I have an 07 Civic LX...recently after the car has been parked overnight and when I start driving in the AM or even PM the front driver side wheel starts to whine or squeal when I drive...when I apply the brakes it gets softer but getting up to speed it gets louder...eventually after it will stop for a few miles and then start up again...I took the tire off inspected the pads, calipers, disc and all looks good...the tired does not shake or rattle like it would with a wheel baring that is going bad. I am stumped and don't know what to make of the noise...any ideas would be very helpful.
Thanks

Raise it up and spin the wheels, see if the noise is present so you can hunt for it?

Rocks, splash shield/backing plate, brake pad shims and clips, etc....

Did you actually remove the inboard brake pad to see if the pad thickness was near the squeal indicator? If you just take a glance, it can look passable.

My 2008 Honda Fit had a similar problem. I thought my tire was going flat on the highway, but all 4 were fine. Car had over 100k miles. Turns out to be a stuck caliper. Brake was humming and rumbling. Worse as rotor got hot. I had my brake fluid flushed out (first time) and all linkages and moving parts cleaned and properly lubed. Problem all gone! The car stops better than when it was new.
