It's likely that they just need using a little, they make all sorts of wierd noises at times.

2 things though, it's important that there are no grinding noises, this will f### the discs in no time. (as the metal pad backing rubs on the discs)

It's important that the brakes are not dragging, this will warp the discs in a slightly longer time. (through overheating)


It's likely a brake strip and rebuild will help matters like, but if it only does it when cold then I would just bear it in mind for the minute and check it doesn't get worse, especially if they drag.
