My jeep was fine until....

I have a 78 cj-5 that had a leak on the shaft coming out of the master cylinder.I replaced the master cylinder with a rebuilt one from NAPPA.Everything went on fine ,after I bled the brakes, I had no play in the pedal.Took it for a test ride and had alot of drag (the front brakes were smoking)I backed off on the rear brake line to releave the pressure,drove down the road and the pedal was still hard but my brakes did not stick or drag.What are some of the problems I may have, and solutions?This is my only source of going so I will be grateful for any input.

Is the rod from the pedal out of place ? did you loosen the m/cyl mounting bolts and check for that ?...I'd start there

If it comes with instructions, then it's not what the pros use.

Sometimes when you open the system(an old one), you can "upset" the proportioning valve.
Some time dirt can get to it or as simple as air or it just hasen't moved in along time.
My first step would be to tap on it lightly whit a small hammer. Try this with no brake pressure and then with some one on the brakes.
Check all possible venues before you replace this item (as it is $$ and not usually easy to find), but this is what it sounds like to me.
Good luck.

Dirtrod, when I got the new M/C,it didnt have the push rod with it. I had remove the old one and install it in the new one.The push rod had a washer attached to it and a snap ring on top of the washer.The snap ring did not completely cover the washer on the new M/C .Could the washer be putting the push rod in a bind?

Dirtdog, I am glad you brought the proportioning valve up,thanks for the tip but in the back of my mind I am praying that the valve is not the problem because they are rare and expensive.During a routine bleeding the valve does not need to be adjusted right?
