Why Shouldn't You Pull the Handbrake When Going Downhill?

[RuthLee]

When going downhill, due to the significant inertia of the vehicle, using engine braking in second gear provides considerable resistance to the engine, which can cause substantial damage to the engine. The handbrake should only be engaged when parking or in emergency situations; otherwise, it is generally not recommended. Precautions for Using the Car Handbrake: Avoid Pulling Too Tight: Excessive or prolonged stretching of the metal cable can accelerate its deformation and aging, leading to a loosened handbrake or even cable breakage. The handbrake should be pulled up until the rear wheels lock, then lifted an additional 1-2 notches to ensure the vehicle doesn't roll. Avoid Using the Handbrake for Parking on Slopes: Prolonged parking on a slope relying solely on the handbrake will accelerate wear on the handbrake cable. After parking, first engage the handbrake, then place a brick or similar object in front of the downhill-side wheel to secure it. Release the handbrake to transfer the load to the wheel, then re-engage the handbrake.
