Brakes fail a low speed, less than 10 MPH. Happen three times. First time there was an accident. I have a dash cam. I had to place the Tahoe into park to get it to stop. Was at dealership for bent push rods for 15 day. I ask them to check the brakes. I guess there were to busy and never checked them (Nucar Chevrolet). https://www.youtube.com/watch?v=OFjiqRWFXuE
