It is making a hard scaping, scubing sound when pressing brakes and sometime will traveling

A couple things to look for. Brake pads wear over time and they have a 'squealer' that is designed to make a noise to alert the driver that the brake pads are getting low. This will sometimes remain in slight contact with the rotor while driving as well. Sometimes instead of squealing you will hear a harsher grinding noise.
It is possible that there is some sort of debris lodged in the brake assembly as well contacting the rotor.
When replacing the brakes, be sure to pay close attention the the sliders and that they are cleaned and lubricated properly as they allow the brake pad to move away from the rotor after braking.
