In a 1996 mustang gt, my brother pulled to hard on his e brake and it doesn't brake anymore, it's still attached but doesn't click to perform the brake. It's a 5 speed. Anyone with an sn95 know the resolution?
I'd look underneathe and follow the E-brake cable to the rear end. See if he snapped/broke it. Maybe it came off the clips on the rear axle? that is where I would start if it is not working at all he may need to find out if that is the issue and replace if broken.
