Vehicle has approximately 38,000 miles, 2007 Toyota Tacoma. I was traveling approximately 3 mph when four indicator lights illuminated and a warning alarm constant tone. At that point I lost all power to the braking system. I did not experience any issues leading up to this incident and the dealership has been unable to diagnose the cause of the complete loss of power to the brakes. The dealership stated I would need to replace the entire abs actuator assembly (master cylinder assembly, with engine control module, with booster pump). Toyota currently experiences a national back order on the required parts to repair the vehicle (part numbers 47050-04041 and 47070-04020). I am concerned that there is a larger problem with the braking system that has not been addressed by Toyota. I was further told that this issue is extremely rare but with a back order on the parts and no anticipated delivery date, I am very skeptical. It seems there have been some braking issues with other Toyota models around the same time frame.
