Answer: Having proper working disc brakes is essential to operating a safe vehicle. If you have worn brake pads, operating your vehicle can be dangerous. Worn disc brakes can lead to braking failure and can cause accidents. Also, if you wait too long to get your brake pads changed, you can incur many additional costs. When the brake pads are completely worn, each time you step on your brake pedal, your vehicle’s calipers will be squeezing metal on metal. This can lead to further damage on your vehicle’s rotors, and you will then need to replace not only your brake pads but also your rotors as well.
