High-pitched noise when NOT braking

Hello all.

I have a high pitched noise coming from my right rear of my 2001 Honda
Accord V6. The noise is medium intensity and sounds like a squeal, kind
of like the sound your CD player makes when it is skipping. It is a
very shrill noise. I have disc brakes in the back by the way. This
noise comes and goes while driving, and changes in pitch and intensity
when I brake. The noise also only happens when I'm moving; otherwise,
it is completely random. I checked my outer brake pad and it looks
fine--the rotor is smooth on both sides. I didn't check the inner brake
pad so I don't know if it is worn, but I would imagine that if it were
worn, it would make a noise WHEN I braked, not the other way around.
What is this noise? Thanks for your help,

Josh

Check the inner pads. They're the ones with the squeal tab.

Noises *can* occur when not braking and disappear once the pedal is
touched.

Check the owner's manual description... I'm sure it is like you
describe.

Yeah, I too, have what I'd call a tracing rotational metal scrape even
on good brakes. Normally silenced by applying the brakes. Often
silenced by turning hard in one particular direction. What do you
suspect? Pad clips? Or more likely binding/drying caliper pins?

Not sure. Possibly pretty much any one or combination of the sliding
parts are binding.

It can also occur simply because the squeal tab is just beginning to
make contact with the disc. When the hub/brake assembly deforms slightly
under braking and steering stresses, the squeal tab barely makes
contact. Whe you squeeze the pads on to the disc by stepping on the
pedal, you force everything back into proper alignment and the tab is
lifted off the disc.

Either way, eventually the squeal will happen regularly and the pads will
need to be replaced.

 

NOT "braking and steering", JUST "steering". Brain fart while I was
typing the earlier message.
