Your question: Why do car brakes suddenly fail?

The most common cause of failure is a leak in the brake lines. The brake fluid will slowly drain out, until there isn’t enough left to transmit the pressure from the pedal to the tires. The brakes can also fail when the discs or drums wear out, so they can no longer put enough friction on the wheels to stop them.
