You could have a clogged brake line, most likely one of the front rubber ones.

The Brake booster might not be working correctly. Run the engine for a few moments, then turn the key off. Once the engine dies, press the brake pedal a few times. You should hear a hissing noise each time you press the pedal. Then hold the pedal down and start the engine. The pedal should move and get softer. If none of this occurs, verify that the booster has a vacuum source. If the booster has a vacuum source, and still does not boost the pedal effort, the booster is more than likely bad. One other alternative would be a bad check valve. Simply remove the valve and blow into it. It should blow easily in one direction, and not at all in the other.

What would cause the brake pedal to be hard and not go to the floor and doesnt engage brakes?

Your power brake booster may be defective. You may have a vacuum leak or the booster itself could need replacing.

Can the brake booster cause your brake pedal to go to the floor?

No, a busted brake booster will not cause the brake pedal to go to the floor. It will however cause the brake pedal to be extremely hard to push. A defective master cylinder will cause what you describe. Replace the master cylinder and bleed the brakes. It can because it happened to me. The booster lost vaccum and the pedal went to the floor. Sorry, you are wrong. The only reason the pedal went to the floor was because the master cylinder failed. The brake booster only boosts the pressure on the master cylinder and allows you to not have to push so hard on the brake pedal. Cars of yesteryear did not even have a brake booster and they stopped just fine albeit you had to push the pedal allot harder than with power brakes. A failing brake booster will not cause your pedal to go to the floor although it might cause it to go lower than normal before the brakes apply. As long as the master cylinder is good you will still have brakes, but you will have to really push hard and might even have to pump them up in order for them to stop the car.

Just changed your front and rear brakes and shoes. The brake light turns on until you put in more brake fluid. The brakes feel if they were almost touching the floor at times. What could cause this?

Try bleeding your brakes. If there is air in the system it can give a spongy feeling to your brake pedal and require you to pump your brakes and/or put your brake pedal to the floor.

Why do the brakes go to the floor before beginning to respond?

Have your brake system checked immediately! (by a proffesional)

This one is easy. Brake booster diaphragm is ruptured, causing a massive vacuum leak, which will cause the engine to run poorly when the brakes are applied. A loss vacuum assist will make it difficult to stop the vehicle.

Check your brake fluid. Next maybe your brake lines need to be bled. OR you just might need new brakes.

Air in the brake system- Brake system needs to be bleed and fluid needs to be added while you are doing that.

How to tell if you need your brakes replaced?

The best way to tell when you need brakes is by squeaking, when the brakes are rubbing against the metal, when your brake pedal goes all the way to the floor and when you are running out of break fluid.

Why on a 1985 jeep the brake peddled goes to the floor?

More than likely, there is air in the brake line or a leak in the line. Go to a mechanic and have the brakes "bled". He'll know what you are talking about. It's fairly inexpensive to do. Bad brakes, bad master cylinder, broken brake line, low brake fluid.

Brake Pedal Goes to the Floor After BleedingAlthough there could be more than one reason, I suspect that even though you may have bled the brake system, AND the brake fluid reservoir is full, your brake bleeding was not successful, and you STILL HAVE AIR IN THE BRAKE LINES, or in the wheel brake slave cylinders.

Brake Pedal goes to floor after changing brakes on 2003 Saturn L200 and bleeding brakes throughly What could be problem Car is mint too new to be master cylinder 30K miles?

After changing the brakes the first few times you press on the brake pedal it will go to the floor; that's because the calipers haven't been pushed back to position. Remember that you had to retract the calipers completely before you could put in the new brake pads. Sometimes it takes a few pumps before the calipers are back in position. Make certain that the brake fluid is all the way up, then bleed the brakes again, and watch that fluid level. If it goes low for just one pedal push then you'll suck air again and you'll have to start over. Just one bubble of air in the brakes will cause trouble.

How do you adjust the rear brakes on a 1990 Nissan pick up with new brakes and they have been bled and pedal goes down almost to the floor?

If your brakes are new and the system has been bled, your next step is to see if you have a leak in any of your brake lines and also check your brake master cylinder to see if it's working or not.

Why does the brake peddle goes to floor?

Low brake fluid, drums/rotors in need of replacement, pads in need of replacement, air in the brake lines, worn master cylinder, brakes out of adjustment... all possible reasons.
