What owners wrote

The brakes failed as my son approached an intersection. Subsequently, he struck another vehicle broadside. Extensive damage was sustained to both vehicles. The driver reported that he pressed the brake pedal, but the truck would not stop. After I investigated further for an explanantion,I discovered that there was a recall on his brake system that might explain brake failure. The crash occurred on a city street.

Reported at 150,000 miles, September 2020 CrashInjury

Brake vacuum pump booster. First started when driving under 5 MPH. The brakes were hard to push down and would not stop the truck properly. Did this for approximately 3 months. Then driving getting off the interstate and applied brakes going 60 MPH the brakes would not work. Could barley stop. Same issue has when driving slow. Now the brakes will not work at any speed. They truck is undrivable until it gets fixed.
