How to troubleshoot a faulty brake pedal in a Vauxhall Easytronic?

My Vauxhall Combo Life's brake pedal has become increasingly harder to press. What could be causing this issue and what steps can I take to address it?

It is possible that your brake pedal is becoming stiff due to a leak in the brake fluid. This could be caused by worn brake pads or a damaged brake line. It is important to have your brakes inspected and serviced by a qualified mechanic as soon as possible.

Another possible reason for a stiff brake pedal is a malfunctioning brake booster. This device helps amplify the force applied to the brake pedal, so when it is faulty, the pedal can become harder to depress. It is recommended to have a professional mechanic diagnose and replace the brake booster.

Sometimes, the issue can be as simple as air in the brake system. This can happen when there is a leak or when the brake fluid has not been changed for an extended period of time. A mechanic can easily bleed the brakes to remove any air and restore proper functionality.
