Brakes lockup on intial use during cold slow start

[tiredeli]

I have a 3.8 and love it. It seems to have developed an issue over the last couple of months. When getting into a cold (outside temp below 25f) car, pulling forward under 5 mph and then applying brakes, the brakes seem to "grab" or lockup the first few times. This issue quickly goes away as I continue to drive the car and warmup normally. Brought it in to the local dealer and the serviced the sliders, however the issue seems to persist. I am curious if anyone else has experienced this?

Same here on my 4.6... Very harsh stop at first. Weird.
