S5 creaking calliper

[SI-W85]

I have just upgraded (i hope) to some S5 callipers and black diamond discs with some EBC red stuff pads. Anyway they were fitted to my A4 last Saturday I then drove 300 miles to the Isle of Wight and upon arrival shortly after I noticed a horrible creaking noise coming from the front drivers brake, the noise sounds to be coming from the calliper, all sliders are greased ect ect so I am wondering if anybody has experienced this noise with there brakes before. I have a short YouTube vid for you to hear. S5 creaky calliper - YouTube

Also I will add it does it when stood still by pressing the pedal on and off :/ I had the calliper in bits last night and checked everything but could not find where the noise could be coming from. It's driving me mad already

Did you copper grease the back of the pads

I did use copper grease even though most say not I I still do it :/ I have been told to get some ceramic grease and do the sliders.

I had the same problem with the OEM callipers and Audi fixed it last week.
It turned out to be corrosion in the brake pads holder

Interesting :/ although I have stripped them down and there doesn't seem to be any corrosion but will double check when I next get the time to take in bits again.
