No! When you press on the brake pedal, that forces fluid from the MC to the wheel cylinders. When you release the brake pedal, the brake shoe return spring forces fluid back to the MC and that's why you see fluid coming in the MC reservoir. If the piston cups in the MC are leaking, you'll see fluid dripping out the back of the MC. If you are not seeing dripping fluid, the MC is probably ok.
1. Fully depress the brake pedal, hold it, and start the engine. The pedal should move downward. This is a simple test to see if the booster is function under vacuum.
2. Jack up both rear wheels off the ground, at the same time, and place the TC in the neutral position using the right TC lever moving it in the half-way position. This is so you can rotate the wheels without fighting the drive-train. You can do the front wheels one at a time.
3. Turn the adjusting cam bolts at the top of the brake support plate - front bolt clockwise until against the drum and you can't turn the wheel and then back off until the wheel can be easily rotated 360 degrees. If you experience a slight drag in spots when rotating, that's ok. Turn the rear bolt counterclockwise to adjust.
4. After adjusting all the brakes, check the MC fluid level, it should be at the top, if not fill.
If brakes aren't much better, them you'll need to remove the wheel, the drum inspection cover and adjust toe/heel of the shoes.
Overtime the brake shoe springs work the cam bolts back and you gradually loose pedal, so periodical brake adjustment is required.
