If your vehicle is showing parking brake is stuck and will not release, here are the most likely causes and the parts you'll need to fix each one.
Moisture and road salt can penetrate the protective sheath of the parking brake cable, causing the internal steel wire to rust and bind. This locks the cable in the pulled position, preventing the brakes from releasing.
On vehicles where the parking brake is integrated into the rear disc brake caliper, the mechanical lever on the back of the caliper can rust and seize, locking the brake pads against the rotor.
The return springs and levers inside the parking brake drum assembly can break or rust over time. Additionally, if the shoes were adjusted too tightly during a recent brake job, they can lock up against the drum.
On modern vehicles with an electronic parking brake, a faulty switch (often caused by spilled liquids on the center console) can prevent the system from sending the release signal to the brake motors.
