NHTSA Complaint #11610912 — 2015 CHEVROLET SILVERADO 1500

While in a drive thru moving up slowly to the next spot brakes became hard and had to put a lot of force on the brakes to make vehicle slow down and stop. I thought I was going to hit the car in front of me but luckily stopped within a few inches. Took it in to get serviced and mechanic said brake system checked out to be good. That was 2 years ago. This last week I was backing in a boat in the water and the brakes became hard to push and was not slowing the vehicle down. I had to put on the emergency parking brake in order not to go in the lake with the truck. It was a very scary situation with my small nephews in the back seat. I was able to drive the truck back 10 homes from Canada. This appears to be a requiring issue from complaints on this make and model of truck.
