Are there any known issues with CRV rotors warping or similar
pad/rotor pulsation problems and premature wear ?

Friend has a 2005 with only 20K miles on it. Rears are not looking so
good and there is a slight pulsation problem. I know it could be
"normal" but I'm wondering if it's common and something the dealers
are fixing.

Thanks,

If they are wearing worse on one side than the other, the sliders are
not properly lubed (from new).

Sign in search. Lots of good stuff already covered.

Tegger.com also has good materials about this problem.

it's almost certainly due to incorrect wheel torque procedure when the
tires are rotated. it's a common problem. wheels need to be tightened
in a two-stage process using the correct bolt sequence. do NOT allow
air tools to be used.

It is almost an urban legend now to blame all brake rotor vibration
problems on mis-torquing. In fact, Honda changed pad materials on some
2003 models and issued a service bulletin to address these problems.
Many other makers have had this issue from time to time as well.

Contrary to popular opinion, the trouble is often that the brake rotor
has developed a thickness variation rather than simply warping like a
potato chip.

well, my experience is that i brought a civic home from a brake
inspection with rotors that were so warped, it was ridiculous. i drove
it there, brakes were fine, drove it home, brakes were pigs. re-torqued
the wheels as described, brakes were fine again. /that/ is not a
thickness variation.

I stopped having trouble with brake pulsation when I started using a torque
wrench on wheel lugs. Of course, that doesn't mean *all* pulsation comes
from overtorquing.

I think I'm changing my mind about 'warping'. I read this (long) article
the other day that seems to confirm what you're saying, John. It also
explains how you could 'drive home' and have (apparently) warped rotors
when you got there . . .

Improper torquing can indeed cause this problem, my only point is that
not all brake problems are due to poor wheel tightening procedures.

I'm very familiar with this information and have first hand experience
with the deposit issues. I also know about torque issues.

But my question really was whether or not CRV's suffer from a known
issue/defect in this area (lots of them have brake problems such as
this) or it's a mechanical issue specific to this car.

Thanks,
