Car noise squel

When i first start my car and start moving i hear a squel/horn noise (not really loud like a belt slipping) . When the brakes are applied the noise stops. after 2 minutes it stops and doesn’t do it for several hours, possibly until the car is cooled down. I happens on and off and my mechanic didn’t hear it. Any ideas? Bearings, belts etc…

it is a 2001 honda accord with 96k miles.

From afar, my best guess is that you are hearing the brake wear indicators, which are supposed to sound–more or less–like a cricket chirping. This noise normally goes away when the brakes are applied.

I would suggest that you have the pads on all 4 wheels checked before you wind up ruining your rotors.
