“Brake booster and brake booster pump failure”
“My ability to break unexpectedly stopped working while I was on the highway during morning, rush-hour. I was going 55 mph on the highway at the time and luckily, I was on an uphill incline when they went out, thus allowing me to be able to ‘naturally’ slow down”
“The contact owns a 2011 Toyota Prius. The contact stated that while driving at 60 MPH, the brake pedal was depressed but hesitated to respond”
