Does anyone know the size diameter of the holes in the picture?

doh!! girling. i ment girling

Story is i left it to soak in a bath of altrans (rust killer), only the crud that came off solidified in the hole's. Removing most of the crud with emery cloth the guide's went in ok, but wanted to clean them up better. A 12mm drill was too small and 12.5 to big, so put down a 31/64 (aprox 12.2mm) now there clean (just lighty skimmed the cast) but the guide pins seem a bit loose and the one with the rubber sleeve hardly touches the sides. And wanted to know if this was exceptable? dont want to risk having flaws on the brakes as accidents may happen.
