What causes a soft pedal on a car?

If you’ve previously done some work like replaced brake pads or rotors, its common to lose confidence in the brakes. The pedal will feel soft and ineffective until the pads and rotors bed in (surfaces mate).
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.

What to do when your hard brake pedal is off?
Try pumping the pedal And bleed the master cylinder first by cracking the lines at the master cylinder while having a helper hold the pedal and do let the pedal up until the lines are closed. If you have a spongy pedal you still have air on the system so start at the master and then go to each wheel after that. Thanks for the idea.
What happens when the brake pedal goes to the floor?
Brake Lines, Brake Calipers Check: The first thought that comes to anyone’s mind when the brake pedal goes to the floor when engine running, is that there is a leakage in any of the brake lines outflows the pressure in the brake system. The first thing you require is to check the brake fluid level. If it is full capacity, then there is no leak.
Why is the soft brake pedal hard when the engine is off?
You need to take it somewhere and get it fixed. Of course the pedal is hard with the engine off, there is no power assist to help push the pedal down. Probably the seals on the calipers and/or master cylinder have been damaged by the contaminated fluid. I agree with Tardis. Trying to fix this yourself is way too dangerous.
What happens when a power assist pedal fails?
If it fails, the assist disappears but the brakes still work. A failed power assist manifests itself as a hard pedal, but does not affect the function of the brakes. But this repair will need to be diagnosed directly and done properly including flushing of the system. This is too important to be done by a novice. Take it to a trusted mechanic.
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.
Why does my brake pedal have holes in it?
This is the master cylinder that holds the brake fluid and produces the hydraulic pressure which actually makes the brake system perform its job. But unfortunately, it gets corroded from rust that makes it fragile and causes holes on its body through that brake fluid leaks out.

What causes a master cylinder to feel spongy?
Damage to the brake lines and rust can also make the pedal feel spongy when depressed. When you put your foot on the brake pedal, the pressure is transmitted to the master cylinder which in turn pushes the pistons present in the cylinder.
What to know about no brake pedal condition?
A good indication of this condition is lack of fluid flow from the brake bleeders. Ensure master cylinder is bench bled prior to installation. Follow the vehicle’s manufacturer-specified bleeding procedure.
