Railway braking system for a rail vehicle and method for assembling and/or disassembling a railway braking system

A method for assembling and/or disassembling a railway braking system for a rail vehicle with brakes with at least one lining, configured to act on at least one rotary braking member of the rail vehicle via the at least one lining and including a braking unit provided with a brake rigging having the at least one lining and a brake cylinder configured to actuate the brake rigging, the braking unit extending in a longitudinal general direction generally orthogonal to an axis of rotation of the at least one rotary braking member, and a fixing interface secured to the braking unit and configured to be fixed onto a support of the rail vehicle in an assembly direction generally perpendicular to the longitudinal general direction and to the axis of rotation, characterised in that the fixing interface is provided with a mounting block configured to be mounted by nesting with the support of the vehicle in the assembly direction and having at least one bearing face, and members for fixing the at least one bearing face which extend in a direction distinct from the assembly direction, the method comprising nesting and/or disengaging the mounting block of the fixing interface with the support of the vehicle in the assembly direction, and mechanically securing the mounting block in a direction distinct from the assembly direction by the at least one bearing face and by the members for fixing the at least one bearing face.
