to O'Reilly auto parts and had them put the code scanner on it. The O'Reilly employee told me he had seen this time and time again. Apparently there is a valve that you open on the brake line before pushing the piston back in on the caliper when trying to put brake pad back on. The employee cleared the code and I haven't had any issues since.
