Abstract
Disclosed is a brake system for a railroad vehicle, including a parking brake provided with a piston and having a first configuration in which the piston is in a working position in which it acts on a lining support and applies a predetermined force to a brake disc; a second configuration in which the piston is in a rest position in which it does not act on the support and does not apply any force to the disc; and a third configuration in which, when the vehicle is not at a standstill and the ambient temperature in the environment of the disc is greater than a threshold value, it forces the piston to move towards a trip position different from its working and rest positions, in order to limit or cancel the force applied to the disc.
