Parking brake does not fully disengage. This causes the rear brakes to wear prematurely and also has the potential to generate excessive heat.

I parked at the top of my driveway at a slight incline position with the emergency brake engaged and the car was in second gear (manual transmission). It was in a stationary position at that time. My family exited the vehicle and we went inside our home. Approximately a half our later I notice my car rolled down my driveway and crashed in between two trees on my property. Either the emergency brake failed or the car's transmission failed while parked. The car was found at the bottom of my property still in gear and had the emergency brake in the engaged position.

Parking break doesn't disengage correctly causing brakes to wear down quickly. Water getting into rear break calipers making them defective. This has happened mainly in city street driving but noticeable on the highway.

My passenger rear caliper froze causing the pad on the outboard side to wear down to metal while the inboard pad still had half of its life left. This is behavior similar to NHTSA recall 17V393000 but my VIN does not fall within the parameters of the recall. The vehicle has 58,000 miles on it and is driven mainly on the highway.

- El Paso, TX, USA

In August I received notice of a safety recall because of a brake problem. The letter instructed us to wait for notification that parts are available. It has been nearly two months since I got the notification. I have called the company, and they tell me that the parts are still not available. Because the brakes are an important part of safety, it seems to me that Mazda has not performed the repairs in a timely manner.
