"warped" brake disks saga
 

a couple of months ago, i yet again encountered the bogey about warped
honda disks - and proved it to be simply fixed.

had taken my civic in to have the tires rebalanced. driving home, the
disks were "warped" and shuddering like crazy. didn't have time to deal
with it right away, but a few weeks later, took the wheels off,
re-torqued them, and while better, they still weren't perfect. i
wondered if they'd not permanently been damaged with that period of use
- they're only cheapo aftermarket disks. but i took the wheels off
again, cleaned up the hub areas, replaced, etc. this time, a little
better still, but again not perfect. finally, just to be pedantic, i
reassembled having scraped off all corrosion from the mating surface
inside the wheels as well as the disk and hub, then put antiseize on
that inside wheel surface. replaced the wheels, torqued properly -
disks smooth as silk!!!

moral of the story: while i don't recommend indiscriminate use of it, a
little antiseize between the wheel and disk hub surfaces appears to work
wonders and may save you an expensive disk skimming or replacing
exercise. make sure all corrosion is scraped off first.
