Ford: abs brakes, abs brakes, ford escape

Question
We have a ford escape had the front brakes replace,we now have a pulsing on the brake peddle

Answer
The only thing this sounds like to me is you have a warped rotor somewhere.  You need to take the rotors off and have them checked out.  It sounds like they are warped.  A machine shop can do this for you.  You may can have them turned or you may very well have to replace the rotors if you wouldn't have enough material left on them after turning them.
