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

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?
If you are losing fluid and the pedal is low, you have a brake fluid leak.
What would cause a hissing noise to come from the brake pedal on a 1990 ranger when it is pressed down to the floor and the brakes barely work?
Vacuum brake booster is defective or the hose going to the booster is leaking.
Why do the brakes go to the floor before beginning to respond?
you either need a new brake master cylinder or your brakes need to be bled
Why would a brake pedal held to the floor suddenly lose tightness and brakes not working?
Have your brake system checked immediately! (by a proffesional)
You replaced rear brake shoes and drums your brakes are now fading and have to be pumped to stop There are no leaks and the adjustment is up where it should be?
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.
The brake pedal slowly creeps to the floor when you hold the brakes on a 1994 Ford F-350 with a Diesel eng.?
Check your brake fluid. Next maybe your brake lines need to be bled. OR you just might need new brakes.
Having brake problems on a 95 ford ranger xlt 2.3l v6 you replaced master cylinder brake booster bled the brakes pedal still goes to the floor?
You need to bleed the brakes.
What is wrong with the brakes in 99 Renault Clio had to depress brake pedal to the floor in order to stop the car?
i do not no
What causes brake to go down to floor if brakes have been replaced?
Air in the brake system- Brake system needs to be bleed and fluid needs to be added while you are doing that.
Your truck makes a hissing sound when your brakes are engaged and your brake peddle travels all the way to the floor before stopping the truck also stalls when brakes are engages?
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.
