Brake lights icons stay on mechanic at Toyota dealership state need new brak master cylinder and booster

My car experienced a failing brake actuator/accumulator. The first sign was the ABS and break lights accompanied by a whoosing sound. The issue causes intermittent system wide break failure and renders the car undriveable. Toyota had an extended warranty for this issue but that offer was closed by the time my car had the failure even though it was still under 150,000 miles.

Frequency when I start car makes a very loud , painful high pitch noise for anywhere from 5-15 seconds

My 2012 Toyota Prius is experiencing brake actuator pump failure, presenting diagnostic trouble codes C1253 (brake actuator pump motor stuck/locked) and C1256 (brake actuator pump motor overcurrent). These codes trigger ABS, brake, and VSC warning lights and disable ABS and stability control.
