Modern vehicles have many advanced features to help you understand your braking system and give you a smooth braking experience.
The service brake system is one of these advanced features, which indicates a problem with the braking system.
It is possible for the service brake system warning light to illuminate for many different reasons.
The first step is diagnosing the vehicle to determine which part is faulty.
The faulty part must be repaired or replaced once it has been found.
In this article, I have discussed the possible causes and solutions to fix the service brake system.
What Does It Mean When It Says Service Brake System?
The dashboard will illuminate the service brake system light whenever there is a problem with the braking system or brake sensor.
With these features, the driver will be able to understand that the braking system is malfunctioning.
As a result, the driver can avoid accidents by stopping the vehicle.
If you see a red or orange service brake light on your dashboard, inspect, diagnose and solve the problem.
You should only drive the vehicle for a short time before fixing the problem.
How to Fix Service Brake System [05 Methods]
You can fix the warning light by replacing the brake pressure sensor, troubleshooting the error code, replacing the brake booster, filling the low brake fluid, and reprogramming the warning light.
You can easily fix the service brake system warning light once you identify which of these issues is causing it.
01. Check the Trouble Code and Solve the Problem
Check the trouble code when the dashboard flashes the service brake system light.
Identify the code and problem with an OBD-ll scanner.
Resolving the problem will eliminate the service brake warning light.
Alternatively, you can take the vehicle to a mechanic, who uses an advanced scanner to diagnose and troubleshoot the problem.
02. Replace the Faulty Brake Pressure Sensor
If the brake pressure sensor is faulty, it causes the service brake system light to illuminate.
You need to replace the faulty brake pressure sensor to fix the service brake system.
The brake pressure sensor is usually located at the side of the master cylinder, but in some vehicles, the sensor is located at the ABS unit.
You can easily replace it if you have a little experience with braking system parts.
Otherwise, you can hire a mechanic to do the job for you.
Replacing a faulty brake pressure sensor will cost you around $220.
03. Fix the Faulty Brake Booster
The brake booster is a vehicle component that multiplies the force applied by the driver to the brake pedal.
A faulty brake booster can also cause the service brake system warning light to illuminate.
Replacing the faulty brake booster will remove the brake system warning light from your dashboard.
The cost of replacing the brake booster is approximately $100 to $450; if you hire a mechanic, the cost may increase to approximately $250 to $850.
04. Fill the Brake Fluid at the Appropriate Level
Insufficient brake fluid level is a common cause of the service brake system warning light on your vehicle.
The ECU triggers the service brake system light when the brake fluid level is low or dirty and causes the service brake system warning light.
In one to two minutes, you can check the brake fluid level.
Replace dirty brake fluid or fill the cylinder with premium brake fluid if the level is low.
Changing the brake fluid every 30,000 miles or after 02 years is recommended.
Follow the recommendations to avoid unexpected problems.
05. Reprogramme the Warning Light
There are times when programming malfunctions cause the service brake system warning light to come on.
In this case, there are no problems with the brake system, but your vehicle’s dashboard illuminates the service brake system warning light.
Reprogramming or resetting the warning light will solve the issue.
