EDIT: Nevermind. I ordered the wrong rotors. Looks like these are for two-wheel drive. (Don't drink beer when ordering car parts.)


I know I already have a thread on here about brakes, but it was getting a little unwieldy for the title "quick brake question". Anyway, I was going to begin the rear brake job on my 2000 Jimmy today. I ordered new rotors and loaded calipers from Rock Auto. The rotors that I ordered are Raybestos part number 56725R. According to Rock Auto, they should fit the truck. The thing is, they don't look like the old ones. The drum parking brake drum portion of the rotor is smaller on the new rotor than it is on the old. Can I put these on the truck? Here's some pictures for reference. I left the plastic on the new one in case I have to return it. As you can see, there is about a three-quarter inch difference in size:

I'd say that's a NO. I was going to say that they were for a 2wd as well.

 

Avoid Rock Auto.
I got wrong front hubs for my wifes 99 Jeep
Had a hard time returning them.
Went to NAPA for correct ones.

 

I didn't have any problem returning the rotors. The return shipping for something that heavy is pretty steep, so that was money that was wasted. I learned my lesson though, pay attention to what you are doing when buying parts online.
