After doing a search on the bolt size to remove the front calipers on a 2001. 5 there was never a definite answer. Torx 50 or 16mm 12 point. Tried a 45 too small, 55 to big. Before I go out and buy one does anyone know whitch size it is. 90,000 on the origonal pads and still some left. Bought new pads 4 years ago and figured its time to change.
