How Tight Should the Handbrake Be Pulled?

[ElliottRose]

When parking, the handbrake should be pulled to about 70%, which is the optimal working point for the handbrake. If parking on a slope, it can be pulled tighter to prevent rolling backward, while on flat ground, pulling it to about 70-80% is sufficient. Loss of Return Spring Function: The handbrake has its own independent braking mechanism. When the handbrake is not in use, the brake shoes automatically return to their position via the return spring. If the handbrake is frequently used at full force (100%), the return spring will be subjected to high-intensity stretching, which over time may cause it to lose its return function. Shortened Lifespan of the Handbrake Cable: The handbrake cable appears to be a solid steel wire, but inside it contains nylon material, which plays a crucial role. If the handbrake is consistently pulled to its maximum (100% force), the nylon material will gradually lose its elasticity and eventually become ineffective.
