Hey cdn2, welcome! There is a thread in the 4.3 Mechanical section which has a description for adjusting the cable at the handbrake lever, but this should only be in case of a stretched cable. There are a couple of things we should be clear on from your post though.
1. Your rear pads and rotors are not part of your ebrake system - the ebrake handle only operates the brake shoes inside the rear rotor/drum.
2. The primary adjustment for the brake shoes should be the star wheel spreader between the shoes (accessible through the port on the backing plate). Only once that has been set for each side should you consider the cable adjuster on the handle.
3. Which part are you referring to in saying “do not have any ... left?” I don’t quite understand.
We’re happy to help though!
