Naz24 – Sorry for the delay in response.
I should mention I didn’t adjust the rear shoes, I adjusted the cables. So, here you go:

1- Pull the e-brake cover off the handle
2- Loosen the two bolts that hold the two cables (right & left wheel brake)
3- Tighten the two bolts in parallel
4- Raise the driver side rear wheel
5- Check to make sure that the real wheel spins freely. If not, loosen the bolt a tad and check again. Operate the e-brake few times
6- Lower the driver side and raise the passenger side
7- Repeat step 5
8- Lower the car.
9- Engage the e-brake, start the engine, shift to D and see if your car moves. I got mine to the point that even moderate push on the gas can’t move the car.
10- Put the e-brake down. Drive around the block.
11- Raise each side and make sure both rear wheels spins freely with no frictions.
12- You are done.
It took me about 45mins.

Good luck
