If the booster is out, it would be hard to push on the brakes. Maybe your new master cylinder is toast.

Lift that wobbly tire off the ground and give it a good shake to make sure the bearings and lugs are tight. Check the tread of the tire for distortion indicating a broken cord. Fix that shock. If the tire is out of ballance then a shock will damper the vibration.

check your alignment by using a tape measure and measure between in front of your tires and in back of your tires, side to side. I run with a little toe in, about 1/8 inch. Also use a plum-bob and see if your tires are straight up and down. You want the tread as squared to the pavement as adjustment will give you.
