What causes brakes to suddenly fail?
The most common cause of brake failure is loss of brake fluid. The fluid transfers the force you exert by pushing down on the brake pedal to the brake disks that slow and stop your car’s wheels. A bad brake cylinder can cause your braking system to lose power. A part called the brake booster can also go bad.
