Has anyone had the bar linkage to front brake system bind up?I disconnected the linkage near the brake to isolate to see if the trouble was in the front section or rear.It is in the rear.I oiled it a lot.It did break loose but not loose enough.Guess I have to keep working it.

It is a common problem. The bushings expand to hinder the rotation of the shafts. The best fix is to replace the bushings with bronze or other similar material. If you have the time and patience you can remove all lubricant and then wear in the shaft by rotating until loose enough to move easily. Then when lubricated they will not bind.
