Which size drums on 69 Dart? And some other brake questions.

adjusters - no, but the springs have been under tension for 14 years and fatigue over time. I would particularly replace the front hoses, I presume that you are using old style brake fluid. Hoses can look fine and delaminate inside the hose and cause all sorts of grief. If you are going to replace the front wheel cylinders, you are going to have to take them loose anyway, so I'd replace them.
