If you notice the word “BRAKE” shining in red, your automobile needs more brake fluid, according to the brake system warning light. Additionally, this signal denotes a brake system issue. A red automobile battery indicator on your dashboard indicates a problem with the battery or charging system. Charging System Warning Light:

An Engaged Parking Brake
The parking brake sensor will signal the brake warning light to switch on if the parking brake is still engaged. The parking brake on your car should be entirely disengaged to prevent this from happening in most cases.
If you keep it the way it is, you’ll be using your parking brakes all the time, which can cause your brakes to overheat and hasten the wear of your brake shoes and brake pads.
The efficiency of your braking system may be impacted by the accelerated brake fluid deterioration brought on by these elevated temperatures.
Low Brake Fluid Levels
The amount of braking fluid in the system is monitored by a sensor in the brake master cylinder. The sensor will cause the brake light to illuminate if levels are below the minimal threshold.
Low brake fluid levels can be very concerning because they may be a sign of an urgent brake fluid leak.
Worn Out Brake Pads
As the caliper pistons must extend further to make contact with the rotor, worn brake pads might also result in a drop in brake fluid level, which can also activate your brake warning light.
This sensor wire makes contact with the rotor when the brake pads get too worn, which prompts the brake light (also known as the brake pad warning light) to turn on.
Anti Lock Braking System Malfunction
A brake warning light for the antilock braking system (ABS) is present in the majority of automobiles.
Both the brake warning light and the ABS light (if it has one) may turn on in response to issues with the antilock brake system. Electrical problems and even something as simple as a dirty wheel speed sensor can be the culprits.
What does the brake system light imply when it illuminates?
When your brake light illuminates, your automobile is warning you that either there is insufficient braking fluid in your car, the emergency brake is engaged, the ABS unit is having problems, or there is a problem with the sensors.
Driving while the brake system light is on is it safe?
There’s no need to fear if, while you’re driving, the brake warning light illuminates or illuminates and remains illuminated after you depress the brake pedal.
Our vehicle features two independent braking hydraulic systems that connect the brake pedal to the wheels, so even if one of them fails, you will be able to stop your car safely. Be mindful that if only one hydraulic system is used, it could not stop as quickly.
As carefully as you can, drive the car to a parking space or into the shoulder of the road, then gradually apply the brakes to bring the car to a halt. Make plans to bring the car to your preferred repair facility once it has been stopped safely and removed from the flow of traffic.
When the brake system warning light illuminates, what should you do?
If both of these warning lights begin to flash at the same time, there is only one thing to do. As soon as you can, stop the car safely, then dial your breakdown service. If you have both brake and ABS warning lights on, it may indicate a serious problem with your brakes. You will put both your own safety and that of other road users at risk if you keep driving.
While it’s crucial to stop as quickly as you can, keep in mind that your brakes might not be in good condition. Keep your cool and make an effort to slow down gradually. Be careful not to apply the brakes suddenly or forcefully. You shouldn’t use the vehicle again until the problem has been resolved.
What symptoms indicate low brake fluid?
One or more of the following indications may be present if your brake fluid is low:
- Your dashboard lit with a brake warning light.
- Low-quality, filthy, or discolored brake fluid is visible.
- The brake pedal is soft or spongy.
- Vehicle stops more slowly than usual.
Why does my dash have a red brake light?
The amber/yellow brake warning lamp and the red brake warning lamp have different functions. When there is a hydraulic issue, such as low brake fluid or a loss of hydraulic pressure in one of the brake circuits, the red (RBWL) lamp will illuminate. If the parking brake is applied or shorted to the ground, it also glows.
If the brake fluid level is low, it lights. Low fluid level is frequently a sign that the brake pads need to be replaced since they are worn out. Brake fluid accumulates in the space behind the caliper’s piston when the brake pads deteriorate. Before adding fluid to the reservoir, it is crucial to inspect the system for leaks.
Can low tire pressure turn on the ABS light?
Yes, low tire pressure can cause your ABS light to turn on, to give you the quick answer. When braking, the ABS (anti-lock-braking) system is in charge of keeping the wheels on the ground.
This indicates that one of your tires could not be properly inflated. This may also cause the ABS light to illuminate for a number of reasons. Wheel speed sensors are installed in your automobile at each of the four wheels. These sensors track wheel speed and continuously provide this data to the ABS and traction control systems, which are managed by the vehicle’s ECU.
