| 04-004-21-3821 | 2021-10-02. Service bulletin. PARKING BRAKE:ELECTRICAL; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. Some vehicles may exhibit: Vehicle body vibration when moving from a stop while using the Electric Parking Brake (EPB) automatic release function. Uneven rear brake pad wear. These concerns may be caused because the automatic EPB caliper release timing is too late for the movement of the vehicle. NOTE: Frequent usage of the EPB automatic release function may promote uneven rear brake pad wear. To eliminate these concerns, the EPB control module logic has been modified. |
