NHTSA Campaign 96V024002

SERVICE BRAKES, HYDRAULIC:POWER ASSIST:HYDRAULIC

Issued by MAZDA (NORTH AMERICA),INC · Reported Feb 28, 1996 · 2,500 vehicles affected

What's wrong

THE STUDS WHICH ATTACH THE BRAKE MASTER CYLINDER TO THE POWER BRAKE VACUUM BOOSTER ASSEMBLY CAN DEVELOP STRESS CORROSION CRACKING AFTER BEING OPERATED FOR AN EXTENDED PERIOD OF TIME IN THE SOUTHERN CALIFORNIA LOCATION.

Consequence

IF A CRACK OCCURS, IT COULD RESULT IN ONE OR BOTH STUDS FRACTURING. THE MASTER CYLINDER COULD THEN SEPARATE FROM THE VACUUM BOOSTER, WHEN THE BRAKES ARE APPLIED, PREVENTING THE SERVICE BRAKES FROM FULLY ACTIVATING INCREASING THE RISK OF A VEHICLE ACCIDENT.

Remedy

DEALERS WILL REPLACE THE POWER BRAKE VACUUM BOOSTER ASSEMBLY.
