Clutch pedal 'gritty'

[epapp]

Hi guys, long time lurker, and potential buyer. I went to drive one today and it was all ok except for a gritty feeling when pushing the clutch in. It clicks lightly probably 9-10 times throughout a depression of the pedal, and again upon releasing the pedal. It almost feels like its a gummed up cable that the pedal is pulling. I'm new to the boxster so I don't know enough about what it could be. Any ideas? Is it the master cylinder failing or just something that needs to be lubed? When the pedal is actuating, the sound is pronounced at the pedal location and at the clutch fork area.

Thanks
