I just put some Akebono pads on my 2001 Aero. The new pads now have 500 miles on them so they should be bed in. I just noticed that on the rears only half of the rotor surface is cvlean and the other half is rusted as though only half of the pad is providing braking. You can see in this first picture. I don't know why this is this way. Could something be wrong? I took a pic from the back side of the caliper. On the second pic you can see how on the tangs on the pads that only the inside pad tang is over the recessed area of the caliper and the outside pad the tang is outside of the recessed area of the caliper. Is this correct?
