Uneven Brake Pad Wear

[adam.cantab]

Hi All,

Had a great time at Cadwell park on Friday. Though as the track dried I noticed a significant discrepancy in the wear on my front brake pads. The passenger side was wearing about twice as fast as the driver side. So a question to the more experienced and more mechanically minded. Has anyone else experienced this and if so what would typically be causing it? Worn discs perhaps?

Thanks,
Adam
