Brake rotor diameter?
I'm going to do a brake job in the next couple of weeks. I'm cruising Rock Auto for parts. There I see several different rotor diameters.
The truck is a 2002 F-250 4WD. Is the rotor diameter 12.83", 13.03", or 14.53"? I'm looking at Raybestos rotors. Is there a meaningful difference between "Advanced Technology" and "Professional Grade"?
Finally, I see that Hawk pads are well recommended on this site, but not sold at Rock Auto. Where do you recommend sourcing those?
Thanks,
Matt

13.03" is the front rotor
12.83" is the rear rotor
14.53" is front rotor on F-450/550
15.55" is rear rotor on F-450/550
It did remind me, though, that there are specs on this site, so I checked them. I think for 2002 and 2003, though, they are wrong. For previous years, and later years, they show the same as your doc: 13:03" front, 12.83" rear. But for '02 and '03 it shows the same for 4x2, and the opposite for 4x4: 2002 F-Series Super Duty Specifications
I suspect that it is 13.03 front and 12.83 rear for the 4x4 as well, but that the page is wrong.
