What is the reason for the brake becoming hard after pressing it several times in a row?
1 Answers
The brake becoming hard after pressing it several times in a row may be due to lack of necessary maintenance of the brake system, too much impurities in the brake master cylinder, poor sealing, or failure of the vacuum booster pump. Driving precautions are as follows: 1. Develop the habit of fastening the seat belt when getting in the car: The importance of seat belts for driving safety is self-evident, and many bloody examples have warned that you must fasten your seat belt when entering the car. But there are always some people who feel that the seat belt restricts their activity space or even find it uncomfortable and do not fasten it. 2. Make sure the car door is closed tightly when driving: If you are not sure whether the door is closed tightly, don't be afraid of trouble, you should open the door and close it again with force. For vehicles equipped with a door-not-closed reminder function, pay attention to whether there is an alarm sound or whether the reminder light on the dashboard is on.
