Well time to schedule an appointment. Car has 26,000 miles. Original tires and brakes.

Front driver side wheel or tire or brake is squealing.

Basically it is as the wheel turns, there is a spot that squeals. Sounds like a grinding squeal. It changes tempo as I go faster or slower. Does not stop when I apply the brakes. Can only be heard if I am driving next to another car/wall/anything to reflect the sound back at me. This is in addition to a small brake squeal when applying brakes.

My guess is a worn rotor, slightly warped, whose lip is hitting something on the brake pad.

Any guesses as to what could cause a consistent, yet not continous squeal noise from a wheel region?

 

Sounds like the low pad indicator. Time for new brakes!

 

But wouldnt the low pad indicator squal all the time then, and not just on and off?

 

Could be from slamming on the brakes at some point on the rotor, so that it's only that section of the rotor. Mine squeals only sometimes when I back up.
