CHECK BRAKE ACTUATOR WITH TOYOTA HAND-HELD TESTER
Are you sure it is bad?? very expensive guess.
first of all, forget this idea of the pump.
you need a shop to check this as a wheel speed sensor is the most common failure and is much cheaper than what you asked. the trac system is offline till the abs system is back up and repaired.
the shifter may be a bad fuse for the brake lights. have that checked as well.
