Warped OEM rotors after 6k miles
We all know how lame the front rotors are, but I didnt realize they were this pathetic. Mine were dealer installed, 6k miles ago, then just replaced again under warranty because of severe warping. I know re torquing is important, but does anything else cause this?
The rims are factory chrome 16"

[QUOTE=Oldblue;799541]Those rear brake shoes must be adjusted every oil change , it's not a hard job.[QUOTE]
If I didn't know better I'd say this is beginning to sound like tryin' to maintain an ol' air-cooled V-dub!
But as I recall you had to adjust all four wheels back then...
And if you ever had to slam on the 'brakes' and one of those old rubber lines ballooned out you didn't know which ditch you might end up in.

Not trying to start an argument but rotors rarely, if ever, warp.
Typically what you see is uneven wear and pad transference. Both of these are usually caused by hard stops and high temperatures. After hard(panic) or prolonged(traffic) braking you need to drive for at least 5 minutes to let them cool. A car used for commuting in city traffic will rarely get 5 minutes of cool down time so rotors will need to be changed more often. Driven rural, 2-3 pad changes and rotors may still be true as measured by a dual indicator. My HHR that is driven hard gets rotors every 20k. My Suburban is at 100k on the original pads and rotors. My old road race truck got new rotors every 2-3 track days and more often when the temps were low as they would crack from the extreme temperature changes. My new 16" rotors on my pro-touring car are $400 each so I'll be cooling those down on track days very carefully.
