Brake system lights require full attention when they come on the dashboard. It's not only a reminder for vehicle maintenance, it's also a sign that something is wrong. With RoadPro Assistance you can request a detailed diagnosis and mobile assistance if the problem worsens.
Avoid ignoring the vehicle warning signals and follow our recommendations for turning off the brake system light.
What Is Service Brake System?
Service brake system is essential to maintain complete safety on the road, as it helps prevent accidents. In addition, its correct use is mandatory according to driving regulations. The service brake system communicates to drivers behind when there is a slowdown.
The main functions of the brake system lights are:
- Determine the braking intensity: lights vary according to the braking force. They look dim and low contrast when there is a stop, but if the braking is abrupt, they are activated very noticeably.
- Alerts pedestrians: brake system lights are necessary to warn cyclists or pedestrians of the presence and speed of the vehicle. So if visibility is poor due to rain or darkness, alert lights announce your passing.
Both of these features help avoiding disturbances that include damage to third parties while driving.
What Are Service Brake System Lights?
Each icon on the dashboard corresponds to a different signaling that varies according to the model and make of the vehicle. The most common ones in the service brake system are the parking brake, brake and ABS. Discover how each one works:
Parking Brake Light
This is a red warning light with an icon of the letter "P" in a circle with parentheses, or the word "BRAKE" on the dashboard. It comes on when the parking brake is engaged and goes off when the parking brake is released.
If this brake system light appears without setting the parking brake, it is necessary to have it checked. On the other hand, it may only come on when you try to move the car without removing the parking brake.
Brake Light
Brake lights react independently of the vehicle's headlights. When the brake pedal is pressed, the "BRAKE" signal is activated both externally and on the vehicle's dashboard. This is because there is a reduction in speed and, when illuminated, allows other drivers to be forewarned.
Now, if the "BRAKE" light appears before you start the unit, it is important that you call an expert. This is a clear warning that something is going on in the hydraulic system.
ABS Light
ABS ensures that the wheels do not lock up when the brakes are applied. If it does not work properly, traction stops, which can lead to accidents on the road because control of the entire unit is lost.
ABS light is located on the dashboard as follows: "(ABS)". This icon illuminates in short intervals when the anti-lock mechanism is activated.
Why Does The Brake System Light Come On And How To Turn It Off?
When the service brake system lights are activated, the indicator on the dashboard illuminates. There are vehicle models that include an icon for each light. These include:
- The one that indicates that the ABS is activated.
- That of the parking brake.
- The one that warns that something is wrong with the service brake system in general.
But what if the brake system lights are on without being activated? One reason could be that the parking brake is on, but there are many other possibilities.
Read on to find out what can be the causes and how to solve them.
Disable Hand Brake
It is very common to forget to disengage the parking brake after parking. Although driving with this brake on does not cause serious breakdowns, it does wear out the brakes faster than normal.
Check that the parking brake is not engaged before moving the vehicle, this will turn off the indicator. If the indicator light is still on, there are other problems, for example, brake malfunction.
Check the Hand Brake Switch
There are two types of brake system light switches:
- Mechanical: released by means of a lever or pedals on the center console.
- Electronic: activated by the power switch.
The dash icon light comes on for either of these two switches. If the alert is still on even when the parking brake is disengaged, there may be problems with the switch. In this case it is recommended that you call a travel mechanic for roadside service.
Change or Replenish Brake Fluid
The fluid in the hydraulic system is critical to proper brake function. When the proper fluid needs to be changed or replenished, the emergency brake light activates. What factors cause brake fluid instability? These are the causes:
- Humidity generated by the air.
- Brake fluid aging.
- The brake fluid has changed from a liquid to a vapor state.
The frequency brake fluid should be changed is 1 to 2 years. However, it will depend on each vehicle and the manufacturer's recommendations.
RoadPro Assistance has the technicians trained to perform this roadside work in the shortest possible time. After obtaining the recommended maintenance, the brake system light may turn off.
Replaces Brake Pads
As in the case of the brake fluid change, the brake pads must also be replaced. Otherwise, the brake system light will remain on. On the other hand, there are vehicle models that do not indicate this type of failure. To identify brake pad wear, pay attention to these signs:
- Grinding noises when braking.
- Abnormal vibration in the steering wheel or brake pedal.
- Use more force than usual to press the pedal.
If you observe these characteristics, do not hesitate to diagnose the condition of the brake pads.
Restart The Light
Reset the dashboard light if the parking brake is already released or if you have already performed the relevant checks of the hydraulic system and it is still on. This is because sometimes the brake system light does not work efficiently.
When this happens, the brake system lights tend to flicker for no apparent reason or come on arbitrarily. It is recommended that you seek help from professionals in the area to solve this problem.

ABS Maintenance
ABS activates the service brake system signal. It is a safety mechanism that helps you drive on slippery surfaces. Now, if the ABS light comes on and flashes from the dashboard, it means that there is some deficiency. These are the faults that cause this alert:
- Blown fuses.
- Damaged or fused sensors.
- Wiring in bad condition: burned, broken or worn out.
- Faulty controllers.
When ABS performance is not optimal, driving complications arise such as:
- Wheel locking.
- Inability to control tire direction.
- Loss of traction.
