Got a question concerning the rear brake pads on my 2000 trans am ws6 vert. Does anyone have the same rear pads as mine and know where to find new replacements my pads have the butterfly springs on the bottom of the pad that compresses and locks the pad into place. Been needing to replace them but can't find any pads like them. Anybody know where I can find them or tell me any info or is my cars pads an odd ball or something.. Help please. Thanks.
