[Biturbos4] Sound from front breaks

[Aurangzeb M. Agha]

I've been away on vacation for 10 days and came back to my car this 
morning.  After driving on the highway for about 45 minutes, when I got 
closer to my home, I started using my breaks and noticed that I was 
getting a sound whenever I hit the breaks which went something like:

	dhud-dhud-dhud-dhud-dhud-dhud

Any idea what this might be?  It's been very cold over the past few days, 
so could it be ice build-up?  If so, I would have thought this would have 
dissapeared with a few strong, hard breaks.

Any thoughts?


Rgs,

Zeb
