I was gearing myself up for my 1st crack at changing the front brake pads, pulled one wheel off to have a look before starting on the weekend and noticed the inner brake pad on the frivers side is worn about 3mm more on one end than the other. And the worn end has gone right through the pad and was grinding the metal backing against the rotor, gouging the rotor in the process(Good excuse to get slotted rotors now though

).
I'd like to take a pic to help explain but my camera has packed it in.
Does this happen usually? I thought the brakes were supposed to squeal a bit when they were getting low? There is only about 1mm or so of pad left on the outer pad, thats what made me think of changing them. Seems strange to me... What do you guys think?
