Save yourself the hassle of replacing the rotors and pads again in six
months or a year. If they look marginal replace them. Every one I have had
turned start pulsing within a year. They are cheap enough.
if you have ripples in the rotors then they need to be turned(machined)
and it they are worn too much then you need new ones.. autozone got them
for about $26-$35 each depending on what car they are for....
i would go for the rotors as most shops now charge $10 or more to turn
rotors...for a few bucks more you get new ones.....
The good cheap ones are usually made in Canada and sometimes even
Europe. Don't get cheap rotors from some thirld world country (i.e.-
I also never turn rotors. I can get new ones for my Escort for less
than $20 so I certainly wouldn't turn ones that already have over
100,000 miles on them. Rotors are a wearing part.
If you want maximum stopping power, you want a perfectly flat rotor surface
because of maximum pad to rotor contact. If you buy a new rotor, watch out
for the cheap Chinese aftermarkets, although I've tried them on a vehicle
with some success. When I was looking, the local auto parts store only
sold two, one made in China, the other made in Mexico. I personally can't
stand stuff made in either country, but that's another story.
My opinion, is that if you have the original equipment rotor, and it has
only minor wear, if you get it turned at the right place (they don't remove
more than is necessary), then turning it could be better than buying the
lesser grade Chinese version. Some shops will take off a large amount with
the rough cut, and then do a final cut. If done properly, there should only
be just enough taken off to give the rotor a good, true finish.
For whatever it's worth,
Will someone explain the reason for changing or turning the rotors other than
the book says to. I did once 20 years ago but only changed pads since. I have
probably accumulated 3/4 million miles on the family fleet (dads pays for and
fixes) until the kids are through college. Changing pads is not all that
difficult or costly to buy good pads. My most interesting story is the time my
daughter came home sat. night and said the car sounds like it is grinding every
time I use the brakes. I took it to church Sun. AM and it did. Bought a set of
pads on the way home. Installed them, burned them in and sent the Wife and
family on 500 mi trip early P.M. I run my main cars 140-180k.
You dont have to turn them unless they are warped or damaged in some other
way like hot spots or deep grooves. If you do turn them for no good reason
you are just taking off more of their thickness (and strength) making them
more susceptable to warping.

My Ford factory shop manual says NOT to turn rotors unless they are deeply
grooved. The directions sy to sand the rotors to remove the glaze, then
install new pads. I have a '95 CV with 4-wheel discs - it stops wonderfully
with the new pads and doesn't pulsate or make a sound...
Shops, especially the chains, seem to turn rotors take
make it less likely that a customer will come back in
just a few days saying that the brake pedal is pulsing.
And they care charge more for the brake job by utiling
the brake lathe to make $$$.
