I have a beautiful 66 Town Landau with 428 which is loaded to the gill with goodies. Had it about a year and have been working through the many things that need to be adjusted or replaced after 44 years. Lots of things don't work but one by one I am getting them functional. This Forum has been extremely useful and appreciate the members sharing their experience and expertise. This is my second Flair Bird with first being a 65 convertible back in 1970.
Finally getting time to track down the gremlins. First one is the parking brake. Has not worked since I bought the car. Prior owner disconnected both the vacuum inlet and the parking brake vacuum hose from the steering neutral safety switch. I reconnected them but it does not matter whether vacuum line is on top or on bottom port as the parking brake now releases as soon as vacuum comes up when motor is started. I was surprised that there were no electrical connections to the switch but learned while doing more research that C6 has it's own switch on tranny so the column switch is only for parking brake release. I do see contacts for electrical connector but no harness disconnected nearby (there is one connector for the cruise control which is disconnected).
Any suggestions why brake releases immediately rather than when shifter is moved to drive? Not sure how the switch is supposed to release parking brake when shifting into drive if there is no external event triggering it. Note that I checked the service manual and it only talks about how to replace the parking brake vacuum set up and not diagnose this tupe of problem. Thanks for any help in advance! John
