1994 C4 park brake broken
I have a 1994 Competition Yellow/Black convertible top C4. My park brake cable broke at the handle inside the car by the driver's seat. The brakes are locked and I cannot reset the brake to drive the car. Is there a way to manually release the parking brake? Is there an aftermarket brake handle available to replace the GM one?
Thank you,
Ken Adams, Jr.

I'm a little confused when the cable brakes it releases the tension, not to be rude do you understand the brake lever operation.
The later system require a pull up to tension the cable and release tension from the Pall before the button will allow the release and cage of the latch, allowing the cable to release.
But if you're latch is truly broken (which happens) you can remove the Left Rear wheel find the Tensioner/slack adjuster and back it off

I do understand the brake lever operation, the cable that runs to the brakes isn't the cable that broke. The "cable" that broke is the one that appears to be a copper-colored flat piece located inside the car and is connected to the handle. I cannot disengage the brake with the handle at this time. I will remove the left rear tire, locate the tensioner/slack adjuster and back it off. Thank you.

In the end it sounds like the ratchet is the problem, sounds like the cam release isn't working. So once you get the car rolling again and tension off of things hit up You Tube to see how to cage the parking brake tensioner cam.
If possible see if you can get it freed up caged, then adjust up the cable you loosened.
A lot of people don't know about the caging of the handle at brake job time, what happens owner #1 drives a factory car. Sells to owner #2 who feels great and sez the car has 50,000 let's do a brake job. He pulls things the ratchet already has adjusted some or has maxed out from the disability. So owner #2 does what you did to get moving just to put the Pads back in.
So in short you need to reset the Adjustment cam and the cable, and if nothing is broken you should get away with some skinned knuckles and Fowl words

I believe that this is the problem, "sounds like the ratchet is the problem, sounds like the cam release isn't working" and I will do as you said to see if I can get this to release. I am owner #3 of this car and it only has 82k miles on it. The brakes still stop me very well but will check them out also.
Thank you,
