Could it depend on the type of brake and the type of oil? Many years
ago, I had a Citroen which had a hydraulic fluid (mineral oil in this
car) hose just in front of the (inboard) disk brakes. When this hose
leaked and sprayed fluid on the rotors, the brakes did not grab, in
fact, I lost most of the braking effect.

Also, could it be that contaminants could initially cause the brakes
to grab, but then (as they heat up, or whatever), lose braking
effectiveness?
