E-Brake Buttons

To lock the wheels in place, the emergency brake disengages the hydraulic braking system of your car. Cables that are fastened to the emergency brake lever are used by this mechanical device. When the drum brakes on an automobile are engaged, another lever is pulled, applying pressure to the brake shoes to hold the car in place.
When the parking brake is applied to a car with disc brakes, a corkscrew mechanism is triggered, which forces a piston into the brake pads to stop the automobile.
