Affects Mazda MPV · 1989 — about 2K vehicles.

The hazard

CONTAMINATION OF THE VACUUM BRAKE HOSE CHECK VALVE BY DETERGENT USED IN MANUFACTURE, COULD CAUSE THE VALVE TO STICK AT LOW AMBIENT TEMPERATURES THEREBY PREVENTING ITS OPERATION. RESIDUAL VACUUM IN THE POWER BRAKE SYSTEM WOULD PROVIDE POWER ASSIST TO THE BRAKES ON INITIAL APPLICATION, BUT THE STICKING VALVE WOULD PREVENT VACUUM BUILD-UP TO PROVIDE CONTINUED POWER ASSIST. THIS COULD RESULT IN INCREASED STOPPING DISTANCES AND A POSSIBLE VEHICLE CRASH. CORRECTION: VACUUM BRAKE HOSE AND CHECK VALVE ASSEMBLY WILL BE REPLACED ON AFFECTED VEHICLES.
