Question about Cars & Trucks
If you break fluid level is correct and your break pedal goes down to the floor means that your master cylinder is going bad and you might loose your breaks completely if not checked or replaced. Your breaking system is down to the last O ring inside the master cylinder, once that rubber O rings goes you will not have any breaks at all. Master cylinders have a number of rubber O rings that work like a plunger or piston that produce pressure within the breaking system. When the first one wears down due to age, your pedal begins to loose break pressure and you have to pump your breaks several times to gain breaking. You are now down to the last rubber O ring and a warning that your master cylinder needs to be checked. You can still use your breaks but only for a few days before the other rubber O ring gives out too. Once both O rings give out you completely loose your breaks.

Since there is no loss of fluid we can rule out any leaks. A poor booster would make you apply the brake much harder to stop. So somehow you are not developing the necessary pressure for the brakes to function. The pressure is developed by the master cylinder seals. You can get a rebuild kit or a rebuilt master cylinder but the real pain is bench bleeding the new one. Luck to you.

There is either air in the system or a leak in the clutch slave cylinder. Check your fluid make sure it is full and the cap is tight.

Check the reservoir to be sure the fluid is full. If not, top it off and try it again. If there's still trouble building pressure, pump the brakes a bunch of times, and then check around each wheel for fluid on the ground. If you see none, it's possible that you have a break in the line somewhere through the chassis and that the fluid is leaking out inside. If you see no evidence of leakage, and the reservoir is still full, you need a new brake master cylinder - what will have happened is that the diaphragm around the plunger inside the master cylinder (which moves through the cylinder when you push the pedal, and forces fluid out to the wheels) has a hole or tear in it, so instead of pushing the fluid out to the brakes, the plunger simply moves through the fluid. It never builds pressure, and your brakes don't work.
