Complete brake failure. Right front brake pad had over 1/3 pad material left. Pad material detached from the metal pad backing plate. Then the pad material got jammed in between the brake caliper bracket and the rotor. The lower caliper piston broke when I tried to stop after this happened. Then all of the brake fluid leaked about leading to total brake failure. I had brake failure a few seconds before the brake light came on. When this happened I could not stop and went into a ditch to avoid traffic. Brakes worked as normal before failure. Brake pad failure required replacement right front brake caliper, right front rotor, new pads, pad glides, new brake fluid and a complete bleeding of the braking system.
