parking brake stuck on 1995 Pontiac Bonneville

The step on to engage, step on to release style brake has been giving trouble lately. It works fine engaging but does not release without a struggle. Depressing the pedal ever and ever harder. Last night I just could not get it to release. The tow truck driver said he could see the emergency release tab but couldn't get it to let go. What can I do?

You'll need to have it diagnosed, there are several possibilities but an inspection and a few tests should pinpoint the problem. What you can do is make sure the brake lights are working, they often use the signal from the brake light switch to activate the shift lock.
