The other day when i went to brake i heard a really loud squeaking noise come from the driver side rear brake, when i got home i took off the wheel to look and the brake had been completely worn to nothing. I changed out the brake pad and checked my other breaks but they were still almost as new for i had only changed them four months ago.

After i drove the car for a little while i stopped to look at the brake and could smell that it had been rubbing. The brake pad seems to rub the rotor while driving, but it doesn't affect the driving, the car doesn't pull or anything. Does anyone know how to adjust the calipur so that the brake pad doesn't rub the rotor? It is only this one brake that is rubbing and I know that i changed the brake pads properly so please don't say that i don't know how to change brake pads.

Thanks for any help!
