89 Ranger losing power and breaks after hard breaking

After a hard breaking to avoid a road hazard my 89 Ranger 4cyl began losing power. Engine continued to run fine but the truck began to lose ability to maintain speed. As though there were no power to the transmission. Also noticed the breaks seem to be gone, pressing the break pedal goes alway to floor. Checked break fluid and transmission fluid both were full, no leaks. Had no problems before having to hit breaks hard (did not lock breaks or skid) to avoid an obstacle in the road. Both problems seem to be related but can't figure out how.
Anyone have any suggestions as to what may have happened?

Thanks for any thoughts or suggestions.
