While backing up. brake pedal went all the way to the floor and was unable to stop. managed to get it to stop. i have heard about a brake booster issues.
I only have 57,000 miles on my truck, which is why i am reporting this. the truck turns off completely. i have been going to make a right/left turn and the truck shuts down completely. i have no power steering and limited brakes. this has happened to me twice now. i am lucky enough that i am strong enough to turn the truck without power steering otherwise i would have hit vehicles both times this happened. there has to be some type of electrical flaw that is making this happen. i want to get this resolved before my insurance company has to get involved because i am in a car accident. if this is something the manufacturer takes care of that would be great, otherwise i would just like to know if someone else has had this issue and has found the resolution.
When coming to a stop the brake pedal gets hard to depress and the rate of deceleration chages makes it hard to jusge when and where the vehicle will end up.
While in a drive through i was creeping up and when trying to come to a stop my brake pedal would not depress all the way as normal and took a longer than normal time to stop even with both feet pushing on the brake pedal. i ended up rolling into the car in front of me. i took the car to the dealership the next day and was told that my vacuum pump/brake booster needed to be replaced.
