    also try to adjust the rear brakes up they are needing adjusted out some I bet..

    If it has a brake booster, that could be leaking -- do you hear air hissing/escaping when you operate the brakes?



    Could also be the master cylinder leaking by an o-ring internally.

Check your ABS Wheel speed sensors. If 1 or them is not working properly the whole system doesn't work properly. Also remove the tire and try to wiggle or move the hub assembly, if it moves it needs replaced. I had this problem with my 96 Cavalier and it took me forever to finally figure it out. New brake pads and 2 master cylinders later along with countless times of bleeding I share this with you. I hope it helps.

Are there vacuum hose on the brakes hydraulic system?


NO. the vacuum is used to make the brake pedal easy to push, power brakes. the pedal would be hard without vacuum, that is why the pedal gets hard with the key off and engine not running. the problem you are having is more of a hydraulic problem.
Have the brakes checked asap. the brake system may have a leak causing the pedal to go low. check the fluid level and if it is low or empty then there is a problem, could be a rotted brake line leaking or a wheel cylinder leaking.

Brake pedal goes to floor


You either have a huge leak in the brake system or you have a defective brake master cylinder. Always have an expert check this before replacing parts.

Sounds like you may have a hydraulic leak somewhere. Check the rear wheel cylinders and front brake hoses going to the calipers.

My 1997 chevy 1500 z71 brakes suddenly going all the way to the floor. Checked brake fluid and it was low. Could be wheel cylinder? Master cylinder? or ?


well, check the brake lines for leakage after adding brake fluid to the full mark. If the brake pedal goes all the way to the floor, it's likely there is a leak somewhere after the master cylinder. If the pedal gets hard after adding fluid, and pumping it several times with the car off, then the master cylinder is still ok.

If air has gotten into the master cylinder, it may have to be bled out on a bench, or using a scanner if that's the way your vehicle is.

Bleeding the Brake System (ABS) Auto Bleed Procedure NOTE: Perform a manual bleeding procedure. If the brake pedal height and firmness results are not achieved, perform the auto bleed procedure below.
NOTE: Perform this procedure when replacing the brake pressure modulator valve or electro-hydraulic control unit.
  1. Perform the manual brake bleeding procedure. Refer to Bleeding the Brake System (non-ABS).
  2. Check the master cylinder fluid level often to prevent running the system dry.
  3. Press the brake pedal firmly and run the Scan Tool Automated Bleed Procedure (for Gas engines) once, or the Function Test (for Diesel engines) four times. Make sure to release the brake pedal between each test.
  4. Perform the manual bleed procedure again. This should remove the remaining air from the brake system.
  5. Bleed the system as many times as needed to obtain the appropriate feel of the brake pedal.

You changed the master cylinder and vacuum booster and have no leaks anywhere, but did you bleed the entire brake system after you did this work? A little bit of air in any of the lines will make the brakes ineffective.

Brake peddle goes to floor when you feather the brakes


the pedal will go to the floor when there is a leak in the brake system or air is in the system due to lack of proper bleeding, when a major component is replaced; caliper, master cylinder etc. if the reservoir is low you have a leak. if no apparent fluid is visible, it may leaking into the master cylinder.

Brake pedal goes to floor when engine is running


You need to see if you have fluid in the master cylinder's resivoir.. low fluid or no fluid could be a low break pads or out of adjustment problem ....if fluid is low add dot3 break fluid..and step on the pedal a few times...if the level seems to hold it could be out of adjustment or low pads . If the fluid leaks out then you have a leak and must attempt to find it yourself or with a mechanic. It is possible you may have air traped in the system and it may need to be bled out by a mechanic. I say a mechanic because this is a crittical safety system needed to stop the car !! If you are not sure of how to repair a leaking brake line or caliper or master cylinder leave it to a pro . At least you may be able to find out what is leaking with this help .

96 Taurus brakes


Presuming you have NO leaks in the hydraulic system,it would be a bad brake master cylinder.What's happening is,the piston inside the master cylinder has rubber seals,and when the pedal goes to the floor,the master cylinder is leaking internally,past the rubber seals.If the brake booster was bad,the symptom would be an extrememly HARD,unresponsive,brake pedal,and the engine would idle terrible (vacuum leak).Good luck.
