Brake Master Cylinder problems of the 2008 Ford Focus

While driving vehicle will not stop. On highway and regular streets. Brake pedals applied but are pushed to the floor. To stop I pump brakes and eventually they come back. Reported problem to dealer but was told nothing was wrong. Have replaced master cylinder and brakes in the last year but problem still persists. Almost had accident yesterday and am terrified of driving car. Don't remember any recalls but have been reading other people's comments on this same problem. What is the fix for this!!! no one seems to know!!! this car still has low mileage I am the original owner of the vehicle but I had the same problems but didn't know what to do because I always took car to dealer for service and they kept saying nothing was wrong with the car. I have all of my service records and papers but sold the car to my daughter kelly wilmer last year and she keeps having same issues. I have told her to get rid of the car because it is not safe. I drove car for 10 years with this problem and was lucky not to have an accident but did have some close calls. At this point I want to know exactly what the problem is and how to fix it because she is a single mother with no money to be buying cars. I saw a complaint that it could be the abs pump but the 2008 was a one year design and can't be purchased anymore, if this is the case then we are screwed. Please advise what the correct fix is if you can.

Spongy braking issues, recently the brakes on my 2008 Ford Focus have become very spongy, I took it in to firestone and they could not find the problem. They said that my front and rear brakes were perfectly normal, but being that I drive my vehicle everyday I know that something is up. I am finding it hard to stop at red lights and on the highway. It's almost to the point where I have to press the brake peddle the floor to get the vehicle to stop. The mechanic said that it may be the master cylinder or a combination of other things, but one thing is true Ford needs to do a recall on this issue before someone dies or gets hurt. I pray this does not fall on deaf ears and action is taken!!.

The break master cylinder has been leaking since 70,000 miles. Since then, the break oil has been adding whenever a parking break light was turned on. I have driven more than 10 different used and new cars in domestic and import. This is first time to have the break master cylinder issue. It is now 156,000 miles. The leaking break oil seemed to be depend on the number of the break pushing. The oil doesn't seem to be leaking when the car is in parking. For example, I parked the car more than 3 weeks because I traveled. When I came back, I didn't notice the break oil level changed. The shortest refilling the break oil was within a week. One occasion, it lasted over 3 month. There was no car accident involved in this car. There was no mechanical modification done on any of the part. This was exactly the same car that came out from the factory. The driving condition was usually a city boundary with well paved road. The longest driving was 300 miles. The leaking oil usually went down clutch pedal that made the pedal slippery. If I had a hand towel to absorb the leaking oil, I had to change it once a month or two month. The break oil didn't seem to leak outside of the cabin. The engine compartment was clean and dry.
