Mid-Year Parking Brake
Doug,
Sounds like a great car. Thanks for the compliment. I don't want to get off track with the original intent of this thread but I'm sure the other folks won't mind too much if I share some basic information with you. Just remember that, back then, these things were called "Parking Brakes", and probably for good reason, as I don't know how well they would work in a real emergency!
I can help give you a general overview of the emergency brake but it would be a good idea to either get a copy of a 67 Service Manual (which outlines the proceedure) or take the car to someone who has done this job before depending on how much of this job you want to do yourself.
I guess the first thing I would do is check to make sure that the adjustment on the cable and the brake shoes is adjusted properly. The mid-years have internal drum emergency brake shoes within the disk brake rotor. Over time they can wear and need some take-up.
If that doesn't do it you will have to get to the brake shoes themselves. That might involve drilling out the rivets that hold rotor as it is riveted to the spindle. If someone has already done this job in the past they would already be drilled and you could avoid that step. Check the cable to make sure it moves freely as it could be bound. If that's okay, check the shoe linings and adjustment. If the shoes are in good shape it might just need some adjustment or careful lubrication of the backing plate pads and threads on the adjustment screws. If not, you might want to replace the shoes and springs. Kits are available from the various Corvette vendors.
Hope that helps give you a general idea of what's involved but I'd be sure to get a Service Manual as it will be useful for this job as well as many others.
