Brake lights on - what car owners need to know
(Baonghean.vn) - Brake lights are a particularly important part for the safety of people in the car because they have the function of signaling the driver to slow down or stop... Therefore, you need to learn how to handle it every time the light comes on. Don't ignore it, for the safety and "health" of the car.
1. Handbrake not fully pulled
 |
When the brake light is on, it is best not to continue driving, as this can damage the brake pads and rotors. Most likely, the reason is that you forgot to release (or release) the handbrake, the handbrake helps the car not roll on a slope, or in a dangerous situation where you want to stop but the foot brake does not work, you use the handbrake.
2. Regarding the anti-lock braking system
 |
On many modern vehicles today, anti-lock braking systems are equipped to help prevent the wheels from locking and the tires from losing traction in slippery situations, and this system often has a separate warning light.
However, depending on the situation, the brake light may come on, most of the time the cause of the problem comes from the sensor. An auto technician can check, find the cause and help you find a solution.
3. Low brake fluid level
 |
On many vehicles, an exclamation mark "!" appearing on the gauge can indicate that the brake fluid level is low. If the exclamation mark is yellow, the brake system may still have enough fluid to function. If it turns red, you should take the vehicle to a repair shop as soon as possible.
The phenomenon of brake lights coming on when you just start the engine or when the car just restarts after stopping is very likely related to brake fluid. You need to check the fluid in the tank again, mostly because the fluid has run out and fallen below the "Add" line.
Lack of oil causes the brake light to come on as a warning when the engine starts. To fix this, let the engine cool down, add oil up to the Add line to get the right number.
4. Broken brake light bulb

A lit brake light can also be an explanation for your car's brake lights being burned out. To check, you can ask a friend to stand right behind the car and check if the brake lights come on when you press the brake?
Brake lights aren’t the only thing to look out for. Checking the dashboard for warning lights and noting when and how bright they are is also a good way to diagnose your car.
