With the rear wheels jacked up off of the ground, apply the emg. brake ONE notch at a atim and ck to see if each wheel is starting to hold when you turn them each by hand. You may have a broken E. brake cable. Also, you can adjust the E. brake shoes up just like older car brakes. They have a star adjuster just like old VWs. You need to pull the wheel off and adjust through the hole in the rotor.
