This TSB article is intended to give a technician information regarding brake repairs to help reduce unnecessary repairs.
Refer to the following list when performing brake repairs.
Where rotors are the causal part, linings should only be replaced if they are damaged, e.g., cracked, taper wear, heavily grooved, etc., or if specifically instructed in a TSB.
Where linings are the causal part, rotors should not be machined unless they are heavily grooved or if specifically instructed in a TSB.
Other exceptions would include instances where the non-causal parts are found to be below minimum serviceable thickness or if the technician estimates that the parts will not last until the next service interval. Since these parts are classified as wear items (such as: linings, pads, rotors, and drums) replacement is not covered under warranty.
