If you are cut by a sharp object, the first time you apply the brakes after being cut, you will feel it (the brakes are much softer than usual {this can also be a lack of brake fluid), because the brake hose will crack directly. If the brakes are not working well when you are traveling, don't be nervous and don't step on the brakes too hard (then it will only make the brake fluid leak all the way out), don't pull the hand brake at high speeds, drive the car to the side of the road and turn on the emergency lights and step on the brakes a little bit (soft brakes can be just a bad thing, the brakes on other wheels may work well when there is brake fluid), and you can pull the hand brake at low speeds to stop the car).
Brake hose note: brake hose pressure is very high, it is the use of raw materials demand is also very high, but it is a rubber parts will have aging, such as cracking and bulging, so we need to check regularly. Problems found in time to replace.
