A brake retarder valve (10) for a tractor-trailer combination comprises a valve housing (12) and a valve assembly. The valve assembly includes a poppet valve (26) biased by a spring (24) and a gravity spool. The valve assembly is selectively operable between the operative closed configuration and an open configuration in response to a resultant of the fluid pressure between a trailer axle brake (13b) and a tractor axle brake (13a). The tractor axle brake (13a) is actuated with a time delay from actuation of the trailer axle brake (13b). This delay is actuation of the tractor axle brake (13a) prevents jack knifing of the trailer onto the tractor in a tractor-trailer combination, thereby ensuring safety during operation of a tractor-trailer combination.
