Beschreibung
Zusammenfassung:	Hydraulic brake arrangement (1) for a tractor or a tractor-trailer combination, comprising: - a tractor brake module (4) provided with at least a master brake cylinder (6) configured to provide pressurized fluid to brakes (2a, 2b) of a tractor, - a trailer brake valve module (5) comprising a hydraulically actuated trailer brake valve (13) and an electro actuated proportional valve (14), - a coupling module (22) configured to allow the fluidic communication between the trailer brake valve module (5) and trailer's brakes (3), the coupling module (22) comprising a pair of couplers (23, 24), wherein the trailer brake valve (13) is controlled by a pair of hydraulic pilot signals (L1, L2) acting on one side of its spool, such signals being generated via an electronic unit electrically connected to pressure sensor means (33) and to switches (34) elaborating their retrieved data.
