It is very possible you have a leak at the rear seal of the master cylinder, (pop the master cylinder cover and check the rear compartment for brake fluid loss), allowing its brake fluid to leak into the brake power assist booster and causing the interior vacuumn assist boosters diaphragm to crack and rupture from the brake fluids exposure to the diaphragm....the diaphragm is made of rubber and cant tolerate brake fluid attacking it...when this diaphragm leaks there is no more vacuumn power brake assist and the brake pedal becomes hard as a rock while attempting to stop.
Fix:
Replace leaking and defective master cylinder and replace defective vacuumn power assist brake booster, bleed and reibnspect all four brakes including brake lines and wheel cylinders for leaks and wear.
Consult a certified brake technician to work with you on this repair if you are not sure how to fix it, then watch listen and learn.
Happy Motoring.

Why is it hard to push down brake pedal?
A hard brake pedal can be caused by several different factors. It can be as simple as the brake pedal getting caught on something to the power brake booster being bad. You could also have a brake pad or shoe that is sticking, causing the brake fluid to boil. When brake fluid boils, it expands and can cause the hard brake pedal that you feel. A brake pedal that is hard to press can also be caused by a build-up of water in the brake line. The water in the brake line lowers the boiling point of the brake fluid. A hard brake pedal can also be the result of a restriction in the brake line, such as a bent brake line or foreign material in the brake fluid. The most common cause of a hard brake pedal is the sticking brake pad or shoe, causing the brake fluid to boil. Tracking down what is causing the hard brake pedal can be frustrating, to say the least. Take the vehicle for a drive and when you come back, feel your brake lines near the wheels. Caution: The line may be very hot! If one is extremely hot, you may have just found the culprit causing the hard brake pedal.

What happens when you run out of brake fluid?
The brake pedal will go to the floor but will have absolutely no effect on stopping the vehicle. When you push on the brake pedal it moves the fluid through metal tubes (called brake lines) to force the brake pads against the rotor which slows and stops the car. No fluid means nothing is in there to make the brake pads engage the rotors.

What is the problem when you can not steer nor brake the car 97 GMC astro its very hard t o steer the steering wheel and hard to brake its very hard when pressing the brake pedal?
For several years of the Chevy astro van had a power brake and power steering system that was linked together. Instead of a brake booster, the power steering pump provides power to the power brake system. Often, if the brake pedal would become hard to push, it is a power steering pump problem. Change the power steering pump and the power steering fluid and your problem may disappear.
