After issue with first truck dealership asked to bring in others to be inspected and found same issue with them. Front brake pads were separating from backing. This truck had less mileage so damage not as severe.

Aug 02, 2021

This one was taken in after the first one also for inspection by dealer. Issue wasn't as severe due to lower mileage and use. I believe the pads were just changed as a precaution, I don't believe they had started to separate.
