Emergency stopping,brake pedal went almost to the floor,took long distance to stop,antilock pulsated just before stopping.Feels like uneven aplication of front and rear brakes. And what is the brake fluid level in the master cylinder? Should there be some air space under the cap?

Can you also you feel the pulsation in the steering wheel or the body of the car? If it is in the steering wheel then recheck the work that you did. Make sure that the hubs are clear of rust and torque the wheel nuts when putting the tires on.
To check if the rear are bad you can while driving down the road, lightly apply the emergency brake. If you feel the pulsation in the body then it is the rear brakes.
One last test that I have done is clamp off one brake caliper at a time using a clamp on the rubber line and seeing where the pulsation is coming from. Also if the antilock system is engauging there will be a pulsation in the pedal.
Yes a 1993 Chrysler / dodge / plymouth with Antilock brake system has lifetime warrenty on said system. It is a bad design and dangerous. Mine stopped working and it took extreme pressure on brake pedal plus emergency brakes to get it stopped.
check the rotors for scoring,worn rotors will "feel"like the abs is coming on due to the vibration caused.and will account for the extended stopping distance.
It went to the floor because you had to compressed the piston to get it over the new pads and rotors. The brakes need to be pumped up after you replace pads in order for the pistons to come back in contact with the new pads and take up the gap. Pushing the pedal to the floor is never a good idea and a good way to ruin a master cylinder in older vehicles.
As far as the pulsation, have the rotors turned. Make sure the wheels are torqued to the proper spec when you are done (140 lb/ft). Pump up the pedal when you are done and you should have smooth braking.
are all the tires same size. Inflated to the same PSI. How did you check the sensors, Did you ohm them. they should be the same. Still did you drive the car to make sure all the sensors still read the same as you speed up. You need a scanner for this. When you clear the light does it come on right away before you roll. If so you prabably need to get the control module rebuilt. If it comes on after you start rolling then its most likely a sensor.
The pulsating is the ABS system. It's actually pumping the brakes incredibly fast to even the braking to all wheels. There's sensors at each wheel and anytime it senses uneven braking, it's going to do this. You may want to pull the wheels and check the sensors and all of the connections and make sure there is no debris in any of the wheel sensor areas..
First, is the ABS light on? Does it come on when it's doing it? Make sure the brake fluid is full, and the brakes are still servicable, ie, pads still have meat on them. If so, the abs control module or a speed sensor might be on the way out. This is a safety issue, and I would recommend getting the truck to a good mechanic to have it checked out.
