I just became the owner of a 1928 Model A coupe that has been sitting in a garage for about 15 years, and am in the process of trying to get it running. When we pushed it into my garage, I set the emergency brake. Now that I am ready to roll it outside and try to get it running, the release button won't push, and the brake won't release. Any ideas on what I should do to get it to release? Any help will be appreciated.
