Hi all. I have a 2000 Mustang GT that has failed inspection twice due to the parking brake. Two comments were made by the DMV guy. 1) Failure to stop vehicle and 2) Not enough reserve. I dont know what this means but I have had the following repaired since then and it still wont pass inspection. I have replaced both rear calipers, brake pads, rotors, e-brake cables. I am running out of things to replace. Anyone have any ideas what to check next? I need to get through inspection by the end of January. Thanks!
