How to know when to replace the brake pads in a Vauxhall Combo Life?

I have a Vauxhall Combo Life and I'm wondering how I can tell when I need to replace the brake pads. What are some signs to look out for and what is the recommended frequency for replacement?

When you start to hear squeaking or grinding noises when you apply the brakes, it's time to check your brake pads.

Another way to tell is by inspecting the thickness of the brake pads. If they are less than 3mm thick, it's time to replace them.

It's recommended to replace brake pads every 50,000 miles or every 2 years, whichever comes first.

Pay attention to how your car feels when braking. If it takes longer to come to a complete stop or if you feel vibrations, it could be a sign of worn out brakes.

To ensure the longevity of your brake pads, avoid heavy braking and try to anticipate stops in advance.
