My left front brake sometimes shudders, mostly at very slow speed. Maybe the ABS?
A few months ago there was grease on the wheel cover and the mechanic said the grease cap had come loose; he reseated it.
Could there be grease on the sensor? Can it just be wiped off with a degreaser?
My grandson is willing to check my brakes but I don't think he's up to speed on sensors.
