Engine cold. trans. in either reverse or drive. upon releasing brake car moves too fast. when applying brake nothing happens. after repeatedly applying brake they finally catch has happened at least 5 times. this time they didn't catch and i rearended a pickup waiting at a stop sign. i don't think i failed to apply the brakes properly because i raised my foot off the brake and reapplied them at least twice before impact but that is never-the-less still a possibility. *tr
