I have a 1965 full-size Buick with front and rear drum brakes which has been in storage for several years. I never used the parking brake even when I used it as a daily driver so it's been engaged maybe twice since 1991.
I've moved from a non-inspection state (Illinois) to an inspection state (Delaware) and intend to have the car shipped out and re-registered/titled in my new location.
Per the guidelines on the Delaware DMV Website my car is old enough that it is exempt from the emissions and fuel pressure tests but there is mention of a brake test. When I have tested my newer vehicles (2005+) this has been as straightforward as stopping the car when/where the tech tells me to but given how much the testing seems to vary based on vehicle age the requirements in practice may be different. I would hate to be asked to apply the parking brake and have it catch but not release.
Even without implications from the inspection, it would be good to know that the parking brake does, in fact, work.
With that in mind, I have some questions.
- What can I look for before I even try applying the parking brake? Are there parts I should lubricate, or indicators that I should pull the drums right away?
- Is there a good initial way to test the effectiveness of the parking brake other than putting the car in neutral and giving it a push?
- Is it possible for the parking brake to engage and not release? If this happens, what can I do to get it unstuck?
I have some experience wrenching on the car and generally enjoy it (I swapped the single master cylinder with a dual and replaced the brake lines and replaced the heater core) so I'd like to do the work myself if I can.
