Not holding pressure

Well we have tried everything you and a few other people have said and still nothing. infact when we do bleed the brakes when i push the pedal down and then hold when my husband is releasing the pressure and fluid my pedal is already all the way to them ground. we are beyond confused with this situation. is it possible that the booster isn't working? how would i tell is the booster is bad?

You need a new master cylinder- If the booster was bad the BRAKE pedal will feel the total opposite, it will be VERY hard to press down. THAT MASTER CYLINDER IS DEFECTIVE GET ANOTHER ONE. Good luck and contact if you need more help.

I replaced both front calipers and rotors on my 08 Escape. I then bled the brakes, but the pedal goes to the floor. What is going on ?

It has ABS so you have to bleed the brakes from the brake caliper up to the reservoir using a positive pressure brake bleeder. The unit holds the fluid and pushes clean fluid and the air up to the reservoir under pressure.

Manually bleeding brakes

You don't have to, but if they have never been bleed before and you have over 90k miles on it, it wouldn't hurt! Look at its condition, if it's Clear and nothing is floating in the fluid and the brake is high and firm when depressed, it would be best to leave it alone.

But, if the brake pedal is spongy and pumps up after depressing it a few times, then bleeding the system will remove any trapped air bubbles and it will also remove any contaminants or moisture that may have collected over time.

If you have access to a Pressure Bleeder, you would have less problems as long as you don't over pressurize the system.

Also, make sure you use Dot 3 Brake Fluid if you do bleed them.
And if you have never bleed the system and don't have a pressure bleeder, do your best not to don't push the brake pedal to the floor during the bleed process. If you do, it could cause damage the Master Cylinder's internal seals causing them to leak which will cause your brake pedal to sink while holding pressure like at a stop light, causing brake presure failure and the need to either rebuild the Master Cylinder or replace it with a new or rebuilt one!
Don't rush through the prosses and doing this on a less humid day is always best as Brake fluid tends to draw moisture from the air, causing your new brake fluid to become contaminated prematurely.

One other thing, soak the Bleeder Valves on the Calipers and or Wheel Cylinders with "PB Blaster", its a rust busting penetrant, much Better and Faster then WD40 and will aid in loosening rusted bleeder valves without breaking them.
Hope this helps.
Happy Saturn Motoring!

Replaced some brake line, rear pads and one rear wheel cylinder. Now no pressure and nothing happening when trying to bleed.

Does the car have ABS ? And does it have an equalizer block for the 4 wheels ?
It sounds like the ABS has been affected, or there is an equalizer block that is stuck on the front wheels only.
Can you open the bleeder or the rear line on the master cyl and get fluid to come out by depressing the pedal ?

You didn't bleed 4 times, as you have no pedal pressure.

Front brakes are dragging on the 97 oldsmobile pedal has endplay before the rod engages with the master cyclinder. I replaced the master cylcinder adn flushed the front brake lines.

Try bleeding the front brakes a little and see if they are holding pressure. If they are, it could be an adjuster problem, or fault with the master cylinder.
If there is no real pressure when bleeding - It's most likely a siezed piston or siezed caliper.
I presume the Brake pads and Discs are the correct type - as there are often many different models fitted, so identification is imperitive. Some are a few MM above others. Worth a double check.

04 Focus SVT- All brakes will bleed out except the right rear..??

Have somone help you as you bleed the brakes. Have them pump the pedal 3 times and hold the pedal down with constant pressure while you crack the bleed valve open to the problem caliper. Don't let them release the pedal until you have closed the bleeder valve. Continue this process until you have fluid coming out without air. Periodacillay check the master cylinder to be sure it remains full enough so as not to allow more air in because the resivouir ran to low during the bleeding process. If when you are done and the brake light continues to be on then you will need to bleed the proportioning valve until the system balances out on line pressure.
If this works can you please give me a rating??? Thank you.

Please help!!!

You should have a crush washer on each side of the banjo bolt. You may be loosing your pressure to everything else by all the brake fluid leaking. You may have to go through the motions a few times before you see the fluid come out of the rear.
