How to know if the car brake system is working safely?

(Baonghean.vn) - The car brake system is an important part in the operation and safety of the vehicle. To ensure the good working condition of the vehicle, inspection must be done regularly. Some experiences below will help you do this quickly and accurately.

Test the brake pedal before starting the engine.

Before starting the engine, press the brake pedal 3-5 times. If the brake pedal hardens and stops, the brake booster is still working properly. When the engine starts, the brake pedal must slowly lower to its original position and not stay still.

If you don't start the engine but the brake pedal feels weak and you can't press it as many times as you want, it means the vacuum assist system has lost its effectiveness. At this point, it's best to call a mechanic to check it on the spot or call a tow truck. Don't risk taking the car out on the road.

Check the ABS warning light

When the ignition key is turned on, the ABS anti-lock braking system indicator light will come on, indicating that the electronic system is being checked. If the light comes on for a few seconds and then goes off, it means the brake system has been checked and there is no problem.

If the ABS light flashes or stays on continuously, the user should take the vehicle to a qualified workshop for inspection.

Hear the brakes

There will be a type of noise that appears if your car brakes have a problem, a squealing sound, or a metal-on-metal sound is a sign that the brake pads are worn. This noise will get louder the more you use the brakes.

Check brake pads

This is a very important part in reducing the speed of the vehicle, ensuring the safety of people and vehicles. If the brake pads are worn deeply, it will directly affect the deceleration or stopping of the vehicle.

Brake pad wear depends on each person's driving style. When operating, if the brake pads wear too much, it will reduce brake pressure, reduce braking performance and heat the brake disc, along with that, the brake disc will wear out quickly.

According to the manufacturer's recommendations, do not go too far if the brake pads are worn out, and replace the brake pads when the thickness is only 2 - 3 (mm).

Brake disc smoothing

After a long time of use, under the impact of brake pads, external environment such as dirt, soil, rocks... When braking, the working environment of the brake disc and brake pads is very harsh because the surface adheres to many impurities along with the large heat generated will cause the brake disc on the vehicle to wear unevenly, or the brake disc may also be warped.

In these cases, smoothing the brake disc is the most effective way to solve the brake problem. For models with ABS braking system, drivers need to pay attention when smoothing the brake disc, must know the minimum allowable thickness, on some models if the brake disc is too scratched and worn, it cannot be fixed by smoothing the disc but must be completely replaced.

Check brake fluid

You should check your car's brake fluid regularly every two weeks to know the condition of the brake system. If the fluid level is lower than the specified level, you need to add more brake fluid to avoid the brake system running out of fluid.

In case of frequent oil loss, it is a phenomenon of oil leakage, possibly in the oil pipes of the brake system.

While checking the brake fluid, you also need to check the color of the fluid. If the brake fluid is new, it will be clear or translucent. If your brake fluid has not been changed for a long time, it will be dark and dirty. If the brake fluid has turned completely dark, it is time to replace it completely. Avoid leaving it for a long time, which can lead to many other dangers./.
