Should I be able to push the brake pedal to the floor?

How much force does it take to push a brake pedal?
The average person can press on the brake pedal with about 70 lbs. of force. However, to stop a moving vehicle, disc brakes require 800-1,200 psi at the calipers. The force you put on the pedal is amplified by all the parts of the system.
Why is there no pressure in my brake pedal?

How do you fix a excessive brake pedal?
Bleeding your brakes is an important step in brake pedal travel repair and other brake issues. Use a jelly jar half full of brake fluid and a short hose to depress your brake pedal. While depressing the pedal, rotate the star wheel to lose up the clearance. Then, go back one click when the wheel scrapes.
What happens when you press brake pedal?
When you push on the brake pedal, brake fluid travels through the brake hoses and converts your “push” into energy that brings the car to a stop. The heat and pressure generated when slamming on the brakes can cause tears and cracks in the hoses. Such damage can result in fluid leaks that eat away at your brake pads.
What do you do if your brake pedal sinks to the floor?
If your brake pedal suddenly sinks, it could indicate problems with your brakes caused by the master cylinder, a brake fluid leak, or ABS unit leak.
