Does anybody know any causes? Can bad brake caliper assemblies cause this sort of thing?
Very frustrating. I have to replace my rotors this month as my hand shakes violently on the wheel when I apply the brakes at high speed.
That's odd. I have 145k on the original rotors on my '96 SL2 and only recently did they start develop a pedal pulsation. If you are having issues with depositing uneven pad material, it may be because you are overheating the pads? Have you considered installing a set of pads such as Hawk HPS, which are more high-temperature friendly? Since the part number for S-Series cars is being discontinued, I purchase a set of Hawk HPS pads for my SL2 for $20 shipped. Also, make sure you are cleaning the hub flange during rotor installation as well using a torque wrench to install lug nuts.
