MATERIAL AVAILABLE)
MODELS/YEARS
1990 SILHOUETTE
NUMBER:
90-T-153
CORP.REF.NO: 035003
DATE:
August 1990
SECTION:
5
CONDITION:
Some 1990 Silhouettes may experience a high pitched squeal coming from the front of the vehicle during light to moderate brake applications. The
squeal may be more noticeable during warm weather or periods of heavy brake usage.
CORRECTION:
A new front brake lining material composition is now available that may help reduce this brake squeal. The new material entered production with VIN
LT315560.
Rotors should be inspected and refinished only if required.
During routine brake maintenance such as pad replacement, DO NOT refinish disc brake rotors unless:
1.
There is brake pulsation present, and the pulsation is determined to be caused by the rotors, or
2.
The rotors are excessively scored. Light, surface scoring that does not exceed 0.015 inch should not affect brake operation.
