What is the difference between engine braking and parking brake?
1 Answers
Engine braking and parking brake differ in their meanings: engine braking belongs to the foot brake; parking brake is the handbrake. Engine braking utilizes the compression resistance, internal friction, and intake/exhaust resistance generated by the engine's compression stroke when the accelerator pedal is released without depressing the clutch, thereby creating a braking effect on the driving wheels. The function of the parking brake is to provide resistance to the car when parked, preventing it from rolling. The parking brake, also known as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. The force of the parking brake is much smaller than that of the service brake, just enough to prevent the car from rolling on a slope.
