Why are my brakes so soft?
The most common reason for a soft brake pedal is simply air still in the system. 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 necessary answer is bleeding the brakes.
What is a spongy brake pedal?

How long can you drive without brake fluid?
You can't drive a car without brake fluid because the fluid is what powers your brake system. The function of the brake fluid is to transfer hydraulic pressure from the pedal to the brake pad through the fluid line. So the absence of the brake fluid means the brake pad won't respond when you move your pedal.
Why did my brakes stop working all of a sudden?
The most common cause of failure is a leak in the brake lines. The brake fluid will slowly drain out, until there isn't enough left to transmit the pressure from the pedal to the tires. The brakes can also fail when the discs or drums wear out, so they can no longer put enough friction on the wheels to stop them.
Why do brakes have a soft pedal?
Over time and after prolonged use, the brake fluid absorbs the moisture and pushes out the air. Flushing the brake fluid prevents the old fluid from boiling, which can cause the soft brake pedal. If you keep the integrity and the health of the oil, then make sure you keep clean and fresh fluid. This can protect and preserve the other brake components and prevents further and more expensive replacements.
How to diagnose a soft brake pedal?
Component failure is another way to diagnose a soft brake pedal, like problems with the wheel cylinders or calipers. The master cylinder usually dictates that the internal seals have failed, and can be dangerous when a sot pedal gets worse. Pump the pedal gently and then hold the brake pedal, and if you see it creep downward, you are more than likely having a master cylinder that is leaking internally and not able to keep the right amount of pressure, causing a soft brake pedal.
Why do brake calipers rust?
Similar to brake lines in your car, the disc brake calipers can also become corroded with rust due to the buildup of damage over time. The brake disc calipers are the component that clamps the brake pad down against the brake rotors in order to slow down the vehicle by pressing on the wheels. If the brake disc calipers become corroded, this can cause the internal piston seal to leak the brake fluid from the fuel system.

Either of these leaks can cause a soft brake pedal, since both failures can cause a loss in hydraulic pressure on the brakes, causing the brake pedal to fail and go to the floor.
How does a drum brake work?
Drum brake systems feature a drum that rotates along the wheel, while inside of the drum is a set of brakes that are forced against the drum by the pistons in the wheel cylinder. Three wheel cylinder piston moves against the brakes due to the hydraulic pressure generated from the brake pedal being depressed. If there is a soft brake pedal, this will not happen.
