If an emergency brake is stuck, it may help to pump the regular brake a few times, lubricate the emergency brake cable or release button, or locate a repair manual for vehicle-specific instructions. If the car changes gears, shifting the gear from drive to reverse a few times may also loosen the emergency brake.Know More
There are a variety of methods that can possibly fix a stuck parking break. The wheel that is seized with the brake should be identified, and the car should be securely supported on a jack. The seized wheel should be removed so that the brake is visible. Gently tapping the brake with a hammer helps remove any adhesions. The cable may need to be replaced because the parking brake can become stuck due to a faulty cable or faulty calipers. The cable can rust and wear down over time.
The symptoms of a faulty emergency brake include a very heavy brake pedal, a burning smell from the front tires, and dark, dirty brake fluid. Replacing the brake fluid can also help keep the emergency brake lubricated. After going through below-freezing temperatures, the cable can freeze and remain in place even when the emergency brake handle is lowered.Learn more in Brakes

Air-over-hydraulic brake systems operate using a combination of compressed air and hydraulic pressure, and the release of the air and hydraulic pressure engages the master cylinder. It then applies pressure to the valves, and the brake fluid is released. The brakes then exert friction on the tires, which stops them.Full Answer >
