How do i get the parking break unstuck at the driveshaft?

To unstick a parking brake that is stuck at the driveshaft, start by ensuring the vehicle is safely in neutral and on a flat surface. You can try gently rocking the vehicle back and forth while simultaneously pulling the parking brake lever or pressing the pedal to release tension. If that doesn't work, inspect the parking brake components for rust or debris and consider applying some penetrating oil. If the problem persists, consulting a professional mechanic may be necessary.
