NHTSA Campaign 84V068000

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:MASTER CYLINDER

Issued by GENERAL MOTORS CORP. · Reported May 29, 1984 · 32,010 vehicles affected

What's wrong

UNWANTED AIR IS BEING DRAWN INTO THE BRAKE SYSTEM WHEN BRAKE PEDAL IS RELEASED. THIS IS DUE TO THE USE OF THE BENDIX MASTER CYLINDER IN COMBINATION WITH THE BENDIX HYDROVAC.

Remedy

DEALER WILL CHECK TO SEE IF VEHICLE IS EQUIPPED WITH A BENDIX MASTER CYLINDER. IF SO, DEALER WILL INSTALL A TUBE AND HOSE ASSEMBLY AND REPAIR BRAKE SYSTEM. IF NEEDED, A NEW WAGNER MASTER CYLINDER WILL BE INSTALLED.
