Hi everyone. Back in the spring when covid had us locked down, I performed all the maintenance possible on my truck. I purchased a set of powerstop rotors and pads and after inspecting my original pads and rotors, they were in great shape with 3-4 mm of pad remaining all the way around at 75,000 miles. I am now at 86,000 miles and decided to wait until they needed to be changed before installing the new rotors and pads. I did some towing, not much, and typically I'm easy on the brakes. How long have you all gone on your original pads and is there an sound indicator once they reach a minimum thickness?