When the ECU detects an anomalous speed under certain circumstances, it activates the traction control or ABS as necessary to adequately and safely control the vehicle. These sensors may occasionally malfunction or stop operating altogether, delivering the ECU erroneous indications. You might encounter the symptoms you’ve mentioned when this happens.
These erroneous or imprecise signals may unintentionally activate the traction control or ABS systems. The change in tire pressure may have also resulted in the ABS light turning on, depending on the signal sent from the wheel speed sensors to the ABS system.
What does it mean to “check brake system”?
Your car’s message center can show a wide variety of warning messages. If you see one that says CHECK BRAKE SYSTEM, it implies that the brake system has been flagged by the car’s computer as needing inspection. The most likely problem is that your brakes need maintenance (fluid topped up, brake pads changed, etc.), but it’s also possible that there’s a problem with the system as a whole. Have your car inspected as soon as possible if the message does not disappear or reappears.
Take any warnings from the brake system seriously. It is crucial to have it done, even if it just requires routine maintenance.
What factors could turn on the red brake warning lamp while driving?
A braking system light may illuminate for a number of reasons, including:
- caution sign for brake fluid.
- warning light for the handbrake.
- The brake lights aren’t working, either one or both.
- damaged or worn brake pads.
- the ABS sensor alert (anti-lock brakes)
- Brake light problems are caused by a low voltage battery.
What causes problems with the brake system?
Your brakes’ ability to work hinges on a number of processes going well. Your brake lines, which contain brake fluid, are subjected to pressure when you depress the brake pedal. The brakes themselves receive this pressure from the brake fluid. Drum brakes and disc brakes are the two basic categories of brakes. In both systems, the disc or drum is pushed against the wheel by the pressure from the braking lines, slowing the wheel down through friction. Drum brakes are less expensive but more intricate and have more parts.
Any step of such process can result in brake failure. The most frequent reason for failure is a brake line leak. Once there is not enough brake fluid remaining to transmit the pressure from the pedal to the tires, the brake fluid will gradually drain away. When the discs or drums become worn down and are no longer able to stop the wheels with enough friction, the brakes can also stop working. There may also be other, less frequent mechanical faults with the device.
Can worn brake pads turn on the brake light?
The brake warning light is most likely caused by a slight drop in brake fluid level. When it is safe to do so, you should stop, find the brake fluid reservoir using your owner’s manual, and fill it with the appropriate brake fluid. As a result, the brake warning light ought to turn off.
If the brake system warning light is still illuminated, a brake fluid leak can be the cause. Press down hard on the brake pedal when your car is parked in a secure location. The pedal may be leaking if you notice that it slowly descends to the floor. Search for any areas of yellowish liquid under your automobile. If you spot any, you probably have a leak.
Your brake pads may need to be replaced if the brake warning light is still on after you’ve checked for leakage. Your brake pads may have worn out severely if you have this light on. Some automobiles do have a distinct brake pad wear warning light that resembles this.
Can I simply top out my car with brake fluid?
You don’t need to add any brake fluid if it is at or above the “MIN line, indicating that the level is satisfactory. Add brake fluid until the level is just below the “MAX line if your fluid level is below the “MIN line. Then, carefully peel the reservoir top off. Avoid overfilling.
Can you add brake fluid on your own?
- Put your car in a level spot.
- If the brake fluid reservoir cap is dirty, clean it to prevent debris from getting into the reservoir.
- Take off the cap. You may need to have brake fluid changed at a shop if the fluid is particularly black or contains debris because it may be past its expiration date.
- Brake fluid should be cautiously and gradually poured into the reservoir until the maximum fill indication is reached.
- Screw the reservoir cap back on firmly.
- Once parked on a flat surface, drive your car for a short while, sometimes braking, and then check the fluid once again to make sure the fill was successful.
Avoid spilling brake fluid on your car or the engine bay since it might damage paint. If you do, thoroughly rinse it off with water. You can tell when the surface is completely clean because it is oily.
Can I still operate a vehicle with low brake fluid?
It is doable, but you must quickly refill the brake fluid. Since brakes utilize hydraulic fluid to operate, they are dependent on it for proper operation. Without brake fluid, your brakes will either fail completely or have an adverse impact.
