281 is the brake switch circuit.
265 is a power issue to the ecbm
225 is a wheel speed sensor.

you need a scan tool for all these codes. a shop may be in order for you to have them check it for you.
as far as no brake pedal, you may be correct about the master. make sure your calipers and wheel cylinders are working as well.
