Trying to help out a friend of mine whose wife has a 2001 Toy Highlander.
They bought it from the original owner who always had Toy dealer do any work on it.
He said his son drove it the other day and the brakes were making a funny noise. He investigated and found a caliper rotated out away from the rotor to the point it was hitting the rim.
When I heard this I told him it sounded like there's a bolt missing from the caliper. He insisted there isn't one missing.
This afternoon he came over with his camera and here is what he showed me.

Personally, I've never seen a caliper that doesn't have two slider pins/bolts holding it to the caliper bracket.
Can someone explain how this works?
