I have a 2004 4x2 Trailblazer LS with 220k miles well maintained. One of the calipers were leaking so I decided to change all of them since they were never changed. I changed all four calipers and now my gas gauge always reads empty and the ABS light stays on. They were working perfectly fine hours before. What gives? Could the new calipers have broken the ABS module? Is this like a security feature?
