Brake Drum Wheel Cylinder Problems of Chevrolet Suburban

While driving the vehicle at highway speeds northbound on the FL turnpike, the brake pedal became very rigid and would not allow me to press the brake pedal down as usual. Furthermore, I had to apply a tremendous amount of pressure on the brake pedal to engage any sort of braking whatsoever. In a split second, I had to pull to the shoulder of the highway and continue applying very hard pressure on the brake pedal until the vehicle finally came to a full stop. I turned the vehicle off, started it again, tried coasting and stopping the vehicle and the brake pedal continued to be very difficult to press and would not engage and provide normal braking pressure. I then had the vehicle towed to the nearest Chevrolet dealership and they diagnosed the issue as being a bad pump impacting the master brake cylinder. Parts are supposedly on back order with no timeframe given as to the repair.
