Condition
Some customers may comment that early brake wear occurs when operating in
environments that are muddy, dusty, or corrosive.
– Typically these are in mining or oil field use. Cases in where original linings wear out
under 10,000 miles (16,000 km).
Important: Brake noise or roughness may be experienced with these linings.
There is a rotor and pad set that has a better life expectancy in these environments. The
pad life is influenced by preventative maintenance performed by the customer.
Information
⇒ Ensure standard level of cleanliness is maintained on the trucks. Mud
packing/debris on around the wheel and brake components needs to be
routinely cleaned off to ensure proper brake function with any friction
combination.
⇒ Use of the Semi-met lining must be paired with Non-FN rotor. So the pads
and rotors must be replaced as a set. They should also be replaced at all 4
corners. So do not replace only the fronts or rears to maintain brake
performance.
Note: The brake pad life feature should be disabled using a setting in the DIC.
Instructions are in the owner’s manual under "Brake Pad Life System.
Note: This is a customer pay repair.

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.
