5 reasons why cars lose their brakes and how to handle them
(Baonghean.vn) - One of the scariest things that can happen when driving a car is losing the brakes. This phenomenon can easily cause the driver to lose control and panic, especially for new and inexperienced drivers.
To avoid car brake failure, you need to know the cause, which can be due to the driver or the brake system itself.
1.One of the most common causes isloss of brake pressure. The brakes operate using hydraulic pressure within the system, so if there is a brake fluid leak in the brake line or brake cylinder, the brake system will not have enough pressure to perform deceleration.
When a serious leak occurs, the brake fault indicator light will illuminate to warn you and the vehicle will be unsafe to operate in this condition.

2. Check the brake fluid reservoir,If the fluid level is too low, it means there is a serious brake fluid leak., the entire brake system needs to be checked to find the leak and fix it. There are many causes of leaks, but if the brake fluid level is too low, it means that the rubber seal in the brake system is broken or the oil pipe is rusted.
Brake lines are made of copper and can corrode quickly in certain places, over time they will wear out and become of poorer quality than other places on the oil line, so the brake fluid will leak and the vehicle may lose its brakes.

3.If you step on the brakes but it doesn't work very well, it could beThere is air in the system.. At this point you need to bleed the brake system to remove air bubbles. Sometimes it can also be due to a damaged piston inside the master cylinder.
4.Another possible cause of brake failure isABS controller failure. Due to the leak, the internal pressure is reduced and the brake pressure cannot be fully transmitted when the brake is applied.
Contaminants in the brake fluid can also enter the controller and prevent the inlet-exhaust valves from opening and closing, causing brake failure.

5.The cause of brake failure can also be caused by the driver, that isbrake continuously for a long time(usually occurs when the vehicle is going downhill on a mountain pass) causing the brake pads to burn, resulting in poor braking performance.
To avoid this, the driver should not apply the brakes for a long time, instead using the engine to slow the vehicle (by shifting into a lower gear).
