How do I troubleshoot a malfunctioning brake system in my Vauxhall Movano?

I recently noticed that my brake pedal feels spongy and the brakes are not as responsive as before. What could be the possible causes and how can I fix it?

John, it is likely that there is air in your brake lines causing the spongy feeling. Start by bleeding your brake system to remove any air bubbles. If that doesn't improve the responsiveness, there may be an issue with the brake fluid or components that require further inspection or replacement. It's also important to check for any leaks in the brake lines or cylinders.

Hey John, make sure to also check your brake pads and rotors for wear and tear. If they are worn out, they can affect the brake system's overall performance. It's recommended to replace them every 50,000km or as needed. Don't forget to also check the brake master cylinder for any leaks or failures.

John, another possible cause could be a faulty brake booster. This component assists in applying pressure to the brakes when you press the pedal. If it is malfunctioning, it can lead to a decrease in brake system performance. Consider having it checked and replaced if needed.
