On some 1987-90 Skylark, Skyhawk and Century models, customers may comment of a rattle or buzz type noise that seems to come from the instrument
panel area in front of the driver. The noise is most likely to occur during brake apply or release, during low speed or parking lot maneuvers.
To repair this condition, install a new brake booster check valve, P/N 18012017.
Parts are currently available from GMSPO.
