My husband accidentally used pwr steering fluid in brake resevoir. Brake pedal went to floor, one week later. Will drain and replace with proper fld. Could this have done any harm.

Yes, you will need to flush the entire brake system and change the master cylinder. The power steering fluid has eaten the seals inside of the master cylinder and if it is not removed from the system it will take out your wheel cylinders and caliper seals.

Late model cars use the brake m/cyl resevoir as asupply for the clutch system. Check for a line from theclutch m/cyl to a point in the brake m/cyl resevoir. If not follow the line back to the resevoir.

2004 f150 soft brakes

New to FixYa-not sure how this works.Soft brake are typically associated to a fluid/ master cylynder issue. Without viewing & knowing particulars via driving habits, mileage, etc, it is hard to duduce specific issues. Your front brakes have greater stopping pressures than the rear brakes which means they wear down quicker than the rear brakes. If you have a soft/mushy pedal, you may have worn brake pads which also leads to the brake fluid resevoir being low (shoe diminishment to increased fluid use-ratio)-you can fill the resevoir and pump up/ solidify the pedal but when you replace the pads, the fluid will overflow the resevoir.There are also indicators on brake pads that cause a high pitch squealing when the pads are low-again, without a visual or specific info like "do you hear any squealing while braking, how many miles on vehicle-the current set of brakes, do you tow anything, etc...", it is hard to diagnose; kind of like a doctor diagnosing a belly ache over the phone - there are so many factors/variables from the vagueness, it makes the situation a "guessing game"..If you can include more definitive info, it may narrow down the issue without a visual inspection. There are a lot of other components that could be the issues but the pads/low fluid will be the most common.Hope this does not cause more harm than good. G2

I should have said what kind of leak I have brake fluid leaking from the rear passinger tire

you mean from "near" your rear passenger tire. Tires don't have brake fluid in them...!
Take a look at the inner part where the wheel mounts to the axle. There is a brake line there, so look to see if it looks like the brake fluid is coming from it, (and that you verify the brake fluid resevoir under the hood is low) or that it might be from the brake drum area. If it's from the brake drum, you probably have a "wheel cylinder" leaking, and need to remove the wheel and drum to verify this.

1998 Lincoln Navigator, brake light on, filled fluid resevoir light went off, next day came back on. Brakes spongy. Replaced pads front and rear at 87,000 miles, currently at 111,000

Not completely sure here as i cannot see it but i would hazard a guess and say that the master cylinder needs changing ,but check the fluid level first and if low again then you have a fluid leak but where ?? could be a caliper seal or the master cylinder leaking out of the rear seal and its being sucked into the air intake via the servo vacumn pipe?? could even be a flexible pipe split or a damaged brake pipe ,Evan if pads on metal you should still have a hard pedal ,Have a good look around to see if its leaking first

Brake pedal goes to the floor? replaced all the brakes and bled them. worked for very short time and now the pedal goes to the floor.

If the fluid level is staying constant then it sounds like the brake master cylinder or the master cylinder booster. If the seals are bad on the master cylinder the piston just goes through the fluid. Many boosters use air pressure to assist in the braking proces and it could have a leak.
