abs light/brakes

My 96 acura's abs light is on and there is a noise from the front right corner where i believe the brake pump is.

My brakes go down ok, but if i slightly relase them a little and then press then them again they go down lower and eventually to the floor where they even dont work. i basically have to release the brake pad so that it goes all the way back up so that i can start over.

I was told it is the abs module, but im not sure if it is that or the abs brake pump.

Anybody have any ideas?

Thanks

Mo
