75 Duster new brake pads won't fit
I'v run into that i time or two doing brakes in past decades, in my old age.
When using new rotors, and also new pads, sometimes things are just to thick, big, for one another.
Just get a sheet of 80 grit sandpaper on the work bench, and then sand down the new pads to fit against the new rotor.
Easy, peasy. Job done.
