All -

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

 

I use Autoanything, got Hawk Pads and Cyroslot rotors from them. They have a 1 year price match guarantee thing, I've never used it but it's out there.

Here are the brake specifications for model year 2000. I believe 2002 is the same but you will need to confirm. According to this info:
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

 

Thanks, that's a great document. I'd love to see one for 2002, but I couldn't find one.

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.
