1994 Mazda B2300

Component

Service Brakes, Hydraulic:Power Assist:Hydraulic

Consequence of 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.

Corrective Action

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.

Recall Notes

dealers will replace the power brake vacuum booster assembly.

1994 Mazda B2300

Component

Parking Brake:Conventional

Consequence of Defect

the parking brake control self-adjust pawl does not line up properly with the self-adjust rachet causing the pawl to slip over one or more teeth in the rachet.

Corrective Action

when the above occurs, it can result in parking brake system ineffectiveness. the parking brake will not hold the vehicle, causing the vehicle to roll freely, if the transmission is not left in gear.

Recall Notes

a wedge will be installed which will serve to lock the parking brake self-adjust mechanism pawl into engagement with the rachet. also, owners will be advised to release and reapply the parking brake whenever tooth skip occurs and will be reminded to always turn off the engine and leave the vehicle in gear when the vehicle is parked.
