E-brake is extremely hard to pull

i wanted my e brake to work properly i can push my car when it is applied.... i can only get 1 click when i pull up on my e-brake the pads are like new, yesterday i tried to give it a second click and it will not budge..... took both e-brake cables off of the e brake mechanism on the calipers took vise-grips and i can get like a 1/4 and that's it on both sides if i pull one side the other side gets tight.... i had to take pb blaster to free up the mechanisms on the calipers and they move freely now, also 2 sliding pins were locked up so idk if that has anything to do with it or not ? just seems like the cable is too short i have tried to find videos on how to adjust the cable but i cannot find anything...

if anyone has ideas,thoughts,advice please let me know

It works properly when released but all I can get out of it is two clicks it will not hold on any type of incline

i tried to use my calipers and put the brakes back together and they locked up.... so i put the new calipers on, and bled them out and the brakes work ! i also figured out how to adjust the e-brake this is why i only had a 1/4 inch of play, after i did that i had all kinds of cable but only one side is grabbing i have tried putting it in reverse and then go to neutral and pulling the e brake im not sure how the self adjusting mechanism works.... i will try to bleed some more with the car running and see what happens
