Rear rotor size

Judge Smales · April 8, 2006

I need to change my rear rotors and pads, but when I call to check on parts they ask what size center diameter I have. Is there a way to check what size I have without taking them off? Or has someone who has already changed them know by chance. It's a 02 2500HD with the 6.0 and 4.10 axle. Thanks for any info.

The listed sizes they are telling me are 4.63 or 4.84 center hole diameter.

I guess nobody has ever changed the rear rotors on these trucks!

Your rear rotor is 330mm x 90mm and has the 4.84" Centre hole. The 4.63" centre hole is used on the 9.5" SF 8 lug axle, all the FF axles(10.5" & 11.5" Ring gear)use the larger centre hole. All 01-06 8600GVW and above 4x4 trucks use the same calipers and pads. You might want to think, depending on price to go to an aftermarket Rotor like Powerslot and Hawk Pads. I'm using the Powerslot Cryo Rotors and Hawk pads F&R on my 2500 Suburban and they sure work a lot better than stock and are reasonably priced, Also, if you want better braking use SS brake lines.

Thank you for the rsponse! That was what I was looking for. I am looking at some Raybestos PG Plus rotors and Raybestos Quiet Stop Ceramic pads. I was thinking about using the slotted rotors but had always heard about them warping. I am hoping these will work better than the stock crap has. The truck only has 45K on it and I think that is way to soon for the rear brakes to be shot! Thanks again! Now I can order without having to take it all apart just to check which ones they are.
