NO clue what is being said exactly, but I'll guess that your brakes feel soft ;).
IF I'm reading it right, you say that your brakes work ok then they go soft, which should indicate a leak in your brake lines. Check your fluid reservoir and see if it has lowered. If it has lowered at all, check all of your break lines for leaks, especially the one you just replaced. If the lines look good, also check the calipers and be sure those aren't leaking.
If you let the brake fluid run too low you could have sucked air into the lines, so even if you find a leak and fix it, you can still have issues. If you were unfortunate enough to catch an air bubble at the reservoir, you've got a LOT of line that the bubble has to travel through and be prepared to spend some time bleeding your lines to get the air bubbles out.
If you don't find any signs of leaks and bleeding your brakes doesn't help, let us know, then the fix gets a bit more complicated and we'll have to look at your master cylinder and possibly pumps. Good luck and let us know!

Hi @Samantha Watters,
Does this occur after driving the vehicle?
Do you regain normal brake pedal action if you "pump" the brake pedal 2-3 times?
If so and you have checked / replaced master cylinder and all slave cylinders, bled brakes and no leaks you may have a failing axle bearing.
A failing bearing allows the brake rotor to move and this creates air gaps. The pedal will go to the floor as the caliper fills with fluid to close the gap

There is no fluid leaks anywhere, I have changes the master cylinder twice, and have bleed the lines several times. The pedal works great after being bleed, but after driving it for a few minutes the pedal go back down to the floor.

Have you checked your brake booster for possible leaks? If somehow the booster develops a vacuum leak only after driving for a bit, that could be the source of pedal softness as well. The valve in the booster may also be damaged? See if you can detect leaks anywhere around that area.

jason, why did you replace the original brake hose?

My 2002 escape brakes are hard and no power to stop then it goes to normal. I checked fluid looks fine.
