Re: [DML] Re: Steering column vibration when braking

[Paul Gress <pgress@xxxxxxxxxxxxx>]

It means "wobble" (if the rotor is warped).  You need to put a dial indicator on one of the surfaces the brake pads contact then spin the rotor.  The radial run-out will then be indicated.  There are specifications for maximum allowed run-out but I don't recall that number.  Maybe some else may recall or you'll have to research it yourself.
