pull the shaft
If you look down just behind the emergency brake there is a little black plastic object maybe the size of a quarter you can push that and release the brake.
I don't know about Silverado trucks but all of the emergency (parking) brakes I'm familiar with use the brake cable to "pull" and hold the brake against the drum (or disk), so if the cable breaks you simply cannot apply the emergency brake. That is, it is automatically released if the the cable breaks.
Try to grab the release mechanism , where the handle was, with a vice grip or pliers. Push down slightly on the emergency brake pedal to relieve pressure on the locking mechanism. You should be able to pull the release out.
Pull the release handle for the e brake and then while its pulled out pull up on the pedal
The cable runs from the release under the dash to the adjustment bracket under the Silverado. Remove the nut at the adjustment bracket and disconnect the cable. Pull the cable at the dash end for some slack, and disconnect from the dash release. The cable can now be pulled out and replaced.
