Missing brake pad? Reminds me when I bought a brand new 4-wheeler Dodge PU back in 1976. When I complained to the Dodge dealer about the breaks pulling I was told its normal ; when I complained about going through (not burning) a lot of oil, I was told that was normal.
Turned out that the rotors were on backward (as I recall), and the rings on the pistons were in a line, so the oil just poured through. Seems there was a strike at the factory and these things were deliberately done by the workers.
Had a 81 Ford F-100 Stepside that had NO rear axel oil seal on one side......................
“Turned out that the rotors were on backward (as I recall), and the rings on the pistons were in a line,”
Both of those are practically impossible. Piston rings rotate, that part of the reason for the crosshatch hone pattern. Rotors cannot be installed backwards, the offset wouldn’t allow caliper installation.
