Does anyone here have any clues as to why the rotors on my 83 bronco get out of whack causing severe shudder when braking? When it first occured I put new rotors on and about a year later when the shudder got so bad again I had these machined true. This was fine for a while but the problem gradually returned and I just got the truck back from another machining. The bloke at the brake place reckons the problem is closer to the centre rather than the outer diameter of the rotor and he can't offer a cause.
