Abstract
A braking system having a disk brake that is mechanically connected to at least one wheel of the vehicle and cooperates with a brake caliper that is actuated by a threaded rod screwed through a threaded connection in a control nut rotatively mounted inside the caliper body, the threaded connection being irreversible by axial forces alone. The brake linings are made of an elastomeric material having a high friction coefficient when the disk is not rotating. This system provides a compact parking brake having a high power and a large remote-indication capacity, and is particularly useful in railroad vehicles.
