The brakes and rotors in the rear of the truck were grinding at 21k miles. brought it to dealership at 23k miles and had to replace rear brake pads and rotors.
The vehicle was going down hill on a very busy highway when we tapped the brakes to slow down and the brakes went to the floor and we skid about 300 yards before being able to get the truck to come to a stop. we kept tapping brakes trying to get them to grab and stop us luckily, the car a head of us turned right at the light so we did not crash into them. then when it did stop the rpm started reeving up and the truck lunged forward then the rpm went down. we were very lucky we did not go through the intersection and wreck.
