It's a highly prized and very rare option, quick release calipers. I'm really surprised it stayed on as long as it did; every time I've left a tool somewhere it invariably clunks rattles and launches through a piece of glass or something valuable.
Related "left a tool" story: When I was fresh out of college I bought an el cheapo 50-piece-ish socket set to work on my car -- probably swapping an alternator. Drove off with the socket set on the roof. Hung a left and heard them falling off the roof. Circled back and all but 4 or 5 had gone down a storm drain.
I dropped a rubber mallet behind a wall i was patching once. I couldn't reach it, so I just left it their and sealed up the hole in the wall. I wonder if anyone will ever find it.
In a customers house. Dropped my mini mag light in a hole while looking down through a top plate from the attic. Trying to fish a T stat wire up. Took a quick measurement from the nearest stud nails, went down marked the spot and pulled the base board. cut a small hole and there it was! Base board back on like it never happened.
Wait until you forget a magnetic light or even worse, a Snap On battery ratchet with the magnetic battery. You look after you send the car out and can’t find it, buy a new one to replace that one. Then a month later the car comes back and you would be lucky if it’s still there.
Did an oil change and tire rotation on a customer’s Toyota Sienna mini van. Found the lug nut key lock next to the lift about 30 minutes after she left. Called and had her come back to pick it up. Turns out I left the correct key lock on one of the front wheels. She drove 5+ miles with it on and it didn’t come off.
