Hi, I have a set of what I believe to be ST170 brake calipers. They are made by ATE and have 615 or 616 cast into them depending upon the side, while the carriers have 24 cast into them.

I also have some Mintex MDB2272 pads, which should fit ST170 and Fiesta ST. While these pads are the correct width for my calipers, they don't look like they will fit without some serious filing back. I was just wondering if this is usually the case, or if these ST170 calipers (which I have just spent a fortune having refurbishes) aren't actually ST170 calipers at all. Which would make me very unhappy.

Any help / advice gratefully received!
