2006 Pontiac G6 Question: How often should I have to replace rotors?
Answer #1pushrod September 24, 2012, 09:25Master
WHY ARE YOU REPLACING SO MANY ROTORS? ARE THEY WORN OUT, WARPED OR WHAT?
ARE YOU A MAIL CARRIER, OR USE THE BRAKES A LOT? GIVE MORE BACKGROUND!

They just rust out (warp too) and grind. Actually I should correct that: one of the 3 times, two front ones were only turned (ground/renewed), but twice were complete replacements. The second replacement I managed to get the rotors warrantied, as it was just under a year. (During that year, I only put 7500 miles on the car.)

WHERE ARE THE ROTORS COMMING FROM?
WHAT PARTS STORE? FOR INSTANCE I HAVE A CHEVY. BLAZER WITH OVER 100 K MILES AND ONLY MACHINED ROTORS ONCE. DOES THE REPAIR SHOP SAY WHY YOU ARE HAVING THIS MUCH TROYBLE?

They just say they "came from China" (seriously). I don't know the brand, but parts were purchased from an auto supply store near East Aurora, NY (east of Buffalo).
