When truck is moving forward or in reverse you can hear a squeaking/grinding noise, regardless if I step on break or gas, turn the wheel or not. The noise is constant (warm or cold weather). I took the truck to a local mechanic and he recommended a brake inspection after we test drove the vehicle. I received a call later in the day from the mechanic saying front brakes looked new, rear break pads were worn out and emergency breaks were out of balance. I had brake pads and rotors replaced @ 70K miles (front & back) and at 100k miles now…How can the rear breaks be worn out before the front? I was always told that the front pads go out 2x’s before the rear pads need to be replaced…HELP!!
