Condition

Some customers may comment on a Replace Brake Pad or Service Brake Pad Life
System message displayed at very low mileage.

Cause

The cause of the condition may be a calibration in the brake pad life monitoring system
that reduces the calculated pad life too quickly.

Correction

Verify the condition above and check the mileage of the vehicle then follow the Service
Procedure below.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
