Mazda (north America),inc reported this defect to federal regulators on Feb 28, 1996 and put the number of vehicles at risk at 2,500. The repair is free for as long as the recall stands.
The defect
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.
The risk
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.
The remedy
DEALERS WILL REPLACE THE POWER BRAKE VACUUM BOOSTER ASSEMBLY.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 96V024002.
