Sounds like a bad brake booster. If you are getting an extended braking distance, you may also want to check for a rear wheel cylinder leak.AnswerYou also might want to check to see if the engine vacuum is low. If the vehicle is newer than '90 or so, it probably has a sensor that determines if the rear wheels are braking. If hydraulic pressure is uneven between front and rear you will usually see a brake indicator light come on. I agree that the vacuum assist may be the culprit, but also make certain that you are getting enough vacuum to the brakes. Low vacuum can be caused by a number of problems, so it may take a little checking. I would recommend a vacuum gauge. They are quite inexpensive and can be picked up at most auto parts stores.
Also check to see if you have a vac. leak at the booster canister where the vac. line plugs into it, if the master cylinder is leaking brake fluid through the rear seal of the spool valve it can enter the power brake booster and destroy the diaphragm seal causing the power brake booster to fail....thus hard as heck brake pedal(meaning you have no vacuumn assist) it's easy to check for a brake fluid leak....just pull the master cylinder mounting bolts off the power brake booster(either 2 or 4 bolts or nuts) and look at the rear side of the master cylinder seal to see if brake fluid is prevalent, also with a light look inside the power brake booster for tell tale signs of brake fluid leakage.
Press brakes with firm, hard pressure.
No, you just hit the brakes HARD.
They need to be loosend up a liddle bit.
Depends on how hard you press the brakes

if it is hard to press on the brakes it usually indicates that you have a malfunctioning brake booster. Since brake boosters are vacuum assisted, it could also be that you have a disconnected vacuum hose or a leaking hose.
yes it might if u press hard enough if they do go out u will no
You probably need new brake pads very soon.
you change the brakes,check brakes fluid,bleed the brakes why is hard to stop in a 1988 sliverado?
hard breaking or no back brakes. also, back brakes adjusted wrong.
more than likely you have air in brake line and need to bleed brakes
Low oil level? Oil may "slosh" forward on hard stop causing a temporary drop in oil pressure
Perhaps a vacuum leak, Check all hoses
press the brakes and then press the start/stop button
It would be hard on the brakes and fuel mileage.
you should gently press the brake pedal and gently press the gas pedal, the increase friction will dry the brakes.....
press down hard on the brake pedal, and continue to steer the vehicle.
The power brake booster is leaking vacuum and that makes the engine die when the brakes are applied. Replace brake booster.
i ment that if the sensor in the dash stays on after i press the brakes and dosent go off till i turn the car back on and dont press the brakes?
Repairing disc brakes is not particularly difficult, but since this is your first time, I believe it would be smarter to have it done by a professional.
You have a warped rotor.
Compared to todays modern brake systems they will feel hard. Also depends on if they are power brakes or not. Some cars of that era did not have power brakes and they were very hard to push.
The right side brake caliper may be frozen.
Power booster failure or vacuum supply to booster failure.
Because something is wrong, take to a brake rather than risk your ( and OUR ) life.
