常用手闸可以保证它功能正常并可调节刹车闸。

There are two good reasons to use the emergency brake, neither of which have anything to do with preventing the car from moving – the first is that frequent use will prevent it from becoming “stuck” and the other is that it will help keep your brakes adjusted.

There is concern about an emergency brake becoming stuck – but that is generally because of a lack of use and the resultant corrosion of various components. It is unlikely an emergency brake would become stuck in the employed position unless it has been left that way for an extended period of time after not being used.

The second reason for using it is that on the vast majority of vehicles, the emergency brake is used to activate the self-adjusting feature employed in most rear brakes, especially when drum brakes are involved. The frequent use of this system and that feature will ensure the brakes are kept up to snuff.
