Escort 97 handbrake problem

Hello everyone, I have problems with the hand brake of a Ford Escort Model 97, it has a four -wheel disc brake, the problem is that when changing the rear pads the handbrake no longer worked (it is no longer activated) I had already spent it, and after much activate the hand brake lever, it was beginning to grab again, but as I can do so that the problem does not happen again in another change in another change in another change in another change

I think that when the pills change you do not put the cable on the gag.
