Brakes were working fine, coming off freeway, was coasting thru light, traffic stopped, brakes no longer worked, brake pedal was suddenly flush with floor. Rearended a car, car started jumping forward. Had to use the emergency brake to stop the car. Car was towed after accident, not because it was not driveable, it was not driveable due to brake problem. Repair shop said brakes failed to vacuum hose breaking, no warning prior to losing brakes.
Brakes failed while going downhill on a wet but clean road. 58 degrees outside. Pedal felt firm and normal but brakes didn't slow car. 2 seconds of direct pressure yielded nothing. I then lifted my foot and repplied the brake with incredible force. 1 second passed with no response and suddenly the brakes grabbed and stopped the car. Scary.
While traveling at approxmimately 20 mph attempted to stop vehicle and brakes failed to slow vehicle down. Consumer's vehicle struck another vehicle, causing no injuries. Dealership has not examined vehicle.
