Rear Disc Brake Groan/Squeal (Install New Rear Brake Pads)

Some customers may comment on an audible groan/squeal type noise coming from the rear of the vehicle during a light brake apply. This condition is most likely to occur after the vehicle has sat overnight and may be apparent in either forward and/or reverse gears.

This noise may be generated at the rear brake pad/rotor interface during a brake application. The noise is then transmitted into the vehicle's underbody through the rear suspension components.

Replace the existing rear disc brake pads with those found in service kit, P/N 18023377, following the service procedure in the Disc Brake sub-section of the Service Manual.

Parts are currently available from GMSPO.
