Affected Component: SERVICE BRAKES, AIR:DISC:PADS

Summary

SOME VEHICLES MAY EXPERIENCE A SQUEAKING/GRINDING NOISE FROM THE REAR BRAKE EVEN AFTER THE BRAKE PEDAL IS RELEASED. UPON INSPECTION, THE CALIPER MOUNTING SUPPORT IS CORRODED AND THE DISC PAD IS ABNORMALLY WORN OUT (A). THIS IS CAUSED BY VEHICLE USAGE IN AN AREA USING ROAD SALT. THE SURFACE OF THE MOUNTING SUPPORT MAY SWELL FROM CORROSION CAUSING PREMATURE DISC PAD WEAR AND BRAKE NOISE. TO CORRECT THE PROBLEM, AN IMPROVED CALIPER MOUNTING SUPPORT HAS BEEN NEWLY ESTABLISHED AS A SERVICE PART. THE ANTI-CORROSION SURFACE TREATMENT HAS BEEN CHANGED FROM ZN TO ZN-NI PLATING.
