Mine is doing this aswell, But both fronts. Like you only when cold or a bit warm and at low speed. Never did it with the first set of M1144's I had with XDG maxtorq disks. But its doing it loads with the M1144's and XDG black diamond disks. I am using the rubber backing stickers but no copper slip as I find it just atracts dirt.
What disks are you using?
Could just be this batch of pads.

Mine have been fitted for 3 months approx.
