Check the ABS sensors, too -- if out of place, you could be having the ABS activate and that "pumps' the brake pedal.

Do both tie rods and the drag link, and buy a new steering damper too, you are due for all four. When the damper goes bad, the vibration batters the tie rod ends to death. Set new tie rods to the same overall length of the old ones and it will be close enough to drive to the alignment shop. Drag link isn't adjustable.

You will be stunned at the difference in handling when you replace this stuff, since you are currently darting all over the road.

When you get all that done, save your pennies for torque and thrust links in the back. Dollar to a donut, if you jack a rear wheel up off the ground and apply torque to a lug bolt, the wheel will move back and forth about an inch -- this means torque link (and probably camber and thrust link, too) are completely shot. Causes thumps under the rear seat on hard shifts, too.
