Brakes
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 ACTIVATING INCREASING THE RISK OF A VEHICLE ACCIDENT.
Ford has recalled 1991-1994 Explorer and Ranger trucks because the bolts that mount the master cylinder to the brake booster may fracture. If these bolts fracture, brake loss could occur. Dealers will replace the power brake vacuum booster assembly.
