Passenger Side - rear brake line failed. Upon inspection the brake line rotted out at 4 way junction box - just in front of the rear tire- passenger side. Had to remove the plastic shield to get to the problem. I was driving at the time when it failed. Pretty scary as the car almost did not stop. I lost about half of the brake fluid. I know Subaru of America had a recall and this car was inspected years ago. Their fix was to spray a wax coating on the lines. They should have replaced the brake lines on all the cars subject to the recall. There is obviously an issue here with the quality of the lines they used as I see that 2005 to 2009 subarus have this problem. Safety put me or others at risk - yes

While coming down a hill, I applied the brakes, and suddenly lost all brake pedal pressure, only being able to stop using a handbrake. This complete loss of the braking system put me and other drivers at risk. Had I been traveling at higher speeds, an accident could have occurred. The brake system warning light came on at the same time as I pumped the brake pedal, and there were no prior indications that the brake system was about to fail. When I inspected the car for fluid leaks, I found that the brake master cylinder was empty and a lot of fluid had collected just in front of the rear passenger-side wheel. The brake line union block at the rear of the car was severely corroded as were the brake lines into and out of the union block. This exact problem was supposedly addressed by NHTSA recall 14V-311 (Subaru Recall WQK-47). The fix involved either applying an anti-corrosion coating or replacing the faulty brake lines. The recall was marked as completed in 2014. However, the completed recall did not prevent the problem from recurring. Since the recall was marked as "completed", Subaru has refused to conduct necessary repairs on the vehicle. This is a known failure point and serious safety concern in many Subaru vehicles, acknowledged by both NHTSA and Subaru. I claim that the fix completed under the recall was insufficient in preventing brake line corrosion and failure.
