Was the brake pedal sinking before the parts were replaced? If it was not, a good suspect is the master cylinder was damaged from improper bleeding procedures.
For the ABS system, most likely a scanner is needed to open some of the valves in the ABS hydraulic controller so trapped air can be bled out. The diagnostic fault codes need to be read and recorded too to see if the problem is related.
