Cause 1: Trapped dirt or rust on brake pads and rotors Probably the most common cause of noisy brakes, especially at low speeds is brake dust, dirt or rust on the brake pads and rotors. These contaminants can get trapped between the rotor and brake pad surfaces causing a squealing or grinding noise when braking.

Apply some grease in all the contact points to see if that helps your brakes to stop grinding. First, remove the brake pad from the calipers, and then apply grease everywhere, so that every contact point including the backside of the brake pad and caliper carrier are covered in a thin layer of grease. This could smooth out any grinding touch.
