The short answer

NHTSA received MAZDA NORTH AMERICAN OPERATIONS’s report on Mar 7, 2000. Copied from NHTSA on Oct 20, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

THIS CONDITION COULD CAUSE REDUCED BRAKE EFFICIENCY, INCREASING THE RISK OF A CRASH.

VEHICLE DESCRIPTION: PASSENGER VEHICLES.

CERTAIN RESERVOIR TANK CAPS ON THE BRAKE MASTER CYLINDER WERE PRODUCED WITH A WORN OUT DIE AND LACK VENTILATION HOLES.

AS A RESULT, THE PRESSURE IN THE RESERVOIR TANK CAN DROP GRADUALLY AS THE BRAKE PAD OR SHOE WEARS AND AMBIENT TEMPERATURE DROPS.

ALSO, THE PRESSURE COULD REACH A POINT THAT THE BRAKE CALIPER AND DRUM CYLINDER ARE PULLED BACK BY THE VACUUM IN THE RESERVOIR TANK WHEN THE VEHICLE IS PARKED FOR A LONG TIME.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
