Rotors are warped. A while back there was a lot of discussion regards
to what extenet they are warped and to what extent the problem is
thickness variation. Who cares? The rotors are not flat and true
causing brake pulsation. You can get them turned and the problem
will come back. Sooner if the rotors are really bad and are of
inconsisent metallurgy due to uneven heat treatment from the uneven
braking, sooner if they are already thin, sooner if the brake lathe is
poorly maintained, sooner if the lugnuts are tightened unevenly many
people claim, sooner if you use the hell out of the brakes and often
get them hot. New rotors from a quality source will hold the problem
at bay for a long time -- again dependent on driving habits.

They won't fail directly because of the pulsation. Its reasonable to
presume steering and suspension components wear faster, however.

About $200 if you do it yourself and use really good rotors such as
"Mountain" brand or original equipment Honda. $3-400 if you have it
done depending on whether pads are replaced at the same time.

Brake pulsation should not be a deal-breaker. If you set up a road
block on your street and checked the next 20 cars to come by probably
half or more would have some degree of brake pulsation.

Don, I for one think you covered all the discussions I've read on this
forum re: disc brake rotor pulsations. I fully agree that it is just a
matter of time which can be hurried depending on the many factors you
pointed out. No permanent solution! s
