I was looking up the parts for the rear brakes on the chevy timhis morning. There was way too many choices for rear rotors pads and calipers. 325 or 330 mm rotors? Like 3 different calipers,thats 6 for some shop to stock. And then the brake pads,metallic,ceramic,semi metallic, organic and i thought i saw high carbon or something. The amount of space all these parts take is enormous. Again, wtf were they thinking?
