9999 BENDIX DASH CONTROL VALVE Recall

Campaign:: 08E018000 on 02/20/2008
Component:: Parking brake:conventional:air
Manufactured:: 01/02/2008 - 01/21/2008
Affected:: 1,457
Defect:: Bendix is recalling 1,457 mv-3 dash control valves manufactured from january 3 through january 22, 2008. some of the units were sold for oem applications on new motor vehicles and some were sold for aftermarket replacement equipment. an incorrect core pin in the injection mold of the molded valve body was used causing the valve body to be oversized in the double check valve seat area. this condition can allow the rubber double check valve to become lodged in the body opening under certain circumstances.
Consequence:: If the double check valve becomes lodged, in the event of a primary reservoir failure, air pressure can leak past the lodged double check valve thereby depleting the secondary reservoir, causing a reduced ability for modulating the emergency brakes.
Correction:: Bendix will provide a remedy without charge for all affected mv-3 valves. bendix will notify vehicle manufacturers immediately. owners may contact bendix at 440-329-9000.
Notes:: Customers may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to http://www.safercar.gov.
