Brake petals go all the way to the floor

I have a 1996 Chevy Tahoe.... At first the brake petal was very hard to push down which made me think it was the Power Brake Boost. After awhile I started to hear "grinding" noises which made me think I needed brake pads. The other day while driving I could bearly stop my truck, like the brakes went out. I had to go through two stop signs without being able to stop. The petal went down to the floor. I just had the power brake boost replaced but the brakes wont do anything. They go straight down and feel very loose. I was told the piston was sticking out "to far" and I may need rotors and pads. I feel like screaming, what could be wrong?

    Thanks for your reply! I won't be able to replace the master cylinder right now due to the expense of my 'Power Brake Booster'. I just discovered that my Brake light is on. What could this mean? The ABS light would come on from time to time but now it the red (! brake) light.

    Probaly one of the sensors on the brake system is defective, Or the plug on them could have corrrosion on the terminals , Allso one way you can tell if the master clyinder is at fault is ,Start it up end if the brake pedal go to the floor press on it , End if it builds the (Pressure) Back up on the pedle , Then hits the floor when you try end move the vehicle, Then you no the master cylinder is shot,

    Sorry there i ment to press the pedle a couple of times up & Down.

    Thank you! I will try that and see. I had someone look at my truck Friday and I was told that I need a Caliper, Rotor and Brake Pads. But I will do what you said above to see if my Master Cylinder is shot.

    I found out that the Emergancy Brake was on and that eliminated the Light issue. Now I have a new problem. I had the extra work done I needed for my truck (caliper, rotor and brake pads). Soon as I tried to shift into drive to see how the brakes work and wouldnt do anything. What could this be a cause of?

SOURCE: front brakes feel mushy after being replaced

You have air in your break lines. The two ways you can solve this problem is have the breaks blead to get the air out of the lines, or you can take the top of the break reservoir and pump your breaks to the floor. DONOT DO THIS With the car moving. What this will do is force the air to the reservoir.

SOURCE: 1991 honda civic brake light stays on need to push brake pedal to

Sounds like you might have a caliper that is stuck and is not fully disengaging. If it is in the rear then you may have a bad rear caliper. Twoo things you can try. One is to crawl under the ca and adjust the tension two nuts on the emergency brake line. If that does not resolve the problem then remove the back tire and try to spin the drum or rotor whichever you may have. If it does not spin then try adjusting the e brake cable more if it still does not respond then you need to do a brake rebuild. Also does it pull while it is dragging? If it is then you will need to rebuild the brakes no matter what.

SOURCE: 2001 sonoma parking brake petal wont lock into place

There's a ratchet in the top of the pedal which holds the pedal down when depressed. This ratchet is worn, broken, loose, or it just needs lubricating. I would first try WD-40 on the top of the pedal where it attaches to the frame/chassis.

SOURCE: Power brakes not working

No such thing as vacuum lines to the master cylinder. You do have a vacuum line on the brake booster (power assist). When you step on the pedal do you hear a whoosing sound down by your pedal. This is a leaking Booster. Needs replacement.

When you step on the brake does the engine rpm change. This is a leaking check valve (one way air valve).

2005 jeep liberty brake lights don't work, none of them but fuses and brake light switch are good.

maybe brake light switch located near your brake petal needs adjusting...its simply a push button that the brake petal hits as the brake petal is depressed usually u can just pull on them toward you and they'll "self-adjust" after pressing on brake petal...push on brake petal with ur hand and make sure this button is depressed while the pedal is down...

My brake light won't turn off even if my foot

Your brake switch is just hung up. it is located directly above the brake petal and is attached to the petal bracket-use a flashlight and get down low enough to see up under the dash where your brake petal is, it will be hooked onto the petal bracket-just move it, it is probably just mis-aligned.

I have a 1998 chevy s10 it has a good brake pedal with the engine off but with it running the pedal go'es to the floor and you can hear air at brake booster

Check for fluid leaks and your brakes. If you see no leaks and your brakes are in good shape replace the brake master cylinder and bleed the system. The air you hear is because the pedal went to the floor. If the booster goes bad the pedal will get so hard you can hardly push it at all. I think you will find if this happened suddenly either you have a major leak or the master cylinder went bad.
