MMC Disk and Pads

[Stig95]

Just got home tonight to the sound of my mmc's making what can only be described as a high pitched squeak. After doing my usual Friday night check oil, header tank etc etc. I noticed what appears to be a stone grooved carved into my mmc disk on the front drivers side.

With the being alloy aluminium I am more than a little worried by this. I will try and get a pic later however from what I can tell the "grove" is at most 2 mm deep.

Does the score mean I need new pads and disk on the front of the car or all round? If so what are my options? As i assume i cannot have normal disk on the front and mmc on the rear etc.

Thanks in advance
