Just installed new front pads and springs. I cleaned the adjusters real good as they wer pretty rusty. Have not installed the drums yet because I squeezed brake handle to check cylinders and only one out of the four moves. Should they all move at same time? Brakes were working somewhat before I tore it all apart but not great. How do you test the wheel cylinders? Do I need to bleed lines first then check to see if they al move at same time?
