However,if the brake pads are excessively worn un-evenly, side-to-side or same side/inner-to-outerpads, then consideration should be given to cover this underwarranty since this type of wear is most likely due to poor operation of other brakingcomponents.

Consideration should be given for covering brake pads up to 39,000-km (24,000-mi)(excluding owner abuse, excessive trailering, or the situations that would not beconsidered normal use).Installation of new rotors does not require pad replacement. Do not replace pads unlesstheir condition requires it – excessively worn, damage or contaminated.

Brake Wear:

Several factors impact brake lining wear and should be taken into account when reviewingrelated issues:

- heavy loads / high temperatures / towing / mountainous driving / city driving /aggressive driving / driver braking characteristics (left foot or two feet)


The following are conditions that may extend brake lining wear:

- light loads / highway driving / conservative driving / level terrain

Labor operation 2480018 — Brake Burnish is not a published labor operation and willnot be found in the Labor Time Guide. This labor operation should be used to claimthe necessary time for cleaning up the braking surfaces for thickness variation pulsationdue to “lot rot” corrosion – refer to Brake Pulsation section of this bulletin forprocedure. Thickness Variation Pulsation due to “lot rot” corrosion occurs when vehiclesarenot driven for an extended period of time. This type of corrosion clean-up is coveredunder the terms of the new vehicle warranty coverage.If correcting for LRO, claim the use of correction plates as OLH. The times for usingcorrection plates are not to exceed 0.2-hr for one side and 0.4-hr for both sides.Guidelines for submitting OLH per General Motors Policy & Procedures should be followed.Model years 2005 to current — labor operations 2420670, 2420671 and 2420760, 2420761,are to be used only when replacing rotors.Model years 2005 to current — labor operations 2420672, 2420762, 2430032 and 2430052have been established for Brake Rotor/Drum Refinishing.For model years in which the new labor operations do not apply, the time for refinishingthe rotor is in labor operations 2420670, 2420671 and 2420760, 2420761.
