Rear brakes have been making a funny noise for past couple of days, like a grinding noise. Checked them today when i got to work and the rear drivers pad looked like it was hanging out the caliper, ie, you could see half the pad hanging lower then the caliper. Just checked it now i am home and the rear pad has gone, there are tiny metal flakes on the caliper, so its metal on metal

How could a pad work itself loose?! lol, time to get it into a garage for a service and a new pad, leeking oil from somewhere to (the engine that is, not the brakes lol)
