Check engine light, a discussion.
One of the most common things people bring their cars into shops for is to get their brakes checked. Just as common are those people who put off getting their brakes checked, presumably to save money, yet they quickly remember how expensive it is to put off getting brakes checked when other parts end up needing replacing as well. Since brake pads wear out as time passes, they need regular checking and replacements. How do you know when the pads have worn out? You will know that your brake pads need replacing because as they wear down, they will start squeaking when you go to brake. At that point, you will need to go to an auto repair shop and get your brakes checked.
