Did you bleed the brake lines? That may be the problem why the pedal goes all the way to the floor and only works when pumping it. It's the master cylinder. I don't care if you DID change it, it's bad. If it has the rear caliper with the emergency brake built in, the piston works on a ratching system. If you recently changed the pads, try setting the parking brake a few times and see if that improves the stopping. You no wat my anser is the that bad your's is so leave me aalone...
I need a daigram of the rear brakes being changed
You have a hole in your brake line.
did the parking brake get set, or the shoes adjusted too tight?
Be pointless. The point of anti-lock brakes it to effectively "pump" the brakes for you.
Stop the car in a pulsating manner.
Gently pumping your brakes.

Depend on what year cadillac you are talking about, and what model.
i have a 93 nissan and the front brakes are getting hot when driving
No
Test brakes lightly after driving through deep water.Brakes may pull to one side or may not hold at all.Dry brakes by driving slowly in low gear and applying brakes.
The pumping and releasing of brakes by the unit is brake pressure modulation
