Very VERY off topic but just to show how fast things can go wrong. My Uncle a mechanic by trade for all his life was doing a brake job (front disks) for my Dad on his motorhome at Dads house. My Dad was sitting there keeping him company and my Uncle dropped the back pad while sliding the caliper into position. He picked it up and put it back in the caliper and finished the job. We left for Ocean City the next evening and we would stop for the night at Breezewood. It was mostly all turnpike and while were eating my Dad said his brakes were noisy. I climbed under the motorhome to take a peak and couldn't believe what I saw. The brake pad was installed with the metal side towards the rotor. I didn't have the proper tools to do the job so a shop at the bottom of the hill flipped it around to get us going. Had to buy new rotors and new pads when we got back home from vacation. You now what they say, poop happens.
