Toyota Highlander rear driver brake caliper locking issue despite replacement on Toyota Highlander

Some Toyota Highlander owners report experiencing rear driver brake caliper locking issues even after replacement. These problems may stem from malfunctioning caliper pistons, which can lead to uneven braking. Additionally, if the replacement caliper is not functioning properly or was not installed correctly, it could contribute to the locking issue. Owners also note that understanding the brake system components, including brake pads and rotors, is crucial, as any faults in these parts can result in braking problems. Furthermore, issues with brake fluid levels, ABS system malfunctions, or overheating can cause brakes to lock up, making it essential to ensure the ABS system is functioning properly. Lastly, some owners have identified problems with the parking brake, such as a stuck caliper or malfunctioning EPB actuator, as potential contributors to the locking issue. Thorough inspection of all related components is advised to identify and resolve the root cause for safe vehicle operation.
