The 1999 Mazda 626 has 3 recalls, the most serious being a brake master cylinder reservoir cap that lacks ventilation holes, causing vacuum to build up and pull the brake calipers back, which reduces braking efficiency and raises the risk of a crash.
The braking issue is the only brake-related recall here, but it is worth understanding the full consequence: as brake pads wear down over time and temperatures drop, the sealed reservoir loses pressure. After the vehicle sits parked for an extended period, that vacuum can retract the calipers and wheel cylinders, meaning the brakes may feel sluggish or unresponsive when the driver first applies them. On the engine side, the timing belt tensioner contains an external spring that can break and get caught in the timing belt, potentially stalling the engine without warning while driving.
At a glance
What can fail
The external spring in the timing belt tensioner may break, which can cause the timing belt to lose proper tension.
What the fix does
Dealers will inspect the tensioner and replace it if your vehicle has the affected part.

At a glance
What can fail
The brake reservoir cap may lack ventilation holes, causing pressure to drop as brake pads wear and temperature falls. A vacuum can form in the tank when parked, pulling back brake calipers and cylinders, reducing braking power in early applications.
What the fix does
Brake reservoir tank caps will be inspected for proper ventilation holes and replaced if necessary.

At a glance
What can fail
Some brake master cylinder reservoir caps lack proper ventilation holes due to manufacturing defects. This can cause pressure to drop gradually as brake pads wear and temperature drops, potentially creating a vacuum that pulls brake calipers and drum cylinders inward during extended parking.
What the fix does
Dealers will inspect the reservoir cap and replace it if necessary.
