I put new OEM reman calipers, DBA rotors, and non-OEM semi-metallic 100 series pads on about 5000 miles ago. After a few thousand miles I started to get brake pedal pulsations pretty bad. Pulled out the pads on the DS tonight and found uneven wear on the outside edge of the outboard pad and rotor. The strip of decreased wear/contact on the rotor only goes about half way around the outer edge of rotor. The inboard surface of the rotor and that pad are wearing evenly. Here are some photos: First photo shows the decreased contact area of the rotor, notice how it stops abruptly. Second is a close up of that area, the irregular surface was a tad rusty from not being wiped off by the pad. Third shows how the outside edge of the pad is not wearing at the same rate as the rest of the pad. Anyone else see this when using 100 series pads?
