That's a lot of trucks, and it sounds like 9 instances of failure reported to date.
No accidents reported, but one injury? How did that happen, someone break an ankle from stomping on the brake pedal too hard? I'd think it'd take a while to replace 270,000 master cylinders, and might take a while to get the parts inventory as well.
