The brakes on my Taurus have been acting up lately. I guess it would be called a "soft pedal" if I remember right. About a 1/3 of the time they brake normally, 1/3 of the time the pedal goes about half way to the floor and comes back if you pump it, and a 1/3 of the time they go almost to the floor before stopping. I checked the fluid in the master cylinder and it was a little low so I topped it off. It got a little better, but it still goes almost to the floor at times. Do I have air in my lines and need to bleed them, or could it be something else?  |

It ncould be the seals in the m/c. sometimes they invert and allow fluid to bypass.then they go back to normal.It would not hurt to have rear brakes ajusted to specs and entire system bleed.

Yes to both your questions.
Before I start if you don’t feel confident working on brakes then don’t; take it in and have them inspected and repaired.
The first thing to do is get all the wheels and rear drums off so you can make sure everything at the wheels and lines look normal.
If not repair or replace as required.
If so adjust the rears and bleed the complete system.
If the pedal is still playing games change the master and rebleed the system.
Dan.

Also look at the rubber hoses for any bulging when brakes are applied.

Update. I've now replaced the power booster AND the master cylinder and bleed the lines and still have a soft pedal. I have not seen any rubber hoses bulging. What's next?

Did you inspect the rear brakes as retired suggested? If the rear brakes are worn down it can cause the symptom you are describing. Look closely at the rear wheel cylinders for seepage too. You may need to pull the rubber boot back and look inside to see if there is any fluid coming around the pistons of the wheel cylinders.
