Some Hyundai Tucson owners report experiencing issues with rear parking brakes seizing after periods of inactivity. These owners often find it necessary to take specific steps to unseize the brakes before replacement, such as placing the Electronic Parking Brake into service mode to retract the caliper pistons. In cases where the parking brake is stuck, some owners have successfully released it by starting the car and repeatedly engaging and disengaging the brake to dislodge any ice or rust. Additionally, proper adjustment of the rear parking brake may be required, which involves blocking the front wheels and raising the rear of the vehicle for adjustment. To prevent future seizing issues, some owners recommend applying anti-seize compound to screw tips to combat water ingress. Following these steps can help ensure the rear parking brakes are functional and ready for replacement.
