Quick question about resurfacing the rotors. I just ordered the Hawk pads for the rears and since by rotors are a tad bit warped and was thinking of having them resurfaced. I've had worse on the Speed 3 and refurfaced with no problems. So my question is is it safe to resurface the rears? Like I said before, my Speed 3 front were warped 3x worse than these on the cobalt and had no issues after I resurface and installed new pads.

As long as you dont pass min thickness

It's a good idea to resurface when you put new pads on anyway.

How much they charge you to resurface them?

I'm not sure on the SS/tc, but my 2.4L has non-vented rotors on the rear.
Its pretty simple to cut rotors but from personal experience and talk from coworkers
cutting rotors makes them slightly thinner which will cause them to warp a little easier.
The fronts are vented which will dissipate the heat a lot quicker than the rear (non-vented).
While the rear doesn't do as much braking as the front, if you have the money just pick up
a new set of rotors.

Even if it is not warped, it is a common practice amongst many "old school" mechanics to take some metal off the rotors. It give the new pad a "new" rotor surface to grip on. Think like a clutch/flywheel combo. If you leave the rotor worn from the old pad it can cause premature wear on the new pads.

You can get brand new Centric high quality (Premium) rotors from Rock Auto for $111 SHIPPED (to Ca for me). Not worth it to turn em for that price. Get new rotors...in any case do NOT put on new pads without a fresh surface, especially the way the stock pads hammer the rotors.

Kind of an interesting question - I can tell what I do on the Camaro, which is - nothing.

I probably should emery cloth the brake surface, but I don't. I would agree w/ that old school thougt that any time there are new pads ( or shoes !! ) the brake surface should be freshened, but do I do it that way all the time ? nah.

Example : The Land Cruiser in the sig - I don't tear the front end apart to get the rotors off to have them turned. It's a full time 4 x, and that would be a bigger job that it sounds.

If the rotors are free floating on the Balts ( held on only by clips over the wheel studs after the lug nuts & wheels are removed ) then there really would not be much of an excuse.

If there really is a way to resurface a drilled and/or slotted rotor, I'd like to know what it is.

Thanks fellas for the info. I know it's a given to resurface rotors when adding new pads. I just wanted to know if it was a good idea to do that to the stock ones. Seeing how the FAIL is with the rears ones. Think I'm just gonna order some R1 concepts when I get paid an March and wait to install both the pads and rotors at the same time and call it.

I got my rears re-surfaced, it's a good thing to do.

Oh my bad misunderstood the original question. Yes it is generally perfectly fine to turn the stock rotors as long as they don't get too thin. There is a spec put out by gm which will tell you how thin you can get it.
