1- check for vacuum leak

2- check the vacuum hose going to booster , do you have any ?

3- if you do have a good vacuum and still service booster , then the brake booster needs replacement , as long as the brake master cylinder is not leaking, you can tell if there is evidence of brake fluid .

Please let me know if you need anything else on it

Hope I was helpful to you

A Positive Rating is Much Appreciated
