Having issues with my brakes. After sitting for a while when I start the truck and go in reverse I can feel in the pedal some kind of clunking and the brakes will not stop the truck from rolling backwards. It almost feels like the calipers or the piston or the brake pads are sticking or binding. After hitting the pedal hard more than a few times it goes back to normal. This happens about 3 or 4 times a month but not always. Took it to the dealer and they replaced the booster hose and brake booster actuator. Which would make sense if there was no clunking and it was just tough to push the pedal. Any way it’s done it 3 more times since they did the repair and I dropped it off again. Anyone else experience something else like this?
