88 245 DL, 250k miles...
it's beginning to show vibration / shudder when braking which comes with a brake rotor probably out of true.
I remember a diagnosis trick, vaguely, when trying to determine whether its the front or rear rotor. Something like: vibration only = rear; vibration + pulsating pedal = front. Or is it the other way around?
I know the only way to really nail it down is with a dial indicator gauge to determine amount of the rotor's run out. Except I don't have one handy.
comments?
Thanks
Robert
