They are brake discs.

New discs for your car should run about $50 each for the standard
replacements. The pads should run another $50 for the axle-set. This puts
the repairs at $150 plus the labor. (All prices are USD). You said that you
aren't racing or anything, just get new discs from the local parts store.
They will have two or three different discs to choose from, based on price.
My theory is that the mid-priced or high-priced parts will have a better
warranty than the cheap parts.
