My symptoms were:
Braking straight with light pressure. Pull to the left with medium brake pressure. And Instant Lane change during Massive Brake Stomp!!
My thoughts were, although I could use a complete brake system upgrade, I could get by with the band-aid fix. Cheap is good!

I installed stainless steel flex lines, on the front only so far, and Earl's Solo Bleeder's.

An easy install and instant gratification!

Sometimes 14 year old brake parts need attention too.
Big Red stops straight as an arrow. Still could use 1LE or better for the front.
