Hello Pocacosa, that problem is revealed to the handbrake comb, its teeth after a while they are recent and weed and they no longer perform the lock, it is unlikely that it is your piola since generally when it is cut it shows in the teencion of the handbrake, that is to say it does not put resistance when throwing it, if that is your case is the piola, but, it is only the comb. Try to throw it up and then carry it towards the right or the left see if it works this is as you see how to change it, not for a hundred it only works little time.
