Why is my brake pedal so soft and squishy?
Having the air into the brake line is the most common cause of spongy brake. The air restricts the fluid from flowing properly that further affects the evenly distributed hydraulic pressure which makes the brake squishy.
What causes the brake pedal to go to the floor?
There are two types of master cylinder leaks: an external brake fluid leak and an internal leak from a damaged piston seal. Both failures will cause a loss in hydraulic pressure to the brakes which results in the brake pedal failing and going to the floor.

When the brake pedal is pressed, the master cylinder sends hydraulic fluid with the help of a brake booster through the brake lines to the caliper. The hydraulic pressure created is what pushes the caliper to the rotor. When you release the pedal, the calipers retracts, letting the rotors spin freely.

How to diagnose soft brake pedal master power brakes?
The easiest way to diagnose this problem is to pump the brake pedal gently a few times. In doing so, the pedal should become firmer with each gentle press of the pedal. If it does, then the obvious approach of bleeding the brakes must commence.
What causes a soft and spongy brake pedal?
Corrosion inside that wheel cylinder can cause brake fluid to leak resulting in a loss of hydraulic pressure. This leads to a low or soft/spongy brake pedal. If the vehicle has a rear brake drum/shoe and pumping the brake pedal improves the brake pedal, the rear shoes may be out of adjustment.
