how can i tell that my abs module/ pump is gone? on 2005 Toyota Avalon

just replaced pads and calipers in front.....caliper was frozen on passenger's side for some time....wore down my pad....also had passenger rotor when i apply brake it goes to floor but does stop car, yet when i pump the brake it comes up to where it was before the replacing of pads and calipers
