Brakes packed

You have a good day, I have a small problem (big) I have the brake problem of a Toyota Corolla Model 92, which changed rear shoes since the ones they had were well worn out, I changed them but I gave a couple of turns and I struck me I thought it was because they were thick they wear them but the problem persists, when the pressure is removed through the faucets. Someone can help me, I thank you because I sincerely ended my ideas thanks for your attention and for your help.

I do not remember if the corolla is of disk or drum drum You should check first the brake line seeing if the cylinder returns when you stop stopping the other it is ke the cylidro has oxide that prevents the cylinder from its return and it is cool They are well and if possible, see the cylinders taking away a rubber tries a pruba without a drum supporting you with two screams oppressing the shoes and that a person helps you to cool to see all the function of the brakes
