I guess I stand corrected! Maybe, or maybe not? I'm sorry if maybe I didn't
word my opinion correctly and made it sound like rotors "always" need to be
turned. If you have ever seen the rotors I've had to deal with I'm sure you
would agree with me. The DM may work well when people "take care" of their
cars, and are compliant to the needs of said vehicle, but when you tell
someone they need their brakes done and they show up two months later and ok
the job..... !! By then the damage is done, nice grooves, gouges or whatever
you might want to call them, in a nutshell its neglect. " I didn't have the
money to do it then" . Well I'm sorry but it will cost you MORE now, a price
has to be paid! A little now or MORE later, took me 16 years to get this
through my wifes head. (on her car of course!)  I like the idea of
"scheduled maintainance" and I've always believed that the term "preventive
maint." is a crock, you never prevent the inevitable from happening , you
merely prolong it! i.e. I change my oil every 3k, does that mean my engine
will live forever? not hardly , but it will live longer! It will eventually
need bearings and rings etc.! just my .02 ! :~)
