My front left tire has been making a squealing noise. Now this noise isnt when the brakes are applied with normal stoping force just when driving and slight brake pressure. Its not a constant noise its kind of like, squeal, squeal, squeal and get a faster as i go. Any ideas?

 

My wifes car was just doing the same thing and the tire was losing air. It was a leaking where you put the air in. Can't think of the name of that damn piece.

 

valve stem

could be the little metal clip thats on the brake pads to let you know they need to be replaced soon....if you only hear it once and a while then it might not be completely worn down but they are on their way there

 

had a bud who changed out pads, rotor, and wheel bearing. turned out to be the dust shield rubbing the rotor. something to check before the pads, good luck.

 

my wifes jeep had that dust shield problem....i just reached under there with a pair of pliers and bent it back....solved the problem
