Metal grinding sound when breaking (car is cold)

[Anton CH.]

I started to notice that when the car is cold and I am brake, there is a metal grinding sound coming from the front left wheel. Is this something to be concerned about?

The sound goes away once the car is warm.

....one of those 'do it yourself' car washes, and thoroughly spray out your brakes rotors, calipers and the inside of your wheel. Sometimes even a build up of brake dust can cause various squeaks and squeals. If it still persists, I'd pull your that wheel, to check out both the pads and rotor for wear. If they're worn, I'd also check out the condition of your rear brakes, too, then plan to do a brake job involving at least the front end.

Hope that helps,
