Should I engage the handbrake after shifting to P mode?
2 Answers
Generally, when parking on a slope to prevent the car from rolling, it is common practice to both shift to P mode and engage the handbrake. Introduction to the handbrake: The professional term for the handbrake is auxiliary brake. Unlike the principle of the main brake, it uses a steel cable connected to the rear brake shoes to apply braking force to the car. Long-term use of the handbrake can cause plastic deformation of the steel cable. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel distance will also increase. How the handbrake works: For small cars, some handbrakes are located behind the transmission, where there is a brake disc connected to the drive shaft, similar to a disc brake. The pulling force is transmitted there via a steel cable to achieve parking braking.
As a seasoned driver with over a decade of experience, I always engage the parking brake after shifting to P. This isn't just a habit - it's crucial for vehicle protection. While it might seem unnecessary on flat roads, its importance becomes obvious on inclines: the P position relies solely on transmission pawls for locking, and prolonged stress on this mechanism can accelerate wear or cause unintended rolling. I once experienced slight vehicle movement on a steep mall ramp after engine shutdown when I forgot the parking brake - thankfully I reacted in time. Developing this habit extends vehicle lifespan and reduces repair costs, especially now that electronic parking brakes with auto-engagement are common (though manual operation shouldn't be neglected). Safety first - an extra layer of protection always brings peace of mind.
