There's three things to check. First check the left rear or the right front to see if brake fluid will flow from the bleeder screws. If not, the master cylinder must be reset. Only the right rear and left front are working. Next, remove the right rear drum again and check if the shoes are touching the anchor pin on top. If they are not, the parking brake cable is sticking and the shoes are partially applied. That will cause very easy wheel lockup. If the shoes are both touching the anchor pin, use your thumb to push the parking brake strut rod against the anti-rattle spring. It should move a good 1/16" to 1/8". If it won't move it is holding pressure on the shoes, again, from the parking brake cable sticking or it is over-adjusted. If the cable is fully retracted by prying the parking brake lever back, and you still can't move the strut rod, remove the anti-rattle spring and try it again. There was a problem with that spring being too fat and causing easy rear wheel lockup, but that goes way back to the early '80s. The only way that would happen today is if the wrong spring was installed recently.
