like the other guys said......clean the booster before installing a new one.
second.....don't buy the cheapest product....they are boomerangs. Defective master cylinders happen alot these days.....be ready. (uneducated rebuilders who may be illiterate, for example)

try: Engine off, automobile in Park, push not ordinary on the brake pedal. IF the pedal is going slowly all a thank you to the floor, the grasp cylinder is shot. IF the pedal is going down yet to not the floor then stops, air interior the lines someplace. you need to not be waiting to purpose the brakes till the grasp cylinder is working properly.

New or Rebuilt master cyl....and did you clean out the booster.
if the new unit leaks then it must be defective...

It may just be residual brake fluid in the booster still seeping out.
