Brake Pads

I've been wanting to replace the brake pads on the back wheel of my bike for quite a while now, but never got round to it. Had to replace the front pads a while back and did that almost immediately since I couldn't brake properly any more (you can see the old ones in the photo along with the new ones for the back wheel)
Will eventually do it... preferably before I hit a wall.

Second revision lecture today, went straight home after it and spend the day doing revision until I lost motivation at around half nine...

Am currently listening to my complete music library again and sorting out music of dubious origin...
