Under some conditions your parking brake can freeze in the engaged position. This is most likely to happen when there is an accumulation of snow or ice around or near the rear brakes or if the brakes are wet. When there is the risk that your parking brake may freeze, temporarily apply it with the shift lever in P (Automatic Transmission) in first or reverse gear (for Manual Transmission). Also, block the rear wheels in advance, so the vehicle may not roll. Then, release the parking brake.
