I wonder why when you grab that handle on the floor console or between bucket seats and pull on it real hard and the car's rear wheels lock for a moment, then the car spins 180 degrees they call it an "E-brake turn".....................just saying Maybe before the 1966 Federal Motor Vehicle Safety Standards (FMVSS) and the dual chamber master cylinders it was sometimes termed and actually used as an "emergency" brake/braking method but not today. A lot of this is now the Kleenex vs tissue, Xerox vs photo copy, "dialing" a phone number vs pushing buttons to call someone, and a hundred other "genericizations". At one time it was on some vehicles an "emergency" and parking brake but there ain't no way (yep ain't and a double negative ) that cable device is going to stop a vehicle, maybe it will slow it down like a fly on an elephants butt would create wind resistance

From Wiki and "Parking Brake" : The parking brake in most vehicles is still completely mechanical. Traditionally engaged by pulling a lever, the cables manually engage part of the car's braking system, usually the rear disk or drum brakes.[12] The mechanical nature allows the driver to apply the brake even if the main hydraulic brake system fails.[7] Good luck with that
