Is it necessary to change the brake pads on the Audi A6 regularly?

I've heard that changing the brake pads on my Audi A6 can be costly. How often should I change them and what are the signs that they need to be replaced?

Brake pads should be replaced every 50,000-70,000 miles, but can vary depending on your driving habits. It's important to check them regularly and replace them when they start to wear down.

Signs that your brake pads need to be replaced include a squealing or grinding noise when braking, longer stopping distances, or a vibrating brake pedal. Don't delay in getting them replaced, as it can greatly affect your car's braking performance.
