Vehicle description: passenger vehicles not equipped with the anti-lock braking system (ABS). A pressure conscious reducing valve (pcrv) in the rear brakes may be subject to corrosion and result in malfunction, when operated in areas that use salt compounds on the roadway for de-icing or dust control.
Risk: If both pcrv's malfunction, vehicle handling could be adversely affected during braking as a result of the rear wheels locking, increasing the risk of a crash.
