Pulsing brake pedal

That is a very common problem with the Ranger/Explorer. I can tell you right now it is in all likelyhood in the ABS. I put 4 new rotors on my explorer and cleaned the sensors, No difference, It's just one of those things that I will have to dig into to find the real problem.

You are right that it is a very common problem on rangers/ explorers. The problem is usually a cracked tone ring inside the hub assembly and usually just replacing or cleaning the sensor itself will not solve anything. You need to have the entire hub assembly replaced. As far as I know Ford as updated the hub assembly and recommends that they be replaced in pairs. This is definitely not a warped rotor issue.
