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.

Testimonial: "thanks for the info. very helpful. harry Newman"
Only 2 items can cause that. First one being air in the brake lines. If work has been done on the brake system then they weren't bleed properly. The other is a bad master cylinder.

SOURCE: brake pedal goes to floor
It sounds like you have quite a bit of air in your brake lines. You may need to have them bled out to relieve the spongeyness. If the brake fluid resivoir is staying full then this would be the most likely cause. Hope this helps.

You have Malfunction Indicator Lamp lite on your dash,
I assume for some time & ask if you have checked for the
ABS Braking System Codes,since the Stability Light is on
I will assume you have no owners manual & haven't given
much thought to going to a repair shop within a couple of days
of any vehicle issue
Need the codes,then have a shop diagnose that systems problems
Could be a Wheel Speed Sensor,or not

Tips for a great answer:
The speed of the vehicle
The lateral, or sideways acceleration of the vehicle
The difference between the desired yaw rate and the actual yaw rate is the yaw rate error, which is a measurement of oversteer or understeer. When a yaw rate error is detected, the EBCM attempts to correct the vehicle's yaw motion by applying brake pressure to one or more of the wheels. The amount of brake pressure which is applied varies, depending on the correction required. The engine torque may be reduced also, if it is necessary to slow the vehicle while maintaining stability.
VSES activations generally occur in turns during aggressive driving. When braking during VSES activation, the pedal may pulsate. The brake pedal pulsates at a higher frequency during VSES activation than during ABS activation.
