What happens if you pump brake pedal?
When you repeatedly pump the brakes you are pressurizing the system with hydraulic pressure, this is why the pedal feels harder and may get to the point where you can’t press it again. Btw, probably not a good idea to keep doing this — it may cause undue pressure on the brake lines and fittings.
What to do when your hard brake pedal is off?
Try pumping the pedal And bleed the master cylinder first by cracking the lines at the master cylinder while having a helper hold the pedal and do let the pedal up until the lines are closed.

How can you tell if your brake booster is bad?
There are many ways to identify a bad master cylinder or brake booster. You can feel brakes are so spongy or very soft under your leg, or there is a leakage in the master cylinder. You can also feel that the brake pedal is hard to press, or the engine is stalling and stop working while braking.
