Service brakes, hydraulic:foundation components
Model years: 1999, 2000
Problem: 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.
Fix: Dealers will install improved pcrv's in the rear brake system. This recall was expanded in september 2000 to include 1999 and 2000 ford contour, mercury mystique and cougar vehicles.
