New Autozone rotors, have them surfaced before installing? I just bought some new AZ rotors for the front but was wondering if I should have them cut before installing or just throw them in there? They are going with new Raybestos Quiet Stop pads, BTW. Thanks!

I can't see any reason you should resurface brand new rotors. Just make sure to wipe them down real good with some brake cleaner to get the grease from the package off.

I think I will have them cut just to be sure. Thanks for the info! Trending Topics

I was swapping rotors once and a guy told me that new rotors can warp just while sitting on the shelf before shipping. I don't know though. Have them checked before I would think. They're gonna warp anyway so I say just slap them on.

We don't have a dial indicator at work, but we do have a digital height gauge. 
It's basically a dial indicator but larger and much more accurate. I am going to do the front brakes at lunch today and measure runout before mounting everything back up. I'll let you guys know how it turns out, but it sounds like it's going to be hit and miss on getting good new rotors.

Well, I checked them out and they were fine. I only did the front brakes today, but still ended up having one frozen slider pin on each side. 
I was able to get one out myself, but had to walk the other one over to a local shop that had a torch so they could get it out for me. Both of the pins cleaned up OK and I re-used them with fresh grease. 
I also found that the dust boots on one of the caliper pistons was trashed, so I'll be taking it off again soon to rebuild it. 
I'll report back what I think about the setup after I do the rears this weekend and get a chance to break them in and drive it a little bit. This will be with Autozone rotors in the front, re-surfaced stockers in the rear, and Raybestos Quiet Stop pads all around.
