It’s essential to be proactive and address any issues promptly. The first step in troubleshooting is checking the trouble code. Your vehicle’s onboard computer generates this code and provides valuable information about the problem affecting your brake system. By accessing this code, you can gain insight into what may be causing the issue and take appropriate action.

You will need an OBD-II scanner or a similar diagnostic tool designed for reading codes from your vehicle’s computer to check the trouble code. Plug the scanner into the OBD-II port, typically located under the dashboard near your steering column, and follow the manufacturer’s instructions to retrieve the trouble code. Once you have this information, you can consult an online database or repair manual specific to your vehicle make and model to help decipher what that particular code means.

2-Replace the Faulty Brake Pressure Sensor

A culprit could be a faulty brake pressure sensor. This essential component helps to regulate the hydraulic pressure in your vehicle’s braking system, ensuring optimal performance and safety. Suppose you’re experiencing issues such as a spongy brake pedal, inconsistent braking power, or warning lights on your dashboard indicating problems with the service brake system. In that case, it may be time to replace the faulty brake pressure sensor.

Replacing the faulty brake pressure sensor is a simple task and can often be done by a knowledgeable car owner with basic mechanical skills. However, it’s important to note that working on your vehicle’s braking system requires caution and attention to detail. Start by locating the brake pressure sensor – typically found near the master cylinder or attached directly.

3-Fix the Faulty Brake Booster

One common issue that many drivers face is a faulty brake booster. If you notice reduced braking power or unusual noises coming from your brakes, it might be time to fix the faulty brake booster.

Start by inspecting the vacuum hose connected to the booster. Over time, this hose may become cracked or loose due to wear and tear. If you find any damage or improper connection, replace or reattach it accordingly. Check the check valve at the end of this vacuum hose for any blockage or debris that might hinder proper functioning.

4-Fill the Brake Fluid at the Appropriate Level

Maintaining the brake fluid ensures a safe and efficient service brake system. This simple task is necessary to avoid potential accidents or even costly repairs. To fix your service brake system, start by locating the brake fluid reservoir under your vehicle’s hood. It is usually found near the firewall on the driver’s side and has a small cap indicating brake fluid. 

Before opening the cap, remove any dirt or debris accumulated to prevent fluid contamination. Carefully remove the lid and inspect the current level of brake fluid. It should be between two markers labeled minimum and maximum. It’s time to add more liquid if it falls below the minimum. It can be done using a funnel to avoid spillage or accidental contact with painted surfaces, as brake fluids are known to damage the paint.

5-Reprogramme the Warning Light

Brakes are one of the most critical components of any vehicle, ensuring your safety on the road. When the warning light comes on, it could indicate several issues ranging from low brake fluid levels to worn-out brake pads. Sometimes, a glitch in the system may require reprogramming.

To begin with, start by checking if all connections related to the braking system are secure and free from corrosion. Loose or faulty connections can trigger false warnings. If everything seems fine externally, but the warning light persists, it’s time to delve deeper into reprogramming.

Open it up and check if the fluid level is below the minimum mark. If so, add more brake fluid until it reaches between the minimum and maximum marks.

Another reason the service brake system light illuminates could be worn-out brake pads or rotors. Over time, these components can wear down, causing decreased braking performance and triggering the warning light.
