Hand brake (pedal) Chevbrolet Colorado year 2004

I would like to know how the handbrake (which is pedal) is regulated in the Colorado Chevrolet year 2004, because I have one and I don't know how I can regulate it or I just have to change the rear tiles or brakes, from before hands thank you.

Surely brings the regulation below the vehicle

The easiest friend is segiring the piola from the avitaculo to the trains trains in one of its parts would have to have a regulator, they are usually below the vehicle in cars of those years and especially when they are pedal, but there is also the possibility that it does not bring and regulate from the traceras tales.
