“Operator reported that under braking, they lost all power assist to the brake pedal and brake pedal was extremely hard to push. This resulted in extended stopping distance and difficulty slowing the vehicle down. It was found that the vacuum pump had failed”
“The brake pedal suddenly became very stiff with no warning while driving at highway speeds. Braking was very difficult and required me to swerve into another lane to not impact a car and run a red light. I managed to stop afterwards”
“Vacuum pump busted as shown in photos. Once that busted it sent metal shrapnel into the engine which broke a piece of the cam shaft into bits. There were metal fragments that had to be meticulously cleaned out of my engine block”
