Condition
Some customers may comment on a moan/groan type noise coming from the rear of the vehicle that is heard in the vehicle's passenger compartment. This
condition is most apparent during moderate brake apply; when the vehicle is slowing or approaching a stop and typically does not occur on a brand new
vehicle.
Cause
This noise may be generated at the rear brake pad/brake rotor interface during a brake application, which is transmitted into the vehicle's underbody
through the rear suspension components.
Correction
Replace the existing rear disc brake pads with P/N 18023377, following the service procedure in the Disc Brakes sub-section of the Service Manual.
Important:
When the new pads are installed, the burnishing procedure indicated below, MUST be performed in place of the procedure described in the Service
Manual. Proper burnishing is essential to insure elimination of this moan/groan noise.
Burnishing Procedure
Make four stops from 50 mph (80 km) with heavy/aggressive pedal apply, followed by four stops from 30 mph (48 km) with medium/moderate pedal
apply. Do not overheat the brakes.
