Brake Noise in Cold Weather

[BenScott]

Morning all,

My 2000 LC has been making an odd pulsating, click/thumping sound when I'm at a stop and only does this when it's very cold outside. Could it be related to the booster or something? The brakes themselves feel and perform fine but the noise would seem to me that something needs to be addressed. Any thoughts where the issue might be?

Thanks,
Ben

How cold is cold? Once the vehicle warms up does it still do it?

I would say it typically happens when the temperature is < 30 degrees. The noise goes away after the truck has warmed up.
