SEPHIA - FRONT BRAKE NOISE





This Bulletin provides information about front brake caliper anchor and brake pad changes involving specific Sephia models (refer to VIN range and information provided below).

Some Sephia models produced between May 26, 1995 (VIN KNAFA121XS5230537) and January 10, 1996 (VIN KNAFA1257T5247655) may experience a front brake "squeal" or "groan" noise at low speed during light to moderate braking. The cause of the noise is related to clearance deviations between the front brake caliper anchor and the brake pads.

If you receive a customer complaint concerning brake noise ("squeal" or "groan") in the vehicle production range above, replace the front brake caliper anchors and brake pads using the procedure provided.

Notice:
The information provided in this Bulletin applies only to Sephia models from VIN KNAFA121XS5230537 to VIN KNAFA1257T5247655.
