I remember reading something about this kinda problem years ago.

In a nutshell... lf a front line is swelling internally, the effect of the resulting restriction seems to have been like a time delay in the application of pressure at the brake (similar to a vacuum signal delay device in some emmisions control plumbing). Just a fraction of a second difference in application time, side to side goes a long way. Seems to me, the restricted line was on the front brake OPPOSITE the direction of the pull. I also seem to recall that the line itself showed no sign at all of bulging from the outside. The mechanic finally changed out the line and sectioned it in one inch sections and found only a very short distance (like an inch) that was restricted.

Sorry I am so sketchy, but I thought it might be worth contributing to the discussion.

I can sure tell ya that mis-adjusted drums in the front will make it pull... WOW!!! Me peepers bugged out and bounced offthe windshield.
